Java Long highestOneBit(long i) method example 2018-02-16T07:26:13+00:00

java.lang.Long highestOneBit(long i)


The Long.highestOneBit(long i) java method returns a long value with at most a single one-bit, in the position of the highest-order (“leftmost”) one-bit in the specified long value. Returns zero if the specified value has no one-bits in its two’s complement binary representation, that is, if it is equal to zero.

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