What is the output of the following code? “`java Integer a = 127; Integer b = 127; Integer c = 128; Integer d = 128; System.out.println(a == b); System.out.println(c == d); “`

Accepted Answer

The output of the code is "true, false" because for Integer values between -128 to 127, Java uses cached objects. So, a and b point to the same object, while c and d do not.
