and seems that it does value comparison with one Integer and one constant.

Integer a1 = 1000;
Integer a2 = 1000;
Integer a3 = a1;
Integer b1 = 10;  // Less than 128 so Integer is cached.
Integer b2 = 10;

System.out.println("1000 is " + (a1 == a2));
System.out.println("10 is " + (b1 == b2));

System.out.println("1000 != is " + (a1 != a3));
