I'm building an Android app for displaying school timetable, with the JSON data coming from a URL. However the JSON is formatted in a way that the needed arrays are inside a named "lessons" object. How would it be possible to get access to the arrays I need?

This is how my JSON looks

{
    "week": "2019-04-01",
    "times": {
        "1": "07:00-08:29",
        "2": "08:30-10:00",
        "3": "10:15-11:45",
        "4": "11:55-14:00",
        "5": "14:10-15:40",
        "6": "15:45-17:15",
        "7": "17:20-18:50",
        "8": "18:55-20:25",
        "9": "20:35-22:05",
        "lunch": "12:40-13:15"
    },
    "lessons": {
        "2019-04-01": [{
                "lesson": "2",
                "start": "08:30",
                "end": "10:00",
                "subject": "PHP",
                "group": "IS117",
                "teacher": "Jane Doe",
                "room": "A-222"
            }
        ]
    },
