请问怎样遍历TreeMap

---

entrySet?
里面的对象是Map.Entry

---

?我是想想遍历TreeMap

---

Iterator it = map.entrySet().iterator();
while(it.hasNext())
{
//里面写你想做的事情
}

---

TreeMap map = new TreeMap();
map.put(-#34;value_0-#34;, new Integer(0));
map.put(-#34;value_1-#34;, new Integer(1));
map.put(-#34;value_2-#34;, new Integer(2));
Iterator it=map.values().iterator();
while(it.hasNext()){
Integer val=(Integer)it.next();
System.out.println(val.toString());
}

---

我要同时得到KEY和VALUE的值

---

TreeMap map = new TreeMap();
map.put(-#34;value_0-#34;, new Integer(0));
map.put(-#34;value_1-#34;, new Integer(1));
map.put(-#34;value_2-#34;, new Integer(2));
Iterator it=map.keySet().iterator();
while(it.hasNext()){
String key=(String)it.next();
Integer val=(Integer)map.get(key);
System.out.println(key.toString());
System.out.println(val.toString());
}

---

。。。 。。。

---

Iterator its = treeMap.keySet().iterator();
int num=0;
while (its.hasNext()) {
Object objs = its.next();
clfs[num]=objs+-#34;(-#34;+list.get(objs).toString()+-#34;)-#34;;
num++;
// System.out.println(-#34;-------#62;-#34;+objs + -#34;: -#34; + list.get(objs));
}
