<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);
}
}
public static void main(String[] args){ int[] testScores; testScores = new int[4]; printScores<int>(testScores); }Quote:Original post by Anonymous Poster
maybe you have to explicitly instantiate it?

not a statement.printScores<int>(testScores);; expectedprintScores<int>(testScores);Quote:Original post by SiCrane
Last time I checked, Java generics did not support primitive types, only things descended from Object. So no int.

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

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.
public class ArrayTest{ public static <T> void printScores(T[] scores){ for(T t : scores){ System.out.println(t); } } public static void main(String[] args){ Integer[] testScores = new Integer[4]; // you can populate the array with regular ints- they // will automatically be converted to Integer objects for(int i=0; i<4; ++i) testScores = i; printScores(testScores); } }Quote:Original post by Kevinator
Interesting find. Do you think that was intentional?
