Map使用 entrySet()遍历集合

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Set;

public class Test01 {

	public static void main(String[] args) {
		HashMap<String, String> hMap = new HashMap<>();
		hMap.put("欧欧", "雪纳瑞");
		hMap.put("亚亚", "拉布拉多");
		hMap.put("菲菲", "拉布拉多");
		hMap.put("美美", "雪纳瑞");
		System.out.println("使用Iterator和增强型for循环遍历所有狗狗的昵称和品种分别是:");
		Set<Map.Entry<String,String>> entry = hMap.entrySet();
		for (Iterator<Map.Entry<String,String>>  ite = entry.iterator();ite.hasNext();) {
			System.out.println(ite.next());
		}
		
	}
