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
