Java Long class toHexString() method with example

Long class toHexString() method: Here, we are going to learn about the toHexString() method of Long class with its syntax and example. By Preeti Jain Last updated : March 20, 2024

Long class toHexString() method

  • toHexString() method is available in java.lang package.
  • toHexString() method is used to represent a hexadecimal string of the given parameter [value] of long type as an unsigned long in base 16.
  • toHexString() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
  • toHexString() method does not throw an exception at the time of conversion from long integer to Hexadecimal string.

Syntax

    public static String toHexString (long value);

Parameters

  • long value – represents the long value to be converted.

Return Value

The return type of this method is String, it returns the hexadecimal string of the given parameter that represent the unsigned long value.

Example

// Java program to demonstrate the example 
// of toHexString (long value) method of Long class

public class ToHexStringOfLongClass {
    public static void main(String[] args) {
        // Variables initialization
        long l1 = 10;
        long l2 = 20;
        long l3 = 30;
        long l4 = Long.MAX_VALUE;
        long l5 = Long.MIN_VALUE;

        // Long instance creation
        Long value = new Long(l1);

        // It represents hexadecimal string of the given
        // long type l2 argument
        String s = value.toHexString(l2);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(l2): " + s);

        // It represents hexadecimal string of the given
        // long type l3 argument
        s = value.toHexString(l3);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(l3): " + s);

        // It represents hexadecimal string of the given
        // long type l4 argument
        s = value.toHexString(l4);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(l4): " + s);

        // It represents hexadecimal string of the given
        // long type l5 argument
        s = value.toHexString(l5);

        // Display Hexadecimal String Representation
        System.out.println("value.toHexString(l5): " + s);
    }
}

Output

value.toHexString(l2): 14
value.toHexString(l3): 1e
value.toHexString(l4): 7fffffffffffffff
value.toHexString(l5): 8000000000000000
