Answer 1

Code:

import javax.swing.*;  // import swing library

// declare a class
public class Main {  
JFrame f;
Main(){
  int count=5;
  f=new JFrame(); // create an object

// display dialogue box
  JOptionPane.showMessageDialog(f,"Enter 5 marks.");

  while(count-- > 0){
    String mark =JOptionPane.showInputDialog(f,"Enter mark: ");
    int a = Integer.parseInt(mark);
    if(a>=50 && a<=100){
      System.out.print("\nPass!");
    }else{
      System.out.println("\nFail!");
    }
  }
}

public static void main(String[] args) {  
    new Main();
  }  
}
