例一。(org.json包)
首先导入org.json下面的包
package com.sun;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class Test {
public static void main(String args[]) throws JSONException {
String jsonContent = "{'hello':world,'abc':'xyz'}";
JSONObject jsonObject = new JSONObject(jsonContent);
String str1 = jsonObject.getString("hello");
String str2 = jsonObject.getString("abc");
System.out.println(str1);
System.out.println(str2);
System.out.println("------------------");
jsonContent = "[{'hello':333,'abc':'false','xyz':{'a':1,'b':'ab'}},{'hello':555,'abc':'true','xyz':{'a':2,'b':'ba'}}]";
JSONArray jsonArray = new JSONArray(jsonContent);
for(int i=0;i<jsonArray.length();i++){
JSONObject jsonobject2=jsonArray.getJSONObject(i);
int value1=jsonobject2.getInt("hello");
boolean value2=jsonobject2.getBoolean("abc");
// String value3=jsonobject2.getString("xyz");
JSONObject jsonobject3=jsonobject2.getJSONObject("xyz");
int value4=jsonobject3.getInt("a");
String value5=jsonobject3.getString("b");
System.out.println(value1);
System.out.println(value2);
System.out.println(value4);
System.out.println(value5);
}
}
}
输出结果
world
xyz
------------------
333
false
1
ab
555
true
2
ba
