Thread: Why my Java Project don't work?

Hello to everybody, First, I present myself: I am a french, I live in Paris and right now I am doing a training in Java programming language here in Paris to become a Java developer.My first language speaking is french but I prefer studying Java in English because it's more complete and I like English language.
Well I have a project in Java: Managing a bank account.It's written(the comments) in french but I try to translate in English.
The IDE used is Eclipse.
The fist java file is:

import java.util.*;
public class Projet {
 public static void main (String [] args) {
  byte choix;
  char typeCpte ='\0';
  double val_courante = 0.0, rate = 0.0;
  long numéroCpte = 0, numéroLu = 0 ;
  Scanner Clavier = new Scanner(System.in);
  System.out.println("                               WELCOME TO THE BANK.");
  System.out.println("1. Create an account");
  System.out.println("2. Viewing an Account");
  System.out.println("3. Write an accounting line");
  System.out.println("4.Log out");
  System.out.println("5.Help");
  System.out.println();
  System.out.print("Your choise: ");
  choise = Clavier.nextByte();
  //Option 1
  System.out.print("Account type [Possible types : ");
  System.out.print("C(current), J(oint), E(savings)] :");
  typeCpte = Clavier.next().charAt(0);
  System.out.print("Account number :");
  numberCpte = Clavier.nextLong();
  System.out.print("First credited value  :");
  val_courante = Clavier.nextDouble();  //current value
  //If savings accout
  System.out.print("Placement rate :     ");
  rate = Clavier.nextDouble();
  //Option 2
  //asks the user to enter the account number to display
  System.out.print ( " Which account would you like to view ? : ");
  numberRead= Clavier.nextLong();
  //If the account number exists, 
  System.out.print("The account n° : " + numberCpte + " is an account ");
  // displays its rate in the case of a savings account.
  System.out.println("savings whose rate is " + taux);
  System.out.println("First credited value : " + val_courante);
  // Otherwise, it displays a message indicating that the account number is not valid.
  System.out.println("The system does not know the account " + numéroLu);
  //Option 3, the program displays "option not programmed"
  System.out.println("Option not programmed");
  //Option 4,  the program ends its execution
  System.out.println("Goodbye and see you soon");
  // System.exit(0) ;    
  // Option 5
  // the program displays an explanation line for each option
  // from the main menu.
  System.out.println("Option 1. To create a Current account enter C");
  System.out.println("          To create a Joint account enter J ");
  System.out.println("         To create a Savings account enter E");
  System.out.print("          Then, enter the account number, and"); 
  System.out.println(" its first credited value");
  System.out.println("          In the case of a savings account, enter the rate");
  System.out.println("Option 2. The system displays the data of the chosen account ");
  System.out.println("Option 3. Write an accounting line");
  System.out.println("Option 4. To exit the program");
  System.out.println("Option 5. To display help");
 }
}

The Account.java file is:

When I execute the Projet.java I obtain:

WELCOME TO THE BANK.
1. Create an account
2. Viewing an Account;
3. Write an accounting line
4.Log out
5.Help"
Your choice : when I enter 1 or 2 or 3 or 4 or 5 I obtain always the same message:
Votre choix : 2
Type of account [ possible Types : C(current), J(joint), E(Saving)] :
What is wrong with those programs.Thank you in advance for your help.

Fisrt, thank you for your answer.
When I type 2, I obtain the same message as when I type 1:
Type of account [ possible Types : C(current), J(joint), E(Saving)] :
