Question

Copy the the code below into your IDE or an online compiler and test an additional type with the generic class. Submit your code and execution display. IN JAVA

// A Simple Java program to show working of user defined

// Generic classes

   

// We use < > to specify Parameter type

class Test<T>

{

    // An object of type T is declared

    T obj;

    Test(T obj) {  this.obj = obj;  }  // constructor

    public T getObject()  { return this.obj; }

}

// Driver class to test above

public class Main

{

    public static void main (String[] args)

    {

        // instance of Integer type

        Test <Integer> iObj = new Test<Integer>(22);

        System.out.println(iObj.getObject());

   

        // instance of String type

        Test <String> sObj =

                          new Test<String>("Print this string");

        System.out.println(sObj.getObject());

    }

}

class Test<T>

{

// An object of type T is declared

T obj;

Test(T obj) { this.obj = obj; } // constructor

public T getObject() { return this.obj; }

public class Main

public static void main (String[] args)

{

// instance of Integer type

Test <Integer> iObj = new Test<Integer>(22);

System.out.println(iObj.getObject());

// instance of String type

Test <String> sObj =

new Test<String>("Print this string");

System.out.println(sObj.getObject());

Test <Double> dObj = new Test<Double>(22342.5);

System.out.println(dObj.getObject());

}
