1. Implement class comparator wich will compare records according your sort preferencies,
like this:
     public class record_Comparator implements Comparator{
          public int compare(Object emp1, Object emp2){
      // here is your code for return -1if 'before'  or 0 if equal or 1if 'after'
               int stepId_1 = ((record)emp1).get_someValue();       
               int stepId_2 = ((record)emp2).get_someValue();
               if(stepId_1 > stepId_2)
                    return 1;
               else if(stepId_1 < stepId_2)
                    return -1;
               else
                    return 0;   
than call method sort() with your collection of records,
like this:
Collections.sort(record_collection, new record_Comparator());
