A simple generic class.

   
class Gen<T> {
  T ob; // declare an object of type T

    ob = o;
  }

  T getob() {
    return ob;
  }

  void showType() {
    System.out.println("Type of T is " + ob.getClass().getName());
  }
}

public class GenDemo {
  public static void main(String args[]) {
    Gen<Integer> iOb;
    iOb = new Gen<Integer>(88);

    iOb.showType();

    int v = iOb.getob();
    System.out.println("value: " + v);

    System.out.println();

    Gen<String> strOb = new Gen<String>("Generics Test");

    strOb.showType();

    String str = strOb.getob();
    System.out.println("value: " + str);
