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
