Calling methods from an array

Question

Is there a way in Java to call methods from an array? I want to design a primitive board game and I would like to use an array of methods to represent the game spaces.

Answer 1

This is the basic idea (Command pattern)

static Runnable[] methods = new Runnable[10];

public static void main(String[] args) throws Exception {
    methods[0] = new Runnable() {
        @Override
        public void run() {
            System.out.println("method-0");
        }
    };
    methods[1] = new Runnable() {
        @Override
        public void run() {
            System.out.println("method-1");
        }
    };
    ...
    methods[1].run();
}

output

method-1

or with reflection

static Method[] methods = new Method[10];

public static void method1() {
    System.out.println("method-1");
}

public static void method2() {
    System.out.println("method-2");
}

public static void main(String[] args) throws Exception {
    methods[0] = Test1.class.getDeclaredMethod("method1");
    methods[1] = Test1.class.getDeclaredMethod("method2");
    methods[1].invoke(null);
}
