JVM numeric types - Integer types

▤ Summary

Without understanding the representation of numbers used by computers, developers cannot anticipate the issues that may arise and avoid them. Things probably started with people making notches in sticks to represent numbers, but more advanced systems evolved. Those who have some familiarity with modular arithmetic assume that the operator on integers will always return a positive value. The JLS - Integer Literals allows you to write code using binary, octal, hexadecimal or decimal forms. Bytes and shorts are automatically widened to the int type when they are pushed onto the stack.
