The Cosmic Superclass Every Java class you’ve ever written isautomatically a subclass of java.lang.Object. This means thatpublic methods from Object are inherited by your classes, and youmay override them. Several of these methods have signficantimplications, and we will concern ourselves with 2 of them:toString() and equals(Object other) To start Write a Student classthat has two instance variables: String name and int age. Write amain method that constructs such an object, sets the instancevariables, and then prints out the object. Something like this:Student s = new Student ( " Brian " , 22); System . out . println (" Student : " + s ); What does it print out? toString() WheneverJava needs to treat an object like a String, whether that be toprint out the object, or to use it to build up text (such as in theprevious example), it automatically calls the toString method toget the appropriate value. This works because every object has thismethod! You can override the method to change the Stringrepresentation for your custom objects. 1 Turn in a class thatloads an ArrayList with Student objects and prints out the entirelist: ArrayList < Student > students = new ArrayList (); students . add ( new Student ( " Brian " , 22));students . add ( new Student ( " Sandy " , 28)); System . out .println ( students ); What do you think is going on here?equals(Object other) Another method that all objects have isboolean equals(Object other). This method exists so that thedesigner of a new class can decide what makes two objects equal.Write a main method that creates two Student objects with the sameinstance variables. Are they equal? Should they be? Student s1 =new Student (" Craig " , 40); Student s2 = new Student (" Craig " ,40); if ( s1 == s2 ) { System . out . println ( " They are the same" ); } Hey, that’s never going to work! The equals operator (==)never looks at the contents of the objects it’s comparing. (That’swhy you shouldn’t use == to compare String objects) What does ==actually compare? Student s1 = new Student (" Craig " , 40);Student s2 = new Student (" Craig " , 40); if ( s1 . equals ( s2 )){ System . out . println ( " They are the same " ); } 2 Turn in aversion of the Student class that overrides equals to make theabove work as expected. Make sure to look at the javadocs forObject.equals to make sure you know how it should work
