static <T> void f(T x){ System.out.println(1); } This is a generic method. It will take any type, including implicitly wrapped primitive types. So this method will match the call of f(i) and will shadow the other method that takes an int for a parameter.

Integer store references to Integer objects, just as with any other reference (object) type. And in your program it accepts a parameter of primitive type. in the second function your are passing an object of integer class and Java handles this with generics and gives output 1
