Try this:

for (int i=0; i<n; i++){
    int itis = sc.nextInt() - 1;
    if(allData[itis] != null){
        allData[itis].add(i);
        if (allData[itis].size() == k) {
            for(int j=0; j<k; j++){
                result[j].addFirst(allData[itis].poll());
            }   
        }
    }
    
}
