Why 2147483647 and not 2147483648?

[Java] Where do the numbers -2147483648 to 2147483647 come from? They originate from the size of the data type. A byte has 8 bits - the valid range signed is -128 to +127 - altogether 256 different values (don't forget to count "0" as number as well). The max number of different values possible with 8 bits is 256 (2⁸).

2,147,483,647: The story behind this special number

Why is 2147483648 max?

Can 4 bytes store numbers between and 2147483647?

The storage of INTEGER variables is based on 4 bytes of signed data ( = 32 bits ). The value range is from -2,147,483,647 to +2,147,483,647. When assigning a whole number that exceeds the INTEGER range, the overflow error -1215 will be raised.

What is the largest int in Java?

The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Why those numbers? Integers in Java are represented in 2's complement binary and each integer gets 32 bits of space. In 32 bits of space with one bit used to represent the sign you can represent that many values.
