Example of Drawing a Line and Rectangle in Java using AWT Components

Here is an example of  Java Program Drawing a Line in using AWT abstract Windows Toolkit and it's components

Draw a line
void drawLine(int startX, int startY, int endX, int endY)
drawLine( ) displays a line in the current drawing color that begins at startX,startY and ends    at endX,endY

import java.awt.*;
public class DrawLine extends Frame {
   public void paint(Graphics g) {
g.drawLine(0, 0, 100, 100);
g.drawLine(0, 100, 100, 0);
g.drawLine(40, 25, 250, 180);
g.drawLine(75, 90, 400, 400);
g.drawLine(20, 150, 400, 40);
g.drawLine(5, 290, 80, 19);   }       
  public static void main(String args[])   {
      DrawLine frame = new DrawLine();           
      frame.setSize(400, 400);
      frame.setVisible(true);   }}

Here is an example of  Java Program to Draw a rectangle  in using AWT abstract Windows Toolkit and it's components

if you want to draw a rectangle in output of java programming language use this java program

Draw a Rectangle 

—import java.awt.*;

—

—public class DrawRectangle extends Frame {

—   public void paint(Graphics g) {

—g.drawRect(10, 10, 60, 50);

—g.fillRect(100, 10, 60, 50);

—g.drawRoundRect(190, 10, 60, 50, 15, 15);

—g.fillRoundRect(70, 90, 140, 100, 30, 40);

—  }        

—  public static void main(String args[])

—  {

—      DrawRectangle frame = new DrawRectangle();           

—      frame.setSize(400, 400);

—      frame.setVisible(true);

—   }
