Java exponent error at 2^31 power [duplicate]

Answer 1

In general,

byte 8 bits, short 16 bits, int 32 bits, long 64 bits

For Integer(int) you can store a value in between -2^31 and 2^31 i.e., from -2,147,483,648 to 2,147,483,647

If you really want to calculate powers of 2 without any limitations (atleast as per theory), you can use strings and make multiplications accordingly.

Edit:

As Commusoft suggested, BigIntegers can also be used which improves performance over Strings.
