You can try it with switch(). You can split the day into "DayOfTheWeek" (I think).

EDIT: YOU CAN USE ArrayList to combine this day together. Declare it globally;

List<JSONObject> dayone=new ArrayList<>();
List<JSONObject> daytwo=new ArrayList<>();
List<JSONObject> daythree=new ArrayList<>();
....

And in code

    JSONArray jarr=new JSONArray(responseString);
    for(int i=0;i<jarr.length;i++){
     JSONObject obj=jarr.getJSONObject(i);
    String day=obj.getString("DayOfTheWeek");
    switch(day){
     case "1":  //for sunday
     String classId=obj.getString(ClassRoom_ID);
     dayone.add(obj);   //object ob day one
    //...... parse data//
     break;
     case "2":  //for monday
//...... do your code//
    daytwo.add(obj);   //object ob day two
     break;
    case "3":
//...... do your code//
     break;
    case "4":
//...... do your code//
     break;
    case "5":
     break;
    case "6":
     break;
    case "7":
     break;
 }
}
for(JSONObject jobj: dayone){
    String classId=jobj.getString(ClassRoom_ID); //class id of dayone
}

TreeMap<String, List<JSONObject>>?

.

Map<String, List<JSONObject>> map = new TreeMap<>();

JSONArray jarr=new JSONArray(responseString);
for(int i = 0; i < jarr.length; i++) {
    JSONObject obj = jarr.getJSONObject(i);
    String day = obj.getString("DayOfTheWeek");

    // Get the list
    List<JSONObject> jsonList;
    if (map.containsKey(day)) {
       jsonList = map.get(day);
    } else {
        jsonList = new ArrayList<JSONObject>();
    }

    // Add to the list
    JSONObject obj = new JSONObject(); // for example
    // obj.put(key, value);            // for example 

    jsonList.add(obj);

    // Update the list
    map.put(key, jsonList);

}
Log.d("grouped values", map.toString());
