So the reason why you are seeing an int as 4 bytes (32 bits), is because the code is compiled to be executed efficiently by a 32-bit CPU. If the same code were compiled for a 16-bit CPU the int may be 16 bits, and on a 64-bit CPU it may be 64 bits.
Why integer is 4 bytes in Java?
Its simple, when we initialize some variable of integer data type in program this allocate 4 bytes of space in memory. This means that 4 bytes of space (1byte=8bit) will be allocated for that particular variable in the memory.
Why is long 4 bytes?
According to the standard, someone could make long long 256 bits, and itβd be perfectly legal. The C++ Language Specification simply states that the size of a long must be at least the size of an int . It used to be standard to have int = 2 bytes and long = 4 bytes.
