1. 如果鍵值都要

for (Map.Entry<String, String> entry : map.entrySet()) {
	String key = entry.getKey();
	String value = entry.getValue();
	System.out.println("Key = " + key + ", Value = " + value);
}

2. 如果使用的語言版本低於java 5，或是打算在遍歷時刪除 條目

//使用泛型：
Iterator<Map.Entry<String, String>> iterator = map.entrySet().iterator();
	while (iterator.hasNext()) {
	Map.Entry<String, String> entry = iterator.next();
	String key = entry.getKey();
	String value = entry.getValue();
	System.out.println("Key = " + key + ", Value = " + value);
}
//不使用泛型：
Iterator iterator = map.entrySet().iterator();
while (iterator.hasNext()) {
	Map.Entry entry = (Map.Entry) iterator.next();
	String key = (String)entry.getKey();
	String value = (String)entry.getValue();
	System.out.println("Key = " + key + ", Value = " + value);
}
 

3. 如果僅需要鍵(keys)或值(values)

//遍歷map中的鍵
for (String key : map.keySet()) {
	System.out.println("Key = " + key );
}
//遍歷map中的值
for (String value : map.values()) {
	System.out.println("Value = " + value);
}
