The orElse(long) method helps us to get the value in this OptionalLong object. If a value is not present in this OptionalLong, then this method returns the value passed as the parameter.
Syntax:
public long orElse(long other)
Parameters: This method accepts long 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( long ) method:
Program 1:
Java
// Java program to demonstrate// OptionalLong.orElse(long) methodimport java.util.OptionalLong;public class GFG { public static void main(String[] args) { // create a OptionalLong OptionalLong opLong = OptionalLong.of(452146); // get value using orElse long value = opLong.orElse(13421); // print value System.out.println("value: " + value); }} |
Output:
value: 452146
Program 2:
Java
// Java program to demonstrate// OptionalLong.orElse(long) methodimport java.util.OptionalLong;public class GFG { public static void main(String[] args) { // create a OptionalLong OptionalLong opLong = OptionalLong.empty(); // get value using orElse long value = opLong.orElse(13421); // print value System.out.println("value: " + value); }} |
Output:
value: 13421
