以下は私のコードです。小学校という名前の学校のみをフィルタリングしたいのですが、私のコードはそれをフィルタリングしません id この行if (object.getString("title") =="Elementary Schools")を削除すると、すべての学校が表示され、どのようにフィルタリングするのですか?

JSONObject json2 = new JSONObject(jsonresult);
status = json2.getString("status");
if (status.equals("1")) {
    message = "data";
    JSONArray school = json2.getJSONArray("data");
    for (int i = 0; i < school.length(); i++) {         
        JSONObject object = school.getJSONObject(i);
        if (object.getString("title").equals("Elementary Schools")){
            Category_ID.add(Long.parseLong(object.getString("school_id")));
            Category_name.add(object.getString("name"));
        }
    }
}

JSON レスポンス:

JUst do 

String title = object.getString("title");
if(title.equals("Elementary Schools"))
{
// Do you stuff
}

you can also use
if (object.getString("title").equalsIgnoreCase("Elementary Schools")
{`enter code here
// do you stuff
}

// if ステートメントの後の (;) をメモしたところ、それを削除してコードをテストします。
