Answer 1

Because the value of the Integers are the same, but they're not the same objects in memory. == compares the memory refence. You can compare the values with the valueOf method of Integer.

Answer 2

You're welcome.

Answer 3

But when the values assigned to Integer range from (-128 to 127)...
the == returns true ,when they are same.
