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

java.lang.Long reverse(long i)


The Long.reverse(long i) java method returns the value obtained by reversing the order of the bits in the two’s complement binary representation of the specified long value.

Make a note that the reverse() 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.reverse(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 reverse method non statically.

Method Syntax
