Question

I have written a program to search if the particular item is present in the file or not.. so why is there any error hope it is right!
BufferedReader check;
     try{
         check=new BufferedReader(new FileReader(FileName));
    }catch(FileNotFoundException ex){
        System.out.println("Sorry file not found");
        return; 
                            System.out.println("Enter the item to be found");
                            String input_item=in.readLine();
                            String item= input_item.toUpperCase();
                            System.out.println("Searching for "+item);
                            int messenger=0, x=0;
                             while(x<sType.length) {
                                sType[x]=check.readLine();
                                sNum[x]=Integer.parseInt(check.readLine());
                                sPrice[x]=Float.parseFloat(check.readLine());
                                if(item.equals(sType[x])) {
                                    System.out.println("Found "+sType[x]);
                                    System.out.println("-------------------------------------------------------");
                                    System.out.print("Stock Name :");
                                    System.out.println("\t"+sType[x]);
                                    System.out.print("Stock Level:");
                                    System.out.println("\t"+sNum[x]);
                                    System.out.print("Stock Price:");   
                                    System.out.println("\t$"+sPrice[x]);
                                    System.out.println("-------------------------------------------------------");
                                    messenger=1;
                                x++;
                            if(messenger==0) {
                                System.out.println("Sorry "+item+" not available");
