create Class reference of Generic class

Question

I want to create class reference for Generic class .

I am having a generic class called GenericRtt coded as below:

package com.practice.rtt;

public class GenericRtt<T> {

    private T s;


    public T getS() {
        return s;
    }


    public void setS(T s) {
        this.s = s;
    }

}

I want to create reference not instance of the class as .
Class <GenericRtt<String>> generics=(Class<GenericRtt<String>>) GenericRtt.class;
I don't know how to create class reference of the GenericRtt.

What exactly would you be creating a reference to? – Nikki Jun 23 '13 at 06:59 — Nikki, Jun 23 '13 at 06:59
What exactly would you use this `generics` variable for? – newacct Jun 23 '13 at 23:08 — newacct, Jun 23 '13 at 23:08

You can't. The type of Class can only be the raw type.

The closest you can get is:

Class <GenericRtt> clazz = GenericRtt.class;

You can't. You should read about type erasure in Java

also this might be very helpful java-generic-class-determine-type

NO.

Even you have a reference ,Ultimately you have to create a object to use the reference.

GenericRtt rt = new GenericRtt();

Then you can assign it or refer to some declared reference ,I guess.
