如何在Java中将JSON解析为Gson树模型？

public JsonObject getAsJsonObject() public JsonArray getAsJsonArray()

示例

import java.util.List; import com.google.gson.*; public class JsonTreeModelTest { public static void main(String args[]){ String jsonStr = "{"name":"Adithya","age":20,"year of passout":2005,"subjects": ["MATHEMATICS","PHYSICS","CHEMISTRY"]}"; JsonParser jsonParser = new JsonParser(); JsonElement jsonElement = jsonParser.parse(jsonStr); if(jsonElement.isJsonObject()) { JsonObject studentObj = jsonElement.getAsJsonObject(); System.out.println("Student Info:"); System.out.println("Name is: " + studentObj.get("name")); System.out.println("Age is: " + studentObj.get("age")); System.out.println("Year of Passout: " + studentObj.get("year of passout")); JsonArray jsonArray = studentObj.getAsJsonArray("subjects"); System.out.println("Subjects:" + jsonArray); } } } // Student class class Student { private String name; private int age; private int passoutYear; private List subjects; public Student(String name, int age, int passoutYear, List subjects) { this.name = name; this.age = age; this.passoutYear = passoutYear; this.subjects = subjects; } @Override public String toString() { return "Student{" + "name='" + name + ''' + ", age='" + age + ''' + ", year of passout=" + passoutYear + ", subjects=" + subjects + '}'; } }登录后复制
