Depends how left shift is implemented: on some processors (including x86), only the lowest order bits of the number of positions to shift by are used. In Java:

Depends how left shift is implemented: on some processors (including x86), only the lowest order bits of the number of positions to shift by are used. In Java: char A = 1; A = ((char) ((A << 32) & 0xFFFF)); System.out.println(Integer.toHexString(A)); actually outputs 1.
