generics problem

I am trying to learn generics but it gives me an error when I try to compile this code. It says

<T>printScores(T[]) in ArrayTest cannot be applied to (int[])
printScores(testScores);
^

public class ArrayTest{

public static <T> void printScores(T[] scores){
for(T t : scores){
System.out.println(t);
}
}

public static void main(String[] args){

int[] testScores;
testScores = new int[4];

printScores(testScores);

}

}

I know that I have a local array that doesn't have anything in it yet so I don't know if that's the problem or not, but I am sure it will be down the road. If anyone can help me I would appreciate it very much, Thanks.

The problem is an int[] is not a T[].

That's not going to work.

The entity between < and > must be the type variable(s) in the generic method.
 
I agree. Here's the link: http://aspose.com/file-tools
