OptionalInt orElse(int) method in Java with examples

The orElse(int) method helps us to get the value in this OptionalInt object. If a value is not present in this OptionalInt, then this method returns the value passed as the parameter. 

Syntax:

public int orElse(int other)

Parameters: This method accepts int the value to be returned, if no value is present. 

Return value: This method returns the value, if present, otherwise other. 

Below programs illustrate orElse() method: 

Program 1:

Java

// Java program to demonstrate
// OptionalInt.orElse(int) method

import java.util.OptionalInt;

public class GFG {

    public static void main(String[] args)
    {

        // create a OptionalInt
        OptionalInt opInt = OptionalInt.of(452146);

        // get value using orElse
        int value = opInt.orElse(13421);

        // print value
        System.out.println("value: " + value);
    }
}

Output:

value: 452146

Program 2:

Java

// Java program to demonstrate
// OptionalInt.orElse(int) method

import java.util.OptionalInt;

public class GFG {

    public static void main(String[] args)
    {

        // create a OptionalInt
        OptionalInt opInt = OptionalInt.empty();

        // get value using orElse
        int value = opInt.orElse(13421);

        // print value
        System.out.println("value: " + value);
    }
}

Output:

value: 13421
