java - how to use primitive types properly -

int x = 10; int y = 10;  integer x1 = new integer(10); integer y1 = new integer(10);  system.out.println(x == y); system.out.println(x1 == y1); 

the first sop print true whereas second 1 print false. actual problem ?

the second approach not checking values rather objects.

if want compare values of 2 integer objects have use appropriate methods compareto(integer)

like mentioned in comments if want check equality can use equals
