Long class lowestOneBit() method

  • lowestOneBit() method is available in java.lang package.
  • lowestOneBit() method is used to find at most only single 1’s bit from the rightmost side one bit in the path of the lowest order of the given parameter [value] of long type.
  • lowestOneBit() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
  • lowestOneBit() method does not throw an exception at the time of determining the lowest order bit in a single digit.

Syntax:

    public static long lowestOneBit (long value);

Parameter(s):

  • long value – represents the long value to be parsed.

Return value:

The return type of this method is long, it returns the long value based on the following cases,

  • it returns at most only single 1’s bit in the path of rightmost side one bit of the given long value.
  • Else, if the given argument is zero then, it returns the value 0.

Example:

// Java program to demonstrate the example 
// of lowestOneBit (long value) method of Long class

public class LowestOneBitOfLongClass {
    public static void main(String[] args) {
        long value = 1296;

        // It returns the string representation of the given unsigned 
        // long value denoted by the argument in binary by calling
        // Long.toBinaryString(value)
        System.out.println("Long.toBinaryString(value): " + Long.toBinaryString(value));

        // It returns the number with atmost 1's bits in the path of rightmost side 
        // one bit in the given argument 'value' by calling Long.lowestOneBit(value)
        System.out.println("Long.lowestOneBit(value): " + Long.lowestOneBit(value));
    }
}

Output

Long.toBinaryString(value): 10100010000
Long.lowestOneBit(value): 16
