First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "PasswordChecker" (without the quotation marks) that gets a String of a single word from the user at the command line and checks whether the String, called inputPassword, conforms to the following password policy. The password must: Be exactly three characters in length Include at least one uppercase character Include at least one digit If the password conforms to the policy, output "The provided password is valid." Otherwise, output "The provided password is invalid because it must be three characters in length and include at least one digit and at least one uppercase character. Please try again." Some other points to remember... Do not use a loop in this program.

The Character class offers various methods to assist us in finding a digit or cased letter. Remember to press "." to locate these methods and to leverage the online resources shown in our course thus far." For this PA, do not use pattern matching (aka "regular expressions").

Inheritance – Address, PersonAddress, BusinessAddress Classes

Assignment

Download the Lab6.zip starter file. Use 7zip to unzip the file using ‘Extract Here’. Open the project folder in IntelliJ.

Examine the Main and Address classes. You are going to add two classes derived from Address: BusinessAddress and PersonAddress.

Create BusinessAddress class

1. Select package edu.cscc and create a new Java class called BusinessAddress  
2. Make the class extend the Address class
3. Add two private String fields businessName and address2
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println()) // Here is the 1st place I'm getting stuck ?? All I did was create the BusinessAddress class. I appreciate your assistance

First line – the businessName field

Second line – the address2 field if it is not null or empty

Third line – the StreetAddress field if it is not null or empty

Fourth line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Create PersonAddress class

1. Select package edu.cscc and create a new Java class called PersonAddress
2. Make the class extend the Address class
3. Add a private String field personName
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println())

First line – the personName field

Second line – the StreetAddress field

Third line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Modify Main class

Add the following three BusinessAddress objects to the list.

Add the following three PersonAddress objects to the list.

Write a C program to run on unix to read a text file and print it to the display. It should count of the number of words in the file, find the number of occurrences of a substring, and take all the words in the string and sort them (ASCII order). You must use getopt to parse the command line. There is no user input while this program is running.

Usage: mywords [-cs] [-f substring] filename

• The -c flag means to count the number of words in the file. A word would be a series of characters separated by spaces or punctuation. A word could include a hyphen or a single apostrophe.

• The -s option means to print the words in the file sorted by ASCII order.

• The -f option will find the number of occurrences of the given substring.

• You may have any number of the flags included or none of them.

• The order they should be run would be: -s first, -c second, and -f third.

--------------------------------------------------------------------------------

Format of parsing the command line (main method established), rest of functionality needed as explained above:

int value = 0;

int main(int argc, char **argv) {
    extern char *optarg;
    extern int optind;
    int c, err = 0;
    int cflag = 0, sflag = 0, fflag = 0;
    char *substring;

    // usage 
    static char usage[] = "usage: mywords [-cs] [-f substring] filename";  

    while ((c = getopt(argc, argv, "csf:")) != -1)
        switch (c) {
            case 'c':
                cflag = 1;
                break;

            case 's':
                sflag = 1;
                break;

            case 'f':
                fflag = 1;
                substring = optarg;
                break;

            case '?':
                err = 1;
                break;
        }

    if (fflag == 1) {
        printf("%c ", substring);
    }
}

Modify the MergeSort program given to support searching subarrays.

Program is listed below in Java.

public class Merge

{

public static void sort(Comparable[] a)

}

Comparable[] aux = new Comparable[a.length];

sort(a, aux, 0, a.length);

}

private static void sort(Comparable[] a, Comparable[] aux, int lo, int hi)

{ //Sort a[lo, hi)

if (hi - lo <= 1) return;

int mid = lo (hi + lo) / 2;

sort( a, aux, lo, mid);

sort(a, aux, mid, hi);

int i = lo, j = mid;

for (int k = lo; k < hi; k++)

if (i == mid) aux[k] = a[j++];

else if (j == hi) aux[k] = a[i++];

else if (a[j].compareTo(a[i]) < 0) aux[k] = a[j++];

else aux[k] = a[i++];

for (int k = lo; k < hi; k++)

a[k] = aux[k];

}

public static void main(String[] args)

{ }

}

Note: The user would give an unsorted list of words as command-line arguments along with the starting and ending index of the subarray that should be sorted. The program should print out a list where the strings between the given indexes are sorted alphabetically.

• Sample runs would be as follows.

>java MergeSort 2 4 toy apply sand bay cat dog fish

toy apply bay cat sand dog fish

>java MergeSort 0 3 was had him and you his the but

and had him was you his the but

Typed please.How can we implement efficient search operations? In this area, we will discuss various algorithms, including sequential search, sorted search, and binary search. The characteristics of these algorithms will be analyzed, such as the running times and the type of lists they can be used with.

Case study for chapter # 6 [page # 182]

Previous chapters have described the technological capabilities that Bill Wiley wants for servicing his customers. One of the problems that Bill has is that his company is very small, so he cannot afford to develop any special-purpose equipment or even sophisticated software.
Given this limitation, Bill’s need for advanced technological capabilities comes at an opportune time. Equipment manufacturers are developing equipment with advanced telecommunications capabilities, and freelance software developers are producing software applications—many of which provide the capabilities that Bill needs. The one caveat is that because this will be a live production system, it needs to be reliable, stable, error-free, dependable, and maintainable.
Let us review some of the required capabilities of the new system, which has been described in previous chapters:
Customers
■   Customers can request package pickup via the Internet.
■   Customers can check the status of packages via the Internet.
■   Customers can print mailing labels at their offices.
Drivers
■   Drivers can view their schedules via a portable digital device while on their routes.
■   Drivers can update the status of packages while on their routes.
■   Drivers can allow customers to “sign” for packages that are delivered.
they only plan to provide some design specifications and guidelines to each resort. The resort will be responsible for connecting to the Internet and for providing a secure wireless environment for the students.
1. For which subsystem(s) is(are) integrity and security controls most important? Why?
2. What data should be encrypted during trans- mission through resort wireless networks to SBRU systems? Does your answer change if students interact with SBRU systems using a cell phone (directly, or as a cellular modem)?
■   The system “knows” where the driver is on his route and can send updates in real time.
■   Drivers can accept payments and record them on the system.
Bill Wiley (management)
■   Bill can record package pickups from the ware- house.
■   Bill can schedule delivery/pickup runs. ■   Bill can do accounting, billing, etc. ■   Bill can access the company network from his
home. Given these requirements, do the following:

1. What kind of fraud is possible in this scenario? By the customer? By the truck driver? By colaboration between system users? What steps should Bill take to minimize the opportunity for fraud?

2. What kind of access controls should be put in place? For the customer? (Notice the customer has no financial transactions. Would you change your answer if the customer could also make payments online?) For the truck driver? For Bill? Are the typical userID and password sufficient for all three, or would you require more or less for each?

Polish notation, also known as Polish prefix notation or simply prefix notation, is a form of notation for logic, arithmetic, and algebra. Its distinguishing feature is that it places operators to the left of their operands.

The expression for adding the numbers 1 and 2, in prefix notation, is written as “+ 12” rather than “1 + 2”. In more complex expressions, the operands may be nontrivial expressions including operators of their own. For instance, the expression that would be written in conventional infix notation as (5 + 6) * 7 can be written in prefix as * (+ 5 6) 7

In this assignment, we only care about binary operators: + - * and /.

For binary operators, prefix representation is unambiguous and bracketing the prefix expression is unnecessary. As such, the previous expression can be further simplified to * + 5 6 7

The processing of the product is deferred until its two operands are available (i.e., 5 plus 6, then multiplies the result with 7). As with any notation, the innermost expressions are evaluated first, but in prefix notation this ”innermost-ness” is conveyed by order rather than bracketing.

Your task is to create a class that convert a prefix expression to a standard form (otherwise known as infix) and compute the prefix expression.

Main function

The test script will compile your code using

g++ -o main.out -std=c++11 -O2 -Wall *.cpp

It is your responsibility to ensure that your code compiles on the university system. g++ has too many versions, so being able to compile on your laptop does not guarantee that it compiles on the university system. You are encouraged to debug your code on a lab computer (or use SSH).

Create a main function that takes in one line. The line contains a list of operators and operands separated by spaces. The input doesn’t contain parenthesis. An operator is a character from +, -, *, and /. An operand is a nonnegative integer from 0 to 99. You are asked to convert the prefix expression to an infix form and output its value as well. If the expression is not a valid prefix expression, your program should output “Error”.

Sample input: * - 5 6 7

Sample output: (5 - 6) * 7 = -7

Sample input: * 5

Sample output: Error

Sample input: * 5 6 7

Sample output: Error

Please provide the .h, .cpp and main.cpp file for this, like Polish.h Polish.cpp and main.cpp thank you
