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.
