public static void main(String args[])
{
ArrayList l = new ArrayList();
while (true)
{
String s = new String("This will fill up memory");
l.add(s);
}
}

An OutOfMemoryError will occur when the JVM tries to allocate memory (usually for a new
object) but there is not enough free memory in the heap *and* the heap cannot grow
because it has already reached its limit (set during the invocation of "java") *and*
garbage collection has not been able to free enough memory.
