OptionalLong toString() method in Java with examples

The toString() method help us to get a non-empty string representation of this OptionalLong.This non-empty string representation is suitable for debugging. The exact presentation format is unspecified and may vary between implementations and versions.

Syntax:

public String toString()

Parameters: This method accepts nothing.

Return value: This method returns the string representation of this instance.

Below programs illustrate toString() method:
Program 1:

// Java program to demonstrate 
// OptionalLong.toString() method 

import java.util.OptionalLong; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create a OptionalLong 

        OptionalLong opLong 

            = OptionalLong.of(21342536475643L); 

        // get value using toString 

        String value = opLong.toString(); 

        // print value 

        System.out.print("Value: " + value); 

    } 
}

Output:

Value: OptionalLong[21342536475643]

Program 2:

// Java program to demonstrate 
// OptionalLong.toString() method 

import java.util.OptionalLong; 

public class GFG { 

    public static void main(String[] args) 

    { 

        // create a empty OptionalLong 

        OptionalLong opLong 

            = OptionalLong.empty(); 

        // get value using toString 

        String value = opLong.toString(); 

        // print value 

        System.out.print("Value: " + value); 

    }
