使用Java创建Json文件

package testCreateJson;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import com.google.gson.JsonArray;

import com.google.gson.JsonObject;

/**

public class CreateJson {

public static void main(String[] args) throws Exception {
JsonObject object = new JsonObject(); //创建Json格式的数据
object.addProperty("category", "IT");
object.addProperty("pop", true);

JsonArray array = new JsonArray();

JsonObject subJsonObj1 = new JsonObject();
subJsonObj1.addProperty("id", 1);
subJsonObj1.addProperty("ide", "Eclipse");
subJsonObj1.addProperty("name", "Java");
array.add(subJsonObj1);

JsonObject subJsonObj2 = new JsonObject();
subJsonObj2.addProperty("id", 2);
subJsonObj2.addProperty("ide", "XCode");
subJsonObj2.addProperty("name", "Swift");
array.add(subJsonObj2);

object.add("languages", array);

System.out.println(object.toString());

FileWriter fw = new FileWriter(new File("create.json"));
