第一种方法根据键值的名字取值

import java.util.HashMap;
import java.util.Map;

public class Test {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
        Map<String, Object> map=new HashMap<String, Object>();
        map.put(“id”, “sunny”);
        map.put(“value”, “syl”);
        
        System.out.println(map.get(“id”));

        System.out.println(map.get(“value”));
 }

}

第二种方法 遍历

import java.util.HashMap;
import java.util.Map;
import java.util.Set;

public class Test {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
        Map<String, Object> map=new HashMap<String, Object>();
        map.put(“id”, “sunny”);
        map.put(“value”, “syl”);
        
        Set<String> get = map.keySet(); 
        for (String test:get) {
         System.out.println(test+”,”+map.get(test));
        }
 }

}
