JAVA PROGRAM TO GENERATE CONECNTRIC CIRCLES:
2007-07-11 11:39:00
In C++ to draw a circle on the screen, Radius of circle is used. But in Java to do the same task width of a circle and height of a circle is used. In C++ x and y coordinates are used for the center point of the circle but in JAVA x and y coordinates for top corner and left corner are used. So if we want to generate concentric circles in JAVA the following logic should be used.import java.awt.*;import java.applet.*;/**/public class appletdemo extends Applet{ public void paint(Graphics g) { try { for (int i=10;i { g.drawOval(200-i/2,200-i/2,i,i); Thread.sleep(100); // To generate a delay n miliseconds } } catch(Exception e) { } }};

How To Compile and Run a JAVA Program :
2007-07-09 12:24:00
Step 1: Type your JAVA Program into any text editor like notepad or Edit (Dos Based Editor).Step 2: Save your program (filename.java). You should use four characters extension .java just for examplehello.java.Step 3: Compile your program with the follwing command at dos promptwhere your java compiler exist. in my case c:jdk folder. So first of all you have to change the directoryc:> cd jdk c:jdk> cd bin c:jdkin> JAVAC hello.java Java c is a java compiler.if compilation is successfully done, it will create a hello.class file.If your program contains 3 classes then it automatically creates 3 .class file, each file for each classes.It is the file which contains byte code.To run a java programc:jdkin>java hellowhere java is a interpreter and hello is a .class file. And you are done. you have sucessfully compiled and runyour java program.
