 Write a program to design simple calculator  with the use of Grid Layout

Program Code

1. Write java Program to Demonstrate Grid of 5* 5

import java.awt.*;
/**

 */
public class programcode1 {
    programcode1()
    {
        Frame frame = new Frame();
        frame.setLayout(new GridLayout(5,5));
        for(int i = 1 ; i <= 25 ; i++)
        {
            frame.add(new Button(" "+i));
        }
        frame.setSize(500, 500);
        frame.setVisible(true);
    
    }
    public static void main(String args[]) 
    {
        programcode1 pc1 = new programcode1();       
    }
}

OUTPUT :

Write java Program to Demonstrate Grid of 5* 5

2. Write a program to display The Number on Button from 0 to 9.

import java.awt.*;
/**

 */
public class programcode2 {
    programcode2()
    {
        Frame frame = new Frame();
        frame.setLayout(new GridLayout(3,3));
        for(int i = 0 ; i <= 9 ; i++)
        {
            frame.add(new Button(" "+i));
        }
        frame.setSize(500, 500);
        frame.setVisible(true);
    
    }
    public static void main(String args[]) 
    {
        programcode2 pc2 = new programcode2();       
    }
}

OUTPUT :

Write a program to display The Number on Button from 0 to 9.
