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:

Answer 1

import javax.swing.*;
public class InputDemo
{
  public static void main(String args[])
  {
    int n = 0;
    while(n<5){
      String str1 = JOptionPane.showInputDialog("Enter Marks");
      double marks = Double.parseDouble(str1);
      if(marks>=50 && marks<=100){
        System.out.println("Marks:"+marks+" Status:Pass");
      }else{
        System.out.println("Marks:"+marks+" Status:Fail");
      }
      n++;
    }
  }
}

Output

C:\Users\shrikanth\Desktop>java InputDemo
Marks:34.0 Status:Fail
Marks:67.0 Status:Pass
Marks:50.0 Status:Pass
Marks:49.0 Status:Fail
Marks:100.0 Status:Pass

The output format is not given so I took it as Marks:__ Status:__

Have a good day.
