new.java

看thinkinjava学习java时

package myutils;
import java.util.*;
public class New {

	public static <K,V> Map<K,V> map(){
		return new HashMap<K,V>();
	}
	public static <T> List<T> list(){
		return new ArrayList<T>();
	}
	public static <T> LinkedList<T> lList(){
		return new LinkedList();
	}
	public static <T> Set<T> set(){
		return new HashSet();
	}
	public static <T> Queue<T> queue(){
		return new LinkedList();
	}
	public static void main(String[] args) {
		Map<String,List<String>> sls = New.map();
		List<String> ls = New.list();
		LinkedList<String> lls = New.lList();
		Set<String> ss = New.set();
		Queue<String> qs = New.queue();
		
		 
		

	}
