    public static void main(String[] args) {
        // TODO code application logic here
        int NoCus = 0;
        getCustomers(NoCus);
    }
 
  public static void getCustomers(int NoCus){
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter the number of customers");
      NoCus = sc.nextInt();
      System.out.println("Number of customers entered  = "+NoCus);
      getDetails(NoCus);
      }//end GetCustomers
 
  public static void getDetails(int NoCus){
      for(int proCus = 0; proCus !== NoCus; proCus++){
 
      }
  }
 
}//end main

Thank you koder632417 i just thought since "=" means assignment and "==" meant evaluating equality then "!==" would be not equal anyways thanks a million

There are textbooks and documents online that explain these language details that you can use as handy references rather than guessing.
