The problem is, you can't.
Unles you name temp something else, and in this case, there really
isn't any reason not to.

import java.util.List;
import java.util.Map;

public class T {

public void tempString(List<String> str) {
}

public void tempInteger(List<Integer> str) {
}

public void tempMap(List<Map<String, Integer>> str) {
}
}
