Program to produce OutOfMemoryError in Java

The below program produced the 'java.lang.OutOfMemoryError' in couple of seconds when i ran in my machine. :-)

public class OutOfMemory {

static int count = 0;

static ArrayList aString = new ArrayList();

static String string;

public static void main(String[] args) {

while (true){

int i=0;

string = new String("Achyuth");

aString.add(string);

aString.addAll(aString);

System.out.println(count++ +" "+aString.size());

}

}

}
