1.map 的遍历
public voidtraversingMap(Map<String,String> map){
//方法一：通过Entry遍历<迭代Entry>
for(Entry<String, String> entry : map.entrySet()) {
System.out.println(entry.getKey()+"："+entry.getValue());
}
//方法二：通过Set集合遍历<迭代Set>
for(String key: map.keySet()){
System.out.println(key + "：" +map.get(key));
}
}
1.map的知识
/*第一种方法
