Java Long.toHexString() Method

  • Last Updated : 05 Dec, 2018


The Java.lang.Long.toHexString() is a built-in function in Java which returns a string representation of the long argument as an unsigned integer in base 16. The function accepts a single parameter as an argument in Long data-type.

Syntax:

public static String toHexString(long num)

Parameters:  The function accepts a single mandatory parameter 
num -  This parameter specifies the number which is to be converted to Hexadecimal string. 

Return Value: The function returns a string representation of the long argument as an unsigned integer in base 16.

Examples:

Input : 11
Output : b

Input : 12
Output : c

Program 1: The program below demonstrates the working of function.






// Java program to demonstrate working
// of java.lang.Long.toHexString() method
import java.lang.Math;
  
class Gfg1 {
  
    // driver code
    public static void main(String args[])
    {
  
        long l = 11;
  
        // returns the string representation of the unsigned int value
        // represented by the argument in binary (base 2)
        System.out.println("Hex string is " + Long.toHexString(l));
    }
}

Output:

Hex string is b

Program 2: The program below demonstrates the working of function.




// Java program to demonstrate working
// of java.lang.Long.toHexString() method
import java.lang.Math;
  
class Gfg1 {
  
    // driver code
    public static void main(String args[])
    {
  
        long l = 234;
  
        // returns the string representation of the unsigned int value
        // represented by the argument in binary (base 2)
        System.out.println("Hex string is " + Long.toHexString(l));
    }
}

Output:

 Hex string is ea
