Assignment Instructions: On Your Computer C Dr

Assignment Instructions Instructions: On your computer c: drive create a folder called myjava

Create a folder named myjava on your C: drive. Save the following Java code in a file called WhileLoopWithBreak.java inside the myjava directory. Make modifications to the code as specified below each commented section, then save the file. Open a command prompt, change directory to c:\myjava, compile the Java file with javac WhileLoopWithBreak.java, and run it using java WhileLoopWithBreak. Ensure the program runs without errors and fix any issues if they arise.

The program should implement a while loop with a condition that always evaluates to true. It should use a break statement to exit the loop when the user inputs zero. Test the program with user input, and ensure the loop exits appropriately on zero input. Save your Java code in jGRASP, then transfer it to c:\myjava and execute it from the command line.

Below is the skeleton code with placeholders for your modifications:

/ Name: Date: Notes: /


import java.util.Scanner;


class WhileLoopWithBreak {


public static void main(String[] args) {


int n;


Scanner input = new Scanner(System.in);


while (/ condition that is always true /) {


System.out.print("Enter a number (0 to exit): ");


n = input.nextInt();


if (/ user input is zero /) {


break; // exit the loop


}


// Additional processing can go here


}


input.close();


System.out.println("Loop exited.");


}


}

Ensure that you include the source code and the compiled .class files in the archive named W2_firstname_lastname.zip. Also, leave clear instructions in the submission explaining how to compile and run your program.

Paper For Above instruction

The objective of this assignment is to develop a simple Java program that demonstrates the use of a while loop with a break statement, controlled by user input. Specifically, the program continually prompts the user to enter a number and terminates the loop when the user inputs zero. This exercise reinforces the understanding of loop control mechanisms, user interaction, and basic Java syntax.

The core concept involves constructing an infinite loop, which in Java can be achieved by setting the while condition to true. Inside this loop, the program prompts the user to enter an integer. The program then evaluates whether the entered number is zero; if so, a break statement is executed to exit the loop immediately. Otherwise, it can process the input—such as displaying the number or performing other operations—and then reiterate.

Here's a detailed explanation of the components involved:

  • Infinite Loop: The loop runs perpetually unless explicitly broken. This is achieved through while (true).
  • User Input Handling: The Scanner class captures user input from the console. Validation or additional prompts can be incorporated as needed.
  • Break Statement: Acts as an exit condition when the user inputs zero. The break terminates the loop immediately, allowing the program to proceed with subsequent code.
  • Resource Management: Closing the Scanner object after input is best practice to avoid resource leaks.
  • Code Documentation: Including comments and structured output enhances clarity and usability.

Implementing this program serves as an introductory exercise in control flow, input/output handling, and debugging. By modifying the placeholders in the skeleton code, students learn to integrate logic, manage flow control, and develop robust Java applications.

Finally, the program's code should be saved in an integrated development environment like jGRASP, transferred to the specified directory, compiled, and executed from the command line as per instructions. The resulting archive should contain all relevant files, along with clear operational instructions, facilitating easy replication and testing of the program's functionality.
