Hi,

I have a doubt in Generics in the line marked 1
public class Box<T> {

private T t; //line 1

public void add(T t) {
this.t = t;
}

public T get() {
return t;
}

public static void main(String[] args) {
Box<Integer> integerBox = new Box<Integer>();
Box<String> stringBox = new Box<String>();

integerBox.add(new Integer(10));
stringBox.add(new String("Hello World"));

System.out.printf("Integer Value :%d\n\n", integerBox.get());
System.out.printf("String Value :%s\n", stringBox.get());
}
}

Can you explain what line 1 mean?
I understand that T is the type parameter.

Thanks.
