Thread: phone book code problems

THE CODE IS SUPPOSE TO PROMPT USER TO MAKE A SELECTION BY ENTERING X,Y,Z.
THEN IF X IS ENTERED- IT SEARCHES FOR NAME IN THE TEXTFILE phonebook.txt.
Y IS FOR EDITING THE NAMES AND Z FOR ADDING A DIFFERENT NAME

                if(holder.startsWith(parameter, 0)) {
                results.add(holder);
                count++;
                }

              System.out.println("ZITA RASHAIKWA!!");
              System.out.println();
            }
            for(String r : results){
                System.out.println(r);
            }
            System.out.println("");
    }
     else if (paramet!=Y){
 
        System.out.println("Enter name to edit");
        Scanner kbdin = new Scanner(System.in);
              Scanner editname = new Scanner(System.in);
        String filename ="phonenumber.txt";
    FileWriter targetFile = new  FileWriter(filename);
    PrintWriter writer = new PrintWriter(targetFile);
 
writer.println(editname);
 
 
 
     }
 
else if (paramet!=Z){
    System.out.println("Enter name to Add to contacts");
 
        Scanner kbdin = new Scanner(System.in);
               Scanner addname = new Scanner(System.in);
       BufferedWriter out = new BufferedWriter(new FileWriter("phonebook.txt"));
    out.write("addname");
    out.close();

}   }
 
         catch(IOException e) {}}
        // TODO code application logic here
    }

The compile output is:

run:
Enter X to Search for name
Enter Y to Edit name
Enter Z to Add name
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code

Java Result:

There are quite a few errors in your code!!

For a start, you have declared the Scanner kbdin multiple times. Why?
You can easily do this with just 1 Scanner.

Also, this is wrong:

paramet = in.readLine();

If this is meant for the Scanner, the method readLine is undefined. Try .nextLine();
