Java Integer numberOfTrailingZeros() method

The numberOfTrailingZeros()  method of Java Integer class returns the total number of zero bits following the lowest-order one-bit in the 2’s complement binary representation of the specified int value. Syntax public static int numberOfTrailingZeros (int i) Parameters The parameter ‘i’ represents a value whose number of trailing zeros is to be determined. Return Value This method returns:

• The Number of zero bits following the lowest-order one-bit in the 2’s complement binary representation.
• 32 if the value is equal to zero.

Example 1

public class JavaIntegerNumberOfTrailingZerosExample2 {
    public static void main(String[] args) {
        Integer val1=76;
        //returns the Number of zero bits following the lowest-order one-bit in the 2’s complement binary representation
        int i= Integer.numberOfTrailingZeros(val1);
        System.out.println("Number of trailing zeros returned : "+i);
    }
}

Output

Number of trailing zeros returned : 2

Example 2

public class JavaIntegerNumberOfTrailingZerosExample2 {
    public static void main(String[] args) {
        Integer val1=0;
        //returns 32 if the value is equal to zero
        int i= Integer.numberOfTrailingZeros(val1);
        System.out.println("Number of trailing zeros returned : "+i);
    }
}

Output

Number of trailing zeros returned : 32

Example 3

public class JavaIntegerNumberOfTrailingZerosExample3 {
    public static void main(String[] args) {
        Integer val1=Integer.MIN_VALUE;
        int i= Integer.numberOfTrailingZeros(val1);
        System.out.println("Number of trailing zeros returned : "+i);
    }
}

Output

Number of trailing zeros returned : 31
