Create mobile application with J2ME : FillRoundRect

The rectangular shape is definitely an part of the canvas described through 4 corners , as being a rectangular shape that you could pull utilizing document as well as pen. You define a rectangle’s dimensions by identifying coordinates for the upper-left corner and the lower-right corner. Four types of rectangles can be drawn on a canvas.

They are a good layed out rectangular shape, stuffed rectangular shape, layed out rectangular shape along with curved edges, along with a stuffed rectangular shape along with rounded corners.

An outlined rectangle is one where only line segments connecting the corners are drawn. The inside of the rectangle remains the same color as the outside of the rectangle. 
FillRoundRect(int x, int y, int width, int height, int arcWidth, int arcHeight)
 Returns FillRoundRect by rounded rectangle 


example code :
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

/**
 * @author 1code
 */
public class fill extends MIDlet {
    private Write canvas;
     Display display;

    public void startApp() {
       display = Display.getDisplay(this);
       canvas = new Write(this);
       display.setCurrent(canvas);

    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }
}

class Write extends Canvas  {
     fill midlet;
    private final fill This;

    public Write(fill This) {
        this.midlet= midlet;
      this.This = This;
    }

    protected void paint(Graphics drwa) {
        drwa.setColor(255,255,255);  //the background
    drwa.fillRect(0,0,getWidth(),getHeight()); //fill background
drwa.setColor(0,0,255);
        drwa.fillRoundRect(getWidth()/5, getHeight()/4, getWidth()/6, getHeight()/2, 7, 10);

        drwa.setColor(254,0,255);
        drwa.fillRoundRect(getWidth()/2, getHeight()/4, getWidth()/6, getHeight()/4, 180, 360);
      
    }

Create mobile application with J2ME : line Canvas

Any canvas-based graphical user interface contains instances of the particular Canvas school inside of which usually the particular designer generates photos for instance people found in a  game. On this phase you’ll understand in regards to the Control class and stay released to be able to varieties. The canvas is divided into a virtual grid in which each cell represents one pixel. Coordinates mark the column and row of a cell within the grid . The x coordinate represents the column, and the y coordinate represents the cell’s row. The first cell located in the upper-left corner of the grid has the coordinate location of 0, 0, where the first zero is the x coordinate and the other zero is the y coordinate.

Low  lets coding , i will create simple line with canvas.
import the package ;
import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Graphics;
import javax.microedition.midlet.*;


Or import all package from icdui
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

Create Class

public class line extends MIDlet {
    private Write canvas;
     Display display;
    public void startApp() {
       display = Display.getDisplay(this);
       canvas = new Write(this);
       display.setCurrent(canvas);  
    }
    public void pauseApp() {
    }
    public void destroyApp(boolean unconditional) {
    }
}

Create class for drawing

class Write extends Canvas  {
     line midlet;
    private final line This;

    public Write(line This) {
        this.midlet= midlet;
      this.This = This;
    }

    protected void paint(Graphics drwa) {
        drwa.setColor(255,255,255);
    drwa.fillRect(0,0,getWidth(),getHeight());
        drwa.setColor(0,0,0);
        drwa.drawLine(getWidth(), getHeight(), 0, 0);
        drwa.setColor(255,0,0);
        drwa.drawLine(getWidth(), 0, 0, getHeight());

Open Source IDE : Eclipse

Eclipse is an open source community, whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle.

The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse projects and helps cultivate both an open source community and an ecosystem of complementary products and services.

Eclipse is often a multi-language software package development environment containing an integrated development environment (IDE) along with the extensible plug-in .  It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy and Scheme.



It can also be used to develop packages for the software Mathematica. The IDE is often called Eclipse ADT (Ada Development Toolkit) for Ada, Eclipse CDT for C/C++, Eclipse JDT for Java, and Eclipse PDT for PHP.

Eclipse was originally released under the Common Public License, but was later relicensed under the Eclipse Public License. The Free Software Foundation has said that both licenses are free software licenses, but are incompatible with the GNU General Public License (GPL). Mike Milinkovich, of the Eclipse Foundation commented that moving to the GPL would be considered when version 3 of the GPL was released.[

Java JFrame Basic Tutorial : Video

The Frame describes the visual interface (GUI) component which is a top level window with a title and a border. The Frame that is put in place like a JFrame item , will often possess adornments like a edge along with a name. Apart from which, the actual JFrame item additionally facilitates control keys items that are accustomed to near or even iconify the actual eye-port. The actual edge region that's contained in the general dimension from the frame could be determined while using getInsets technique. A minumum of one body is usually contained in the GUI dependent software.

Following are the constructors used in creating JFrame components:-
1) JFrame()

which creates a new frame that is initially invisible. 

2) JFrame(GraphicsConfiguration gc)

which  creates a Frame in the specified GraphicsConfiguration of a screen device with a blank title. 

3) JFrame(String title)

which   creates a new, initially invisible Frame with the specified title. 

4) JFrame(String title, GraphicsConfiguration gc)

which creates a JFrame with the specified title and the specified GraphicsConfiguration of a screen device. 

This is best video tutorial JFrame basic , all tutorial using eclipse.
