What does the maximum value of a variable in Java depend on?

The maximum value of a variable in Java depends on its data type. Java has primitive types with fixed sizes and ranges:

• byte: 8 bits, from -128 to 127
• short: 16 bits, from -32768 to 32767
• int: 32 bits, from -2,147,483,648 to 2,147,483,647
• long: 64 bits, from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
• float and double — floating-point numbers, maximum values depend on the IEEE 754 standard

The maximum value is determined by the number of bits and the type's specification. For example, for int, it is 2^31 - 1, since one bit is used for the sign.
