how to match value of string in arraylist

Question

How to match string with ArrayList and check if is found or is not found I'm getting list of dates from json and save in ArrayList. How will I match ArrayList with string to check ArrayList contains string value or not?

string sampledate; sampledate="26/5/2013";

    static ArrayList<String> Vacation_Date = new ArrayList<String>();



            JSONObject json3 = new JSONObject(str2);

        status = json3.getString("status");
        if (status.equals("1")) {

            JSONArray school = json3.getJSONArray("data");

            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.equals(sampledate)
  {
      //dosomething   
         }





         idid like this  
            if(Vacation_Date.equals(mydate))

        //in debug mode vocation is this    [2013-09-29, 2013-09-25, 2013-10-05, 2013-09-27]

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

@smartguy yes you can use arraylist.contain("valuetoCheck") for checking if arraylist contains that value or not, Please explain if im am wrong .

You can check by this:

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

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

  // do your stuff here
}

}

first you have to get your string from array list and then convert it to simple date format and after that compare the string with your date string
