engine.java

* Design a class named Car in package P1, having registration number, model and engine as its private members. Here engine is an object of a class called Engine in package P2 with the private members: chassis number and make. Define a suitable constructor of Car and override toString() method to print the details of a car. Assume appropriate data types for the instance members of the classes. Write a Java program to test the above class. */
