使用google-gson类库解析json文件

public class Readjson {

  public static void main(String[] args) {
    try {
      
      
      JsonParser parser=new JsonParser();
      JsonObject object=(JsonObject) parser.parse(new FileReader("test.json"));
      System.out.println(object.get("cat").getAsString());
      System.out.println(object.get("pop").getAsBoolean());
      
      JsonArray languages=object.get("language").getAsJsonArray();
      for(int i=0;i<languages.size();i++){
        System.out.println("*************");
        JsonObject lan=languages.get(i).getAsJsonObject();
        System.out.println("id="+lan.get("id").getAsInt());
        System.out.println("name="+lan.get("name").getAsString());
        System.out.println("ide="+lan.get("ide").getAsString());
      }
      
    } catch (JsonIOException e) {
      e.printStackTrace();
    } catch (JsonSyntaxException e) {
      e.printStackTrace();
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    }

  }
