使用google-gson类库解析json文件
使用JsonParser解析器来解析字符串和输入流，变成json对象
代码如下：
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(); ???} ?}}使用google-gson类库解析json文件
