1. Consider the following lines of coding written in Java, Your teacher went through similar type of example in the class to show some of the drawbacks of this type of programming, can you write those drawbacks. Also will this program compile? If not which lines you need to change, can you avoid those changes by using some technique taught in the class? 1- class Test { 3 private Object t; 4 public Object get() { return t; } 6. public void set(Object t) { this.t = t; } 10 11 12 } 13 14 - public class Main { public static void main(String args[]){ Test type = new Test(); type.set("Quiz 6"); String str = type.get(); type.set(6); int number= type.get(); System.out.println(str); System.out.println(number); 15- 16 17 18 19 20 21 22 23 24 } 2. Can you write down the Generic Class version of Test class written above with the driver class Main as well?
