Maximize a Frame using Swing

In this program, you will learn how to maximize a frame using setMaximizedBounds() to set the bounds for a maximized frame. Here is the source code :

import java.awt.*;
import javax.swing.*;

public class SwingSetBounds{
public static void main(String[] args){
JFrame frame = new JFrame();
Rectangle bounds = new Rectangle(0, 0, 500, 500);
frame.setMaximizedBounds(bounds);
frame.setSize(400, 400);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

Print Triangle using "*"

This example is for the beginners. If you want to draw a traingle using "*" then use the code given below to print star in triangle shape :

import java.io.*;

class startriangle{
public static void main(String[] args) {
try{
BufferedReader object = new BufferedReader(new InputStreamReader(System.in));
System.out.println("enter the number");
int a= Integer.parseInt(object.readLine());
for (int i=1; i<'a;i++ ){
for (int j=1; j<=i;j++ ){
System.out.print("*");
}
System.out.println("");
}
}
catch(Exception e){}
}
}
