            for (int k = 0; k < school.length(); k++) {
                JSONObject jb = (JSONObject) school.getJSONObject(k);
                Category_ID.add((long) k);

                Vacation_Date.add(jb.getString("date"));

if(!Vacation_Date.contains(jb.getString("date")))
{
  Vacation_Date.add(jb.getString("date"));
     //Do your stuff here .
}

您可以查看：

for(int=0; i<Vacation_Date.size();i++){

if(Vacation_Date.get(i).equalsIgnoreCase(sampledate)){

  // do your stuff here
}

}
