Java lang.Long.toBinaryString() method with Examples
The java.lang.Long.toBinaryString() method returns a string representation of the long argument as an unsigned integer in base 2.
Example
Following is an example to implement the toBinaryString() method −
import java.lang.*; public class Demo { public static void main(String[] args) { long l = 190; 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 = " } }
Output
Number = 190 Binary is 10111110 Number of one bits = 6
Example
Let us see another example wherein we are considering negative number −
import java.lang.*; public class Demo { public static void main(String[] args) { long l = -25; System.out.println("Number = " + l); System.out.println("Binary is " + Long.toBinaryString(l)); System.out.println("Number of one bits = " + Long.bitCount(l)); } }
Output
Number = -25 Binary is 1111111111111111111111111111111111111111111111111111111111100111 Number of one bits = 62
