Write a Java program (single file/class) whose filename must be Numbers.java. The program reads a list of integers from use input and has the following methods: 1. min - Finds the smallest integer in the list. 2. max- Finds the largest integer in the list. 3. average - Computes the average of all the numbers. 4. main - method prompts the user for the inputs and ends when the user enter Q or q and then neatly outputs the entire list of entries on one line and then the minimum, maximum, and average. values on separate lines with nice readable labels. 5. Make sure your code runs without error and handles bad inputs and 0 and negative numbers are valid. 6. Followed instructions and include to get full credit file must include your name, date, class and Javadoc code comments for each and every method as well as logic comments.m

Java program

Create class DateClass with the following capabilities:

Output the date in multiple formats, such as

MM/DD/YYYY
June 14, 1992
DDD YYYY

Use overloaded constructors to create DateClass objects initialized with dates of the formats in part (a). In the first case the constructor should receive three integer values. In the second case it should receive a String and two integer values. In the third case it should receive two integer values, the first of which represents the day number in the year.

If someone enters the day as the 14 and the month is june, the program should be able to convert that to the day out of 365 for the third format. No null values. The program should convert whatever the user enters and print out all three date formats correctly.

Task #3 Experimenting with an array of random integers (Week 2)
Make sure that the following 3 experiments are done repeatedly by generating a new set of integers to fill the array. For this iterate 10 times and observe results for consistency.
• Make the array size reasonably large (say a thousand) and an even number.
• Choose the version of nextInt() that allows you to set a cap on the random integers generated (set it to a few thousands, but way less than the maximum integer).
• Do the following experiments:
o Count how many integers in the array are odd and even. Are the odd and even counts almost equal?
o Find the minimum, maximum, and average of the integers in the array. Keep track of the minimum and maximum of the three quantities across runs.
o Sort the array by writing an inner and an outer loop. Count the number of times you needed to swap integers.

Using Java

Write only “stubs” for methods in the Figure, Rectangle, and Triangle classes:

Consider a graphics system that has classes for various figures — say, rectangles, boxes, triangles, circles, and so on. For example, a rectangle might have data members’ height, width, and either a center point or upper-left corner point, while a box and circle might have only a center point (or upper-right corner point) and an edge length or radius, respectively. In a well-designed system, these would be derived from a common class, Figure. In this homework assignment, you will implement such a system.

The class Figure is an abstract base class. In this class, create abstract methods for draw, erase, center, equals, and toString.

Add Rectangle and Triangle classes derived from Figure. Each class has stubs for methods erase, draw, and center. In these "stubs", the method simply prints a message telling the name of the class and which method has been called in that class. Because these are just stubs, they do nothing more than output this message. The method center calls the erase and draw methods to erase the object at its current location and redraw the figure at the center of the picture being displayed. Because you have only stubs for erase and draw, center will not do any real “centering” but simply will call the methods erase and draw, which will allow you to see which versions of draw and center it calls. Add an output message in the method center that announces that center is being called. The methods should take no arguments.

Define a demonstration program for your classes which contains main. Test your programs:

• creating at least two Rectangle objects and two Triangle objects.
  • All instantiated classes have an equals and toString methods because these are abstract in the Figure class.
  • In this part of the homework, equals can simply return true, and toString can returns a String announcing that toString has been invoked.
• "draw" all of the objects you just created
• "center" at least one Rectangle and one Triangle object

In main, make sure that you tell the user what's going on at each step.

Your output should consist primarily of messages from your stub methods. An example of the output from your program might be the following (note: output from main method is shown below in italics):

  ** Create 2 triangles **
  Entering Figure Constructor for triangle 0
  Running Triangle constructor for triangle 0
  Entering Figure Constructor for triangle 1
  Running Triangle constructor for triangle 1

  ** Create 2 rectangles **
  Entering Figure Constructor for rectangle 0
  Running Rectangle constructor for rectangle 0
  Entering Figure Constructor for rectangle 1
  Running Rectangle constructor for rectangle 1

  ** Draw both triangles **
  Entering draw() method for Triangle 0
  Entering draw() method for Triangle 1

  ** Draw both rectangles **
  Entering draw() method for Rectangle 0
  Entering draw() method for Rectangle 1

  ** Center one triangle **
  Entering center() method for Triangle 0
  center() calling erase()
  Entering erase() method for Triangle 0>
  center() calling setCenter() to reset center.  
  Entering Figure's setCenter() for figure 0
  center() calling draw()
  Entering draw() method for Triangle 0

  ** Center one rectangle **
  Entering center() method for Rectangle 1
  center() calling erase()
  Entering erase() method for Rectangle 1
  center() calling setCenter()
  Entering Figure's setCenter() for figure 1
  center() calling draw()
  Entering draw() method for Rectangle 1

you are required to use only the functional features of Scheme; functions with an exclamation point in their names (e.g., set!) and input/output mechanisms other than load and the regular read-eval-print loop are not allowed. (You may find imperative features useful for debugging. That’s ok, but get them out of your code before you hand anything in.)

Write a function minMax that, given a list of integers, returns a tuple containing the smallest and largest element in the list. Just return (0 0) for the empty list. > (minMax (5 4 3 2 1)) (1 5)

var x;
function  sub1() {
  document.write("x = " + x + "");
}
function  sub2() {
   var x;
   x = 10;
   sub1();
}
x = 5;

Problem: Implement a class named StringParser, along with specified methods, that can read words from a text file, parse those words (such as finding palindromes), and write those words to a new file More specifically: 1. Write the StringParser class so that it has the following methods: a) public static void main(String[] args) -- The main driver of the program. Prompts the user for an input file, an output file, and a choice for what kinds of words to output. b) public static void rawOutput(File in, File out)-- Parses an input file, writing each word from the input on a separate line in the output file. c) public static void palindromeOutput(File in,File out) -- Parses an input file, writing only the palindromes to the output file, in alphabetical order, one line at a time, without repetition. Palindromes are words that read the same forward and backward, ignoring digits and punctuation. d) public static void hundredDollarWordOutput(File in, File out) -- Parses an input file, writing only the $100 words to the output file, in alphabetical order, one line at a time, in uppercase, without repetition. $100 words are found by assigning $1 to A, $2 to B, and so on. For example ELEPHANTS is a $100 word because: E + L + E + P + H + A + N + T + S is 5 + 12 + 5 + 16 + 8 + 1 + 14 + 20 + 19 = 100 e) public static boolean isPalindrome(String word) -- Determines if a word is a palindrome (reads the same forward and backward). The method is case-sensitive, so it will say that dad and DAD and d-a-d are palindromes, but Dad and d-ad are not palindromes. f) public static String cleanup(String word)-- Takes a string and removes all non-letters, returning an all uppercase version. For example, this input: "A man, a plan, a canal. Panama." will produce this output: "AMANAPLANACANALPANAMA" g) public static int wordValue(String word)-- Returns the monetary value of a word, found by assigning the value $1 to A, $2 B, and so on, up to $26 for Z. The method will ignore differences in case, so both A and a are each worth $1. It will also ignore any non-letters in the input. 2. Create your own input test file, and use it with your code to generate three output files. 3. Upload all five files (Java source code, input file, three output files).

Describe the characteristics of situations when generators are a good solution? python
