My compiler is not working properly?

Every time I compile a code like this (recently)


class ArrayDemo {
public static void main(String[] args) {
// declares an array of integers length "size"
int[] anArray;
int i = 0;
int size = 10;
anArray = new int[size];

// initialize array
for(i=0; i<size; i++) {
anArray[i] = i*100;
}

for(i=0; i<size; i++) {
System.out.println("Element at index " + i + ": " + anArray[i]);
}
}
}

it gives me an "Hello World" message box, which I closed a long time ago. Any suggestion?

gives me an "Hello World" message box

well ... i guess there is a POSSIBILITY that it is actually calling a wrong memory address or something, but not likely AT ALL!!! ... restart the computer ? (assuming you are not running linux) and it should fix the problem....

Nope, still flashes an "Hello World"

what IDE are you using? if this were visual studio, it sounds exactly like you have the start project set to the wrong one, so when it does a build, it builds both and then runs the one that is set to run... since your hello-world most likely doesn't call your array demo it is never calling it. I have kept all of my Java projects separate, but I can try to help if you are running eclipse

I am using NetBeans IDE

Yeah I copied and pasted this into eclipse and it gave me the right output... Did you recently make a program that flashed "hello world"? Possibly just delete it if so. I use eclipse so I can't really give you and details on what to do with netbeans though
