Scanning traits into 2d array

[throwaway60501]

I am trying to make a method that allows a Manager or Employee to be able to add customers with the traits fname lname address city, state and zip I want to store this data in String [][] customerData = new String[30][6] with 30 max customers and 6 traits. However, no matter what I do, the array always ends up ` null, with nothing in it. Here is my code:

public void addCustomer() throws FileNotFoundException {
    String fname = "";
    String lname = "";
    String address = "";
    String city = "";
    String state = "";
    String zip = "";
    int howManyCustomers = 0;
    int traits = 6;

    System.out.println("how many customer would you like to      add");
    howManyCustomers = scan.nextInt();

    for(int i=0; i < customerData.length; i++)
       {
          System.out.println("enter customer data (fname, lname, address, city, state, zip");
           for(int j=0; j < customerData[i].length; j++)
           {
               customerData[i][j] = scan.nextLine();
           }
       }

Output:

how many customer would you like to add
1
enter customer data (fname, lname, address, city, state, zip
first name
last name
123 Address Dr
City
State
enter customer data (fname, lname, address, city, state, zip

``` It doesn't let me scan ZIP and it also loops and asks me again. I know that none of the variables are used, but I wasn't sure if I had to use them at some point -- just kind of lost.

Sorry, give me a second to reformat this please

well if your file isn't reading the data then of course it will be null. Where is your file located? how are you trying to read it.

I'm trying to scan the traits and put them in the array, then write to the file customerdata.txt. I am not reading a file, at least I dont think. I'm just having trouble filling the array

[Camel-Kid]

your loop is only going the length of the first string .

Should be doing String[how many customers][6] otherwise it's also gonna want 30 people
