Draw Line in J2me

     

In this example we are going to show you how to draw a line using J2ME. Please go through the below given J2ME syntax that includes all the package, methods and class to draw a line. 

Basically in J2ME, Canvas class is used to draw circle or line.. that is the only reason of using this canvas class in our J2ME program. We have also created a MIDlet called DrawLine in our application as we can't draw a line without creating it. 

g.drawLine(x, y, x+w, y);
g.drawLine(x+w, y, x+w, y+h); 
g.drawLine(x+w, y+h, x, y+h); 
g.drawLine(x, y+h, x, y);

or the another variation is: 

g.drawLine(x1, y1, x2, y2);

The above variation show the distance from x-axis and y-axis. 

The Application look like as follows:

 

DrawLine.java

import javax.microedition.midlet.*; import javax.microedition.lcdui.*; public class DrawLine extends MIDlet{   private Display display;   public void startApp(){   display = Display.getDisplay(this);   display.setCurrent (new DrawingCanvas());    }   public void pauseApp(){}   public void destroyApp (boolean forced){} } class DrawingCanvas extends Canvas{   public void paint (Graphics g){   g.setColor (255, 0, 0);   g.fillRect (0, 0, getWidth(), getHeight());   g.setColor (0, 0, 255);   g.fillRect (20, 30, 200, 80);   g.setColor (128, 0, 255);   g.drawLine (0, 0, 100, 200);   } }
