Question

Need help with Java, I was able to get this done half way but still very confusing afterwards.

for this class create an outer class called OuterCar with method called drive.

Create an inner class called InnerEngine with methods called start, stop and shift (all methods with simple print statements)

Call inner class methods called start, stop and shift from outer class drive method.

The solution will produce the following:

1. OuterCar class
2. OuterCar class with drive method
3. InnerEngine class
4. InnerEngine methods start, stop and shift
5. OuterCarTest class with main method

Answer 1

//OuterCar.java
public class OuterCar {
    // Instance variable
    InnerEngine innerEngine;

    // Constructor
    public OuterCar() {
        innerEngine = new InnerEngine();
    }

    // drive method
    void drive(){
        //Calling inner class methods called start, stop and shift
        innerEngine.stop();
        innerEngine.shift();
        innerEngine.stop();
    }

    private class InnerEngine {
        // start method
        void start(){
            System.out.println("Engine started");
        }

        // stop method
        void stop(){
            System.out.println("Engine stopped");
        }

        // shift method
        void shift(){
            System.out.println("Moving...");
        }
    }
}

//OuterCarTest.java
public class OuterCarTest {
    public static void main(String[] args) {
        OuterCar outerCar = new OuterCar();
        outerCar.drive();
    }
}

Engine stopped
Moving...
Engine stopped
