WebDec 22, 2024 · For example, let's check whether the third bit is set in a byte value: byte val1 = 0b0110_0100; byte mask = 0b0000_0100; boolean isSet1 = (val1 & mask) > 0; assertTrue(isSet1); Here the binary number 01100100 is tested to see if the third bit – 00000100 is set by using bitwise AND. The result is greater than zero, so it is. WebThe output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &.

WebMethod-1: We can check whether kth bit of a number is set or not with the help of left shift operator. Algorithm: Firstly compute 1<< (k-1) and store it in a variable say var, hence var=1<< (k-1). var stores a number which has only its kth bit set. In this step you have to perform bitwise AND of number and var.
