The orElse(double) method helps us to get the value in this OptionalDouble object. If a value is not present in this OptionalDouble, then this method returns the value passed as the parameter. Syntax:
public double orElse(double other)
Parameters: This method accepts double the value to be returned, if no value is present. Return value: This method returns the value, if present, otherwise other. Below programs illustrate toString() method: Program 1:
Java
import java.util.OptionalDouble;
public class GFG {
public static void main(String[] args)
{
OptionalDouble opDouble = OptionalDouble.of( 452146 );
double value = opDouble.orElse( 13421 );
System.out.println("value: " + value);
}
}
|
Program 2:
Java
import java.util.OptionalDouble;
public class GFG {
public static void main(String[] args)
{
OptionalDouble opDouble = OptionalDouble.empty();
double value = opDouble.orElse( 13421 );
System.out.println("value: " + value);
}
}
