ArrayList issue
Nov 25th, 2007, 7:40pm  
For this (normal, valid java code):

ArrayList foo = new ArrayList();
for (int i=0; i<100; i++)
{
 foo.add(i);
}

i get following compilation error:

Semantic Error: No applicable overload for a method with signature "add(int)" was found in type "java.util.ArrayList". Perhaps you wanted the overloaded version "boolean add(java.lang.Object $1);" instead?

How in the world can i fill the arrayList with integers?

You need to convert from int to Integer (The Object version of int)

Code:
foo.add(new Integer(i));
