Java Long numberOfTrailingZeros(long i) method example 2018-02-16T07:26:12+00:00

java.lang.Long numberOfTrailingZeros(long i)

Description

The Long.numberOfTrailingZeros(long i) java method returns the number of zero bits following the lowest-order (“rightmost”) one-bit in the two’s complement binary representation of the specified long value. Returns 64 if the specified value has no one-bits in its two’s complement representation, in other words if it is equal to zero.

Make a note that the numberOfTrailingZeros() method of Long class is static thus it should be accessed statically which means the we would be calling this method in this format:

Long.numberOfTrailingZeros(method args)

Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java numberOfTrailingZeros method non statically.

Method Syntax

public static int numberOfTrailingZeros(long i)

Method Argument

Data Type Parameter Description
long i the value whose number of trailing zeros is to be computed

Method Returns

The numberOfTrailingZeros(long i) method of Long class returns the number of zero bits following the lowest-order (“rightmost”) one-bit in the two’s complement binary representation of the specified long value, or 64 if the value is equal to zero.

Compatibility

Requires Java 1.5 and up
