遍历map的方式

Java代码：

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

public class MapShow {

	public static void main(String[] args) {
		Map<String, String> map = new HashMap<String, String>();
		map.put("a", "A");
		map.put("b", "B");
		map.put("c", "C");
		for (Entry<String, String> entry : map.entrySet()) {
			String strkey = entry.getKey();
			String strval = entry.getValue();
			System.out.println("键值对:" + entry + " " + "key:" + strkey + " "
					+ "value:" + strval);
		}
	}
}

输出结果：

键值对:b=B key:b value:B
键值对:c=C key:c value:C
键值对:a=A key:a value:A
