a. After the introduction of classes, in a java class, Adongo a student of the class came out with the code below. Salamatu, a student of the class said adongo’s code was full of mistakes. Explain why salamatu made that statement class Abelewas { void bankudade(); int fabewoso(); double AttaaAyi(int x); } class pepper extends Abelewas{ public static void main(String potatoes[]) { peper ending = new bankudade(); } } b. Correct the code in “a” without introducing a new class and create an instantiation of the pepper class with an object variable called bankueba. Using bankueba, initialize the methods in the Abelewas class. c. Oforiwaa a student of the java class also produced the code below in a class discussion. Salamatu, again said that Oforiwaa’s code was incomplete and was seconded by Joshua another student of the class. Correct the code without changing the access type of the variables salary, name and pension. Using the object variable shito, initialize the variables salary, name and pension to 2000, Joshua Adamson and 120 respectively. Insert a code to display salary, name and pension. package wednesdayClass; class Wuntumi{ private double salary; private String name; private float pension; } public class Sowh3 extends Wuntumi { public static void main(String footbal[]) { Wuntumi sobolo = new Wuntumi(); } } d. Explain why the code was incorrect.
