int to bytes code example

Example 1: convert int to byte python

pythonCopy>>> (258).to_bytes(2, byteorder="little")
b'\x02\x01'
>>> (258).to_bytes(2, byteorder="big")
b'\x01\x02'
>>> (258).to_bytes(4, byteorder="little", signed=True)
b'\x02\x01\x00\x00'
>>> (-258).to_bytes(4, byteorder="little", signed=True)
b'\xfe\xfe\xff\xff'

Example 2: int to byte

int i = 234;
byte b = (byte) i;
System.out.println(b); // -22
int i2 = b & 0xFF;
System.out.println(i2); // 234
