How can I check if 2 "primitives" point to same value in Java.. For example for Objects, we can do it like

String a = "Xyz"; 
String b = "Abc";
boolean d = a == b; // == wont work for primitives!

Basically, I want to check for pass by reference in Java as follows ..

Integer b = sc.nextInt();
test(b); // Calling test method by passing int b;
static void test(int a){
// Check if a and b points to same value
}
