Comment puis-je analyser une réponse JSON enregistrée dans un fichier texte

Question

Je cherche un tutoriel sur la réponse JSON à l'aide de Java.Le tutoriel http://www.javabeat.NET / 2012/04 / Parsing-JSON-UTIL-Java-and-gson-bibliothèque / qui dit:

lire le document JSON à l'aide de JSONReader, en supposant que le document soit présent dans les systèmes de fichiers:

JsonReader reader = new JsonReader(
        new InputStreamReader(new FileInputStream(this.jsonSource)));

Je ne comprends pas pourquoi nous utilisons cela et qu'est-ce que cela signifie par JSonsource.Ma réponse JSON est enregistrée dans un fichier texte.Comment puis-je y faire face?Devrais-je mettre le chemin du fichier texte ou quoi?Quelqu'un peut-il préciser à moi comment analyser une réponse JSON, en particulier, Yahoo Boss, afin d'extraire les liens des résultats de la recherche.Pour l'instant, j'ai pu enregistrer la réponse dans un fichier texte.C'est comme (cette réponse pour le mot clé Yahoo):
