Greetings , I am a newbie java learner , stepped from basic C knowlage
to java at my universty and sadly due to I was sick I missed the latest
course . I am seeking explaining about what this small program do and
how to complie it. When I try to complie it at terminal i am getting
"no suitable method `main' in class
" error.

    You compile a java program using "javac", and one of the ways to run the
program is using "java". If you get the error message "no suitable method
'main' in class", it means you've already compiled the program and are now
trying to run it.

As far as I understood it looks like it will show some
graphics and it is some kind of javaapplet.

Here is the code:
import java.awt.*;
import javax.swing.*;

public class PointArrayApplet extends JApplet
public void paint(Graphics g)
Point [] triangle;
triangle=new Point[3];
triangle[0]=new Point(10,20);
triangle[1]=new Point(35,90);
triangle[2]=new Point(75,105);
public static void translate(Point []points,int deltaX,int deltaY)
for(int i=0;i<points.length;i++)

Thanks in advance.

    The program you have here is an applet, as you've noted. The "java"
command can be used to run stand-alone java programs, but not applets. To
run the applet, you either need to embed it in an HTML page and view it
using your webbrowser, or use the "appletviewer" program.
