          double first,second;
          boolean exit = true;
          double revenueback;
          double revenueBetween;
          double lowestRevenue;
          double highestRevenue;
          AnnualHireRevenue hirecom = new AnnualHireRevenue();
          while (exit)

          System.out.println("2 enter vehicle's revenue");
          System.out.println("3 get revenue of a given vehicle");
          System.out.println("4 enter two revenue and return the vehicles between that revenues");
          System.out.println("5 display the lowest revenue");
          System.out.println("6 display the highest revenue");
          System.out.println("7 display all revenue");
          System.out.println("8 Exit");
opt = EasyIn.getInt();     
                    switch (opt)
               case 1:hirecom.setNames();break;
               case 2:hirecom.getRevenue();break;
               case 3: System.out.println("Enter a vehicle number which you want the revenue of");
                              sale = EasyIn.getInt();
                              revenueback=hirecom.getSales(sale);
                              System.out.println("This is the revenue �" +      revenueback);break;
               case 4: System.out.println("enter first revenue");
                         first = EasyIn.getDouble();          
                         System.out.println("enter second revenue");
                    second = EasyIn.getDouble();
                         hirecom.getNoOfVehicles(first,second);
                         revenueBetween = first-second;
                         System.out.println("the revenue between that two revenues you given is �" + revenueBetween);break;
               case 5:lowestRevenue=hirecom.displayLowest();
               System.out.println("The lowest revenue is �" +lowestRevenue);break; 
               case 6:highestRevenue=hirecom.displayHighest();
               System.out.println("The highest revenue is �" +highestRevenue);break;

               hirecom.displayAllRevenues();break;
               case 8:{
               char reply;
               System.out.println("Are you sure you want to exit? Y to exit and N to continue");
                         if(reply = Y)
                         exit = false;
                         else
                              exit = true;
                              }break;

Assuming that you can extend / improve class EasyIn to add a getChar() method in addition to your getDouble and getInt(), you should be all set. Something like this:
  System.out.println("Are you sure you want to exit? Y to exit and N to continue");
  try {
    System.out.flush();
    BufferedReader br = new BufferedReader(new InputStreamReader( System.in ));
    char[] chars = new StringTokenizer(br.readLine()).nextToken().toCharArray();
    reply = chars[0];
  catch (IOException ioe) {
    System.out.println(ioe);
