Last Updated : 17 Mar 2025

The lowestOneBit() method is a method of Integer class under java.lang package. This method returns int value with at most a single one-bit, in the position of the lowest-order ("rightmost") one-bit in the specified int value. If the specified value has no one-bits or is equal to zero in its two's complement binary representation, it returns zero.

Syntax:

Following is the declaration of lowestOneBit() method:

Parameter:

DataType	Parameter	Description	Required/Optional
int	i	It accepts integer type parameter whose lowest 1?s bit integer value is to be returned.	Required

Returns:

The lowestOneBit() method returns an int value with a single one-bit, in the position of the lowest-order one-bit in the specified value, or zero if the specified value is itself equal to zero.

Exceptions:

Compatibility Version:

Java 1.5 and above

Example 1

Output:

Integer value in the position of the lowest-order one-bit: 4

Example 2

Output:

Enter the desired value: 456
Integer value in the position of the lowest-order one-bit: 8

Example 3

Output:

Input Number is: 25
Lowhest 1-bit of the given integer is: 1

Lowest one bit of the given integer is = 4

Example 4

Output:

Input Number: 104
Binary Equivalent: 1101000
Total Number of 1-bits: 3
Integer Value of lowest 1-bit: 8
