Java Integer numberOfTrailingZeros() Method

The numberOfTrailingZeros() method is a method of Integer class under java.lang package. This method returns the total number of zero bits following the lowest-order ("rightmost") one's-bit in the two's complement binary representation of the specified integer value i.e. it converts int value to Binary then considers the right-most one bit and return total number of zero bits following it. In other words, if the specified integer value has no one-bits or is equal to zero in its two's complement representation then it will return 32.

Exaplanation:

Syntax:

Following is the declaration of numberOfTrailingZeros() method:

Parameter:

DataType Parameter Description Required/Optional
int i It accepts integer value which returns lowest order bit on its 2's complement. Required

Returns:

The numberOfTrailingZeros() method returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of the specified integer value, or 32 if the value is equal to zero.
