Advertisements


Description

The java.lang.Long.toBinaryString() method returns a string representation of the long argument as an unsigned integer in base 2.

Declaration

Following is the declaration for java.lang.Long.toBinaryString() method

public static String toBinaryString(long i)

Parameters

i − This is the long to be converted to a string.

Return Value

This method returns the string representation of the unsigned long value represented by the argument in binary (base 2).

Exception

NA

Example

The following example shows the usage of java.lang.Long.toBinaryString() method.

package com.tutorialspoint;

import java.lang.*;

public class LongDemo {

   public static void main(String[] args) {

      long l = 210;
      System.out.println("Number = " + l);

      /* returns the string representation of the unsigned long value 
         represented by the argument in binary (base 2) */
      System.out.println("Binary is " + Long.toBinaryString(l));

      // returns the number of one-bits 
      System.out.println("Number of one bits = " + Long.bitCount(l)); 
   } 
}  

Let us compile and run the above program, this will produce the following result −

Number = 210
Binary is 11010010
Number of one bits = 4
