class TwoGen<T, V> {
  T ob1;

  V ob2;

  TwoGen(T o1, V o2) {
    ob1 = o1;
    ob2 = o2;
  }

  void showTypes() {
    System.out.println("Type of T is " + ob1.getClass().getName());

    System.out.println("Type of V is " + ob2.getClass().getName());
  }

  T getob1() {
    return ob1;
  }

  V getob2() {
    return ob2;
  }
}

public class MainClass {
  public static void main(String args[]) {
    TwoGen<Integer, String> tgObj = new TwoGen<Integer, String>(88, "Generics");
    tgObj.showTypes();

    int v = tgObj.getob1();
    System.out.println("value: " + v);

    String str = tgObj.getob2();
    System.out.println("value: " + str);
  }
}

Type of T is java.lang.Integer
Type of V is java.lang.String
value: 88
value: Generics
