Android : Android JSON parsing same attribute

I have a JSON response like this :

images: [

{

small: "/productimages/247DRFS100374LAV/small/247DRFS100374LAV_1.jpg",

medium: "/productimages/247DRFS100374LAV/medium/247DRFS100374LAV_1.jpg",

large: "/productimages/247DRFS100374LAV/large/247DRFS100374LAV_1.jpg"

},

{

small: "/productimages/247DRFS100374LAV/small/247DRFS100374LAV_2.jpg",

medium: "/productimages/247DRFS100374LAV/medium/247DRFS100374LAV_2.jpg",

large: "/productimages/247DRFS100374LAV/large/247DRFS100374LAV_2.jpg"

}

],

Since, the Image attribute gives 2 objects with exact same attributes (Small, medium and large), I want to extract only large images from both objects. How can I do this ? please help, I'm a beginner.
