Singleton
Instructions
In this quest, we will implement some design patterns.
At first, we will implement the singleton pattern.
classDiagram
class Excalibur{
-String name
-Excalibur INSTANCE$
-Excalibur(String name)
+getName() String
+getInstance()$ Excalibur
}
Excalibur <-- Excalibur
Here is the matching class diagram. Create the matching class in the matching file.
When calling getInstance
method, an instance of Excalibur with name "Sword" should be returned.
Usage
Here is a possible ExerciseRunner.java to test your function :
public class ExerciseRunner {
public static void main(String[] args) {
System.out.println(Excalibur.getInstance().getName());
}
}
and its output :
$ javac *.java -d build
$ java -cp build ExerciseRunner
Sword
$
