class test12 {

int x,y;

public void show(int xx,int yy)


public class test1 extends Applet
public void init ()

test12 labelbh[]=new test12[4];


Null Pointer exception is thrown when I try to access a member function of test12
I am trying to create an array of objects
Thanks in Advance

Welcome to the Ranch Bharathi!

arrays whose elements are of reference type are initialized to null. Initialize one of the elements of the array with something like labelbh[0] = new test12();

Notice we have a beginner's forum that seems more suitable for this question. This one is devoted to IO and streams.

SCJP2. Please Indent your code using UBB Code

As per Jose's suggestion, moving to Java in General (Beginner).
