JAVA MAP 遍历

方法一:

Map<String,String> map = new HashMap<String, String>();

for(Map.Entry<String, String> entry: map.entryset()) {
    String key = entry.getKey();
    String value = entry.getValue();
}

方法二:

for (Integer key : map.keySet()) {  

    System.out.println("Key = " + key);  

}  

//遍历map中的值  

for (Integer value : map.values()) {  

    System.out.println("Value = " + value);  

}
