18.13.1.A simple generic class

T is a type parameter that will be replaced by a real type when an object of type Gen is created.

using System; 
 
class Gen<T> 
  T ob;
   
  public Gen(T o) { 
    ob = o; 
  
 
  public T getob() { 
    return ob; 
  
 
  public void showType() { 
    Console.WriteLine("Type of T is " + typeof(T))
  

 
class MainClass 
  public static void Main() { 
    Gen<int> iOb = new Gen<int>(102)
    iOb.showType()
 
    int v = iOb.getob()
    Console.WriteLine("value: " + v)
 
    Console.WriteLine()
 
    Gen<string> strOb = new Gen<string>("Generics add power.")
    strOb.showType()
    string str = strOb.getob()
    Console.WriteLine("value: " + str)
