Integer wrapper return true from range -128 to 127

We are already familiar with boxing and auto boxing of wrapper to premitives and vice-verse.

See the below example.

    Integer integer1=127;
    Integer integer2=127;

    System.out.println(integer1==integer2);//The output will be true.
   
But as we increase the value from 127 to 128 you will see the output is different.
   
    Integer integer1=128;
    Integer integer2=128;

    System.out.println(integer1==integer2);//The output will be False.

As per JLC the boxed value returns true for int or short in the range of -128 to 127(included). It also returns true for a byte or a char in the range of \u0000 to \u007f.
