The highestOneBit() method is a method of Integer class under java.lang package. This method returns int value with at most a single one-bit, in the position of the highest-order ("leftmost") one-bit in the specified int value. If the specified value has no one-bits or is equal to zero in its two's complement binary representation, it returns zero.

Syntax:

Following is the declaration of highestOneBit() method:

Parameter:
