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 (25500);
  g.fillRect (00, getWidth(), getHeight());
  g.setColor (00255);
  g.fillRect (203020080);
  g.setColor (1280255);
  g.drawLine (00100200);
  }
}
