Tetris Game In JAVA


Welcome back guys sorry for the delay but I am back with the new project "Tetris Game" an old school, so here are the steps to create this game 

P.S.: Use Netbeans compiler

To download Netbeans click here

If you guys want to download this file click here

Steps 

1.) Create a new project and name it "Tetris".

2.) Create eight classes and name it "TetrisFrame","TetrisPanel","TetrisShape1","TetrisShape2","TetrisShape3","TetrisShape4","TetrisShape5" as shown in figure.



3.) Source Code for these classes is given below respectively.



For class TetrisFrame 


import java.awt.Color;
import java.awt.Dimension;
import java.awt.Toolkit;



import javax.swing.JFrame;



public class TretisFrame extends JFrame{
private static final long serialVersionUID = 1L;

public Dimension dim;
int locX;
int locY;
public TretisFrame() throws InterruptedException{
dim = Toolkit.getDefaultToolkit().getScreenSize();
locX=(int) dim.getWidth()*4/12;//this is to set the game into the center of the screen
locY=(int) dim.getHeight()*2/12;
pan = new TretisPanel();
this.setTitle("TretisFrame");
this.setSize(326,585);
this.setLocation(locX, locY);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setFocusable(true);
this.setResizable(false);
this.add(pan);
addKeyListener(pan);
}
public static void main(String[] args) throws InterruptedException{
new TretisFrame();
}
}
