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 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 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
