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);  }
