Java how to call method by reflection with primitive types as arguments

Question

I have the following two methods in a class:

public void Test(int i){     System.out.println("1"); } public void Test(Integer i){     System.out.println("2"); } 

The following line of code

this.getClass().getMethod("Test",Integer.class).invoke(this, 10); 

prints 2 , how to make it print 1?

Answer 1

To call a method with primitive types as parameters using reflection :

You could use int.class

this.getClass().getMethod("Test",int.class).invoke(this, 10); 

or Integer.TYPE

this.getClass().getMethod("Test",Integer.TYPE).invoke(this, 10); 

same applies for other primitive types

Answer 2

Strange but true:

this.getClass().getMethod("Test",int.class).invoke(this, 10);
