How to use getMethod() with primitive types?

Question

This is the class:

class Foo {
  public void bar(int a, Object b) {
  }
}

Now I'm trying to get "reflect" this method from the class:

Class c = Foo.class;
Class[] types = { ... }; // what should be here?
Method m = c.getMethod("bar", types);

Solution 1

There's just an int.class.

Class[] types = { int.class, Object.class };

An alternative is Integer.TYPE.

Class[] types = { Integer.TYPE, Object.class };

The same applies on other primitives.

Solution 2

The parameter of the method is a primitive short not an Object Short.

Reflection will not find the method because you specified an object short. The parameters in getMethod() have to match exactly.

EDIT: The question was changed. Initially, the question was to find a method that takes a single primitive short.

And how do you invoke the method? If I want to pass boolean to such a method it does not work: invoke(null, new Object[] {myString, myBool}); ... boolean cannot be converted to Object.

@Racky Works for me, at least syntactically. Are you using a Java version below 5 (missing Autoboxing)?
