Java如何遍历HashMap呢?

实现思路:
    方式1：
	   使用while循环

	方式2:
	   使用for循环

package com.java265.other;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

public class test {
	/*
	 * java265.com 定义HashMap的示例分享
	 */
	public static void main(String[] args) {
		HashMap<String, String> m = new HashMap<>();
		m.put("name", "java265.com");
		m.put("other", "Java教程");

		System.out.println("=========方式1==========");
		// 方式1
		Iterator t = m.entrySet().iterator();
		while (t.hasNext()) {
			Map.Entry<String, String> a = (Map.Entry) t.next();
			System.out.println(a.getKey() + " = " + a.getValue());
		}

		System.out.println("=========方式2==========");
		// 方式2
		for (String k : m.keySet()) {
			System.out.println(k);
		}

		for (String v : m.values()) {
			System.out.println(v);
		}

		System.out.println("=========方式3==========");
		for (Map.Entry<String, String> entry : m.entrySet()) {
			String key = entry.getKey();
			Object value = entry.getValue();
			System.out.println("key:" + key + " value:" + value);
		}
	}
}
