Question

I have a method like this:

public static <T> boolean isMemberOf(T item, T[] set) {     for (T t : set) {         if (t.equals(item)) {             return true;         }     }     return false; } 

Now I try to call this method using a char for T:

char ch = 'a'; char[] chars = new char[] { 'a', 'b', 'c' }; boolean member = isMemberOf(ch, chars); 

This doesn’t work. I would expect the char and char[] to get autoboxed to Character and Character[], but that doesn’t seem to happen.

Any insights?

There is no autoboxing for arrays, only for primitives. I believe this is your problem.
