Question

Write a Java program called Decision that includes a while loop to prompt the user to enter 5 marks using the
JOptionPane statement and a System.out statement to output a message inside the loop highlighting a pass
mark >= 50 and <= 100. Any other mark will output a messaging stating it’s a fail.
Example of the expected output is as follows:
55 is a pass
12 is a fail

Answer 1

Answer:

Written in Java

import javax.swing.JOptionPane;

public class Decision{

public static void main(String[] args) {

    int i = 1;

    while(i<=5){

    String score = JOptionPane.showInputDialog("Input <score>");

    int mark = Integer.parseInt(firstNumber);

    if(mark >= 50 && mark <= 100) {

        JOptionPane.showMessageDialog(null, mark, " is a pass", JOptionPane.PLAIN_MESSAGE);

    }

    else{

        JOptionPane.showMessageDialog(null, mark, " is a fail", JOptionPane.PLAIN_MESSAGE);

    }

    i++;

    }

}

}

Explanation:

This initializes the a counter variable i to 1

    int i = 1;

The following iteration is repeated as long as i is less than or equal to 5

    while(i<=5){

This prompts user for input

    String score = JOptionPane.showInputDialog("Input <score>");

This converts user input to integer

    int mark = Integer.parseInt(firstNumber);

This checks if input is within 50 and 100 (inclusive)

    if(mark >= 50 && mark <= 100) {

This prints pass

        JOptionPane.showMessageDialog(null, mark, " is a pass", JOptionPane.PLAIN_MESSAGE);

    }

If otherwise

    else{

This prints fail

        JOptionPane.showMessageDialog(null, mark, " is a fail", JOptionPane.PLAIN_MESSAGE);

    }

This increments the counter variable by 1

    i++;

    }
