Array permitting duplicate record

Question

Hi,
I have string array like below:
String strArr[] = {"style1","style2","style2","style4"};
In this string array index 1 and index 2 is having same value which is style2.
My target is to generate key(system time) for each value as below:
"key1" : "style1"
"key2" : "style2"
"key2" : "style2" //Here I want to reuse already generated key2 in place of creating new key like key3
"key4" : "style4 "
At last generated array should be:
["key1" : "style1",
"key2" : "style2",
"key2" : "style2" , //Here I want to retain this duplicate record
"key4" : "style4 "]
Value position is also important, like below array is not accepted:
["key2" : "style2",
"key1" : "style1",
"key2" : "style2" ,
"key4" : "style4 "]
I am struggling to achieve this.
Please guide me to achieve this!
Regards
My Efforts:
     static Map<String, String> m = new HashMap<String, String>();
     static int[] intarr;
     static List<Integer> list = new ArrayList<Integer>();
     public static void main(String[] args) throws InterruptedException {
          String strArr[] = {"style1","style2","style2","style4"};
          /**Find Index having duplicate value*/
          for(int i=0; i<strArr.length; i++){
               for(int j=0; j<strArr.length; j++){
                    if((strArr==strArr[j])&&(i!=j)){
                         list.add(i);
                         String newclass = "class"+new Date().getTime();//
                         //Thread.sleep(1000);//
                         m.put(newclass, strArr[i]);//
                         break;
          for(int i : list){
               //System.out.println("Duplicate value found at Index:: "+i);
          /*String newduplicateclass = "class"+new Date().getTime();
          Thread.sleep(1000);
          for(int i=0; i<strArr.length; i++){
               if(list.contains(i)){
                    System.out.println("i="+i);
                    m.put(newduplicateclass, strArr[i]);
               }else{
                    String newclass = "class"+new Date().getTime();
                    m.put(newclass, strArr[i]);
                    Thread.sleep(1000);
          System.out.println(m);
But want to do with smartest way using few lines of code.

Answer 1

@TPD Thanks for your help! It gave me a speed up.
At last I am done with what I wanted and below is that code:
public static void main(String[] args){
          String strArr[] = {"style7","style1","style5","style7","style2","style1","style2","style7","style2","style5","style7","style7"};
Set<String> set = new HashSet<String>();
          for(int i=0; i<strArr.length; i++){
               set.add(strArr);
          Object objArr[] = set.toArray();
          int counter = 0;
          Map<String, Integer> map = new HashMap<String, Integer>();
          for(int j=0; j<objArr.length; j++){
               map.put(objArr[j].toString(), counter);
               counter++;
          JSONArray jsonArr = new JSONArray();
          JSONObject jsonObj;
          for(int i=0; i<strArr.length; i++){
               jsonObj = new JSONObject();
               jsonObj.put(strArr[i], map.get(strArr[i]));
               jsonArr.add(jsonObj);
          System.out.println(jsonArr);
//OUTPUT: [{"style7":0},{"style1":2},{"style5":1},{"style7":0},{"style2":3},{"style1":2},{"style2":3},{"style7":0},{"style2":3},{"style5":1},{"style7":0},{"style7":0}]
