A simple Generics example.


class GenDemo

{ public static void main(String a[])

{ // Create a Gen reference for integers

Gen<Integer> iob;

iob.showType();

int v=iob.getob();

System.out.println("value: "+v);

Gen<String> strob = newGen<String>("Generics Test");

strob.showType();

String str= strob.getob();

System.out.println("value: "+ str);

}

}

class Gen<T>

{T ob;

Gen(T o)

{ob=o;

}

T getob()

{return ob;

}

void showType()

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

}
}
