The implementations of the methods addAll, removeAll, retainAll are omitted in the MyList interface. Implement these methods.

/** Adds the elements in otherList to this list.
* Returns true if this list changed as a result of the call */
public default boolean addAll(Collection<? extends E> c)

/** Removes all the elements in otherList from this list
* Returns true if this list changed as a result of the call */
public default boolean removeAll(Collection<?> c)

/** Retains the elements in this list that are also in otherList
* Returns true if this list changed as a result of the call */
public default boolean retainAll(Collection<?> c)

Write a test program that creates two MyArrayLists, list1 and list2, with the initial values {"Tom", "George", "Peter", "Jean", "Jane"} and {"Tom", "George", "Michael", "Michelle", "Daniel"}, then perform the following operations:
■ Invokes list1.addAll(list2), and displays list1 and list2.
■ Recreates list1 and list2 with the same initial values, invokes list1.removeAll(list2), and displays list1 and list2.
■ Recreates list1 and list2 with the same initial values, invokes list1.retainAll(list2), and displays list1 and list2.

Java Programming :

Email username generator Write an application that asks the user to enter first name and last name. Generate the username from the first five letters of the last name, followed by the first two letters of the first name. Use the .toLowerCase() method to insure all strings are lower case. String aString = “Abcd” aString.toLowerCase(); aString = abcd Use aString.substring(start position, end position + 1) aString.substring(0, 3) yields the first 3 letters of a string If the last name is no more than five letters, use the entire name. If it is more than five letters, use the first 5 letters Print the email username you generated with @myCollege.edu appended

Create a simple Java class for a Month object with the following requirements:

 This program will have a header block comment with your name, the course and section, as well as a brief description of what the class does.
 All methods will have comments concerning their purpose, their inputs, and their outputs
 One integer property: monthNumber (protected to only allow values 1-12). This is a numeric representation of the month (e.g. 1 represents January, 2 represents February, etc.)
 A constructor that takes no arguments, and sets the monthNumber to 1.
 Add a second constructor that takes in an integer argument to set the initial monthNumber for the new Month object. Use data protection to prevent the user from entering a number less than 1 or greater than 12. When a non-valid input is entered, throw a new IllegalArgumentException.
 A setMonth() method that takes an integer and uses data protection to prevent the user from entering a number less than 1 or greater than 12. Also throw an IllegalArgumentException if an illegal value is entered.
 A getMonth() method that returns the monthNumber as an integer.
 Add a String array property that holds the values of the month names (e.g. monthNames[3] would hold the value “March”). Remember, you can leave the 0th index blank/null
 Add a toString() method to use the monthNumber property to return the name of the month as a String. Use the private global String array with the names of the months in it to return the proper String based on the monthNumber.
 Add an equals() method that takes in a month object and returns a boolean based on the values of each object’s monthNumber
 Add a compareTo() method that takes in a month object and returns a negative number if the called object is smaller than the passed in object, a positive number if the called object is bigger than the passed in object, and zero (0) if the two objects are equivalent.

Create a simple program using Java that demonstrates the month object with the following requirements:

 That creates a month object using the no argument constructor.
 A second month object is created using the constructor that takes in an integer argument.
 Additionally, use either a do or while loop to get the user to enter a number between 1 and 12 using the setMonth() method on the 1st month object. The loop will continue until they enter a valid number.
 The program will display the month number for both of the objects using the getMonth() method.
 Display the month names using toString() for the months created, and see whether they are the same or not.
 Additionally, use the equals() method created above to show whether the two months are equivalent to each other or not.
 Use the compareTo() method created above to show which object is the biggest.
 Use appropriate try and catch statements to properly handle erroneous input by the user.

I have no idea on coding this. The files I need for this exercise are main.cpp, makefile, Executive.cpp, and Executive.h. So, will someone help me on this exercise? If so, then that will be great.

1)  Write a python program that opens a file, reads all of the lines into a list of strings, and closes the file. Use the Readlines() method. Test your programing using the names.txt file provided.
2) Convert the program into a function called loadFile, that receives the file name as a parameter and returns a list of strings.
3) Write a main routine that calls loadFIle three times to load the three data files given into three lists. Then choose a random element from the title list, two from the name list, and one from the descriptor list to generate a name. Print the name be in the form shown (you have to add the "the"):
title name name the descriptor
For example:
King Ludovicus Botolf the Bowman
Print the name to the screen.   
Submit your python file (.py) to Sakai

Part 2: Writing Files (Optional Extra Credit 20 pts)
Modify the program to generate 10 names and store them in a list.
Write a function, dumpFile that writes the list to a file called "CharacterNames.txt" There should be one Character Name on each line in the file.
Test the program to be sure it works

Im stumped at number 2

here is what i have for number 1

f = open('names.txt', 'r')
lines = f.readlines()
for line in range(len(lines)):
lines[line] = lines[line].rstrip()
print(lines)
f.close()

JAVA 1 PROGRAMMING QUESTION

In this program you will be writing a class that will contain some methods. These will be regular methods (not static methods), so the class will have to be instantiated in order to use them.
The class containing the main method will be provided and you will write the required methods and run the supplied class in order to test those methods.

? Specifications

• There are two separate files in this program. The class containing the main method is supplied, and you will write a new class containing the methods you will write.

? The code for the testing class is given below. In order to test the code you write, you will need to rename this file as you have all of your program files, as outlined above. You will need to change the calls to the methods to reflect the class where your methods are located. Do not modify the logic in this file to make it fit your methods. Part of this problem is to meet the specifications of the test program.

• Name the file (and class) you will create to hold the methods, MethodPractice (with the addition of your name data as above). This is the file that will have all of the methods other than the main method.

The Methods to Write

• In the file called MethodPractice you will write the following methods:

  • displayLine()

    • This method will not accept arguments nor will it return any values.
    • You may use the illustrated “Basic void Method” up above.
    • This method simply displays a line by using: System.out.println("--------------------");
    • Make sure your method displays 20 dashes.

  • displayMessage()

    • This method will accept a String as an argument, but will not return a value.
    • This method will accept a String message and simply display that exact message on the screen.

  • sumNumbers()

    • This method will accept two integers as arguments.
    • This method will add those two integers together and return the sum.

  • isGreater()

    • This method will accept two integers as arguments.
    • This method will use if and else to test the two numbers to see if the first one is greater than or equal to the second.
    • If the first number is greater than or equal to the second, the method will return a boolean true. If the first number is not greater than or equal to the second number, then the method will return a boolean false.
    • This method could use two return statements. However, use only one return statement at the end of the method. You can accomplish this by setting a variable to one boolean state of true or false, and then returning that variable.

  • setBulb()

    • This method will accept a boolean argument, but will not return a value.
    • Based on a received boolean value, this method will use if and else to display a message of either “The bulb is now on.,” or “The bulb is now off.”

The Instance Variables

? Make all instance variables in the MethodPractice class private.

• There are instance variables at the beginning of the MethodsPractice class. You may change those, but you will need to be consistent with the method calling from the main method in the MethodTest class.

The MethodTest.java Class

? Be sure to rename this file as you do all of your files, as outlined above, and upload this file along with the MethodPractice file. You will also need to modify the method calls to match your class name for the MethodPractice class.

• Below is the class by which your methods will be tested. It contains the main method with calls to each of the methods you are will write in the MethodPractice class. Use this class to test your methods.
• Remember to make the necessary modifications mentioned above.

Write the following classes: Class Entry: 1. Implement the class Entry that has a name (String), phoneNumber (String), and address (String). 2. Implement the initialization constructor . 3. Implement the setters and getters for all attributes. 4. Implement the toString() method to display all attributes. 5. Implement the equals (Entry other) to determine if two entries are equal to each other. Two entries are considered equal if they have the same name, phoneNumber, and address. 6. Implement the compareTo (Entry other) method that returns 0 if the two entries have the same number, -1 if this.number is smaller than other.number, and + 1 if this.number is > other.number Class PhoneBook 1. Implement the class PhoneBook that has a city (String), type (String), entryList (an Array of Entry). Assume the array size = 10 2. Implement the constructors to initialize the city and type. 3. Implement the method addEntryToPhoneBook(Entry e) that adds an entry to the phone book. 4. Implement the method toString() that displays all attributes and all enties information of the phone book. 5. Implement the method displayAll() that displays all entries in the phone book. 6. Implement the method checkEntryByNumber(String number) that takes a number and returns the entry with that number if it exists. 7. Implement the method checkEntrisByName(String name) that takes a name, and returns an array of the entries that start with this name or letters. 8. Implement the method removeEntryFromPhoneBook (String number) that removes an entry from the array of entires in the phone book. Class TestPhoneBook 1. Create a phone book and initialize its attributes. 2. Add 5 entries to the phone book list using the method addEntryToPhoneBook() 3. Display all entries in the phone book. 4. Display the entry information for a given phone number if it exists. Give the appropriate message if it does not exist. 5. Display all entries starting with the letters "Abd" 6. Remove a specific entry from the phone book. Display the proper message if it was removed , or if it did not exist. 7. Sort and display the entries of the phone book (Bonus). Java NetBeans.

In Java

We define BigNumber a number consisting of 0<N<21 elements.It can be negative in which case it will have a minus sign in front. Without modifying main method complete the methods add, subtract and reverse. Hints: class java.math.BigInteger would be very useful. For reverse method number== new StringBuffer(number).reverse().toString(); can be used however when you reverse a negative number the negative sign should stay in front. Thanks.

public class MD3 {

public static void main(String[] args)

BigNumber BigNumber1 = new BigNumber(args[0]);
BigNumber BigNumber2 = new BigNumber(args[1]);

BigNumber1.add(BigNumber2);
BigNumber1.display();
BigNumber1.reverse();
BigNumber1.display();

BigNumber2.subtract(BigNumber1);
BigNumber2.display();
BigNumber2.reverse();
BigNumber2.display();
}
