2.   Map<string, string> map=new hashmap<string, string> ();      Map.put ("name", "Lao Wei");      Map.put ("Sex", "male");      Map.put ("Address", "Dalian");  

   
   

4. Method 1

6. For (map.entry<string, string> MapString:map.entrySet ()) {   String key=mapstring.getkey ();//Times method Gets the name of the key-value pair   String Value=mapstring.getvalue ();//Secondary method gets the value   of a key-value pair System.out.println (key+ ":" +value);

10. Method 2   

12.       for (Iterator Iterator = Set.iterator (); Iterator.hasnext ();) {            Map.entry string = (map.entry) iterator.next ();            String key= ((entry<string, string>) string). GetKey ();//Times method Gets the name of the key-value pair            String value= ((entry<string, string >). GetValue ();//Times method Gets the value of a key-value pair            

    
    

14. Method 3

    Map map = new HashMap (), Map.put ("Dog", "dogs"), Map.put ("Cat", "cat"), Map.put ("Monkey", "monkey"); for (Object Se:map.keySet ()) { string s = (string) map.get (SE); System.out.println (s);}
