java里的泛型程序设计

public class Pair<T> {
	private T first;
	private T second;
	public Pair(){first=null;second=null;}
	public Pair(T first,T second){this.first=first;this.second=second;}
	
	public T getFirst(){return first;}
	public T getSecond(){return second;}
	
	public void setFirst(T newValue){first=newValue;}
	public void setSecond(T newValue){second=newValue;}
	
}
