Good Evening Mr. Ansh
Java uses four integer types and they all are signed, positive and negative values. Java does not support unsigned, positive-only integers because unsigned integers are not necessary in Java.
The concept of unsigned was used in C/C++ to specify the behavior of high-order bit, which defined the sign of an integer when expressed as number.
It's simple, Java manages the meaning of the high-order bit differently by adding a special unsigned right shift operator, therefore there's no need to have an unsigned integer.
