这篇文章主要介绍了java集合map取key使用示例,需要的朋友可以参考下

复制代码 代码如下:

for (Iterator i = keys.iterator(); i.hasNext()

       {

           String key = (String) i.next();

           String value = (String) map.get(key);

           text+=key + ” = ” + value;

       }

复制代码 代码如下:

<span style=”border-collapse: collapse; font-family: Arial, ‘Liberation Sans’, ‘DejaVu Sans’, sans-serif; line-height: 18px; font-size: 14px; white-space: normal;”><pre class=”lang-java prettyprint”><span>

</span></pre>

</span>

或者

or (Map.Entry<String,String> entry : map.entrySet()) {

  String key = entry.getKey();

  String value = entry.getValue();

  // do stuff

}   Iterator<Entry<String, String>> iterator = map.entrySet().iterator();

复制代码 代码如下:

        Entry< String, String> entry;

        while(iterator.hasNext()){

            entry = iterator.next();

            Log.d(“Key Value”,entry.getKey()+” “+entry.getValue());

        }
