    Default Getting user input and storing it into an array

    What I am trying to do is have the user get a prompt "Enter in a name: " when they enter in the name it is then added to an array list. After the name is added in the array list the user is then prompted again to enter in information this time the house number, then the street name, zip, country, state, balance.
    After that is all done an auto created account number will be assigned to that information.

    public void addAccount(int accountNumber,String name,String houseNum,String streetName,String city,String state,String zip,String country) {
    		Scanner reader = new Scanner(System.in);
    		System.out.println("Enter clients name: ");
    		clients[1].add(reader.nextLine());
    		System.out.println("Enter clients house number: ");
    		clients[2].add(reader.nextLine());
    		System.out.println("Enter clients street name: ");
    		clients[3].add(reader.nextLine());
    		System.out.println("Enter clients city: ");
    		clients[4].add(reader.nextLine());
    		System.out.println("Enter clients state: ");
    		clients[5].add(reader.nextLine());
    		System.out.println("Enter clients zip: ");
    		clients[6].add(reader.nextLine());
    		System.out.println("Enter clients country: ");
    		clients[7].add(reader.nextLine());
    		System.out.println("Enter clients initial account balance: ");
    		clients[8].add(reader.nextLine());
    		reader.close();
     
    	}

    How to go about getting the user input in that order into an array? I thought the way I was going about it was going to work however it didn't. I declared an array list at the top of my program so I can use it anywhere instead of just declaring it inside the method.
    Thank you for responding.

    How to go about getting the user input in that order into an array?
    Use an asssignment statement to put data into an array:
      theArray[theIndex] = theData;   // put data into the array
    Increment the index to move to the next slot in the array:
      theIndex++;  // move to next slot in the array

    it didn't.
    Please explain what happened and what you want to happen.

    I declared an array list
    An ArrayList is not the same as an array.
    The ArrayList uses methods to access its contents:
       theArrayList.add(theValue);  // add a value to the list
    An array uses array notation: [] with an index to access its contents
       theArray[theIndex] =  theValue;  // change value of array at theIndex
    If you don't understand my answer, don't ignore it, ask a question.

    Regardless of the warnings you might get, don't do this.

    reader.close();

    This is because you will closing System.in and would never be able to take any input from the console again.

    An array uses array notation: [] with an index to access its contents

    I wanted question to pop up using a simple print statment. Receiveing what the user wrote and storing it into clients.
    for example:
    Enter the clients name:
    user inputs: John
    clients index spot [1] now has john
    enter clients house number:
    user inputs: 455
    clients index spot[2] now has 455
    This would take in all the information needed to create a new bank account for a client and could be done an infinite amount of times adding new clients.

    The way I had it originally would give me an error based on .add(reader.nextLine()); the error was the method add(string was undefined for type string.

    an error based on .add(reader.nextLine()); the error was the method add(string was undefined for type string.
    You left off the variable that would have been before the .add
    For example: someObject.add(...
    What class object was the code calling the add method?

    Please copy the exact text of the error message as it was written by the compiler. Don't try to post a message from memory.
    What you posted is confusing.
    If you don't understand my answer, don't ignore it, ask a question.

    The way I had it originally would give me an error based on clients[1].add(reader.nextLine()); the error was "The method add(String) was undefined for type String". the .add portion is what causes the error.

    "The method add(String) was undefined for type String".
    The compiler can not find an add method in the client object class that takes a String as an argument.
    What class is the client array?

    When copying and pasting error messages, please do not mix the message's text with your comments. It makes it hard to see and understand the error message if there is other text mixed in with it.

    Please copy full text of the compiler's error message and paste it here.
    The message should show the source with a ^ under the location of the error.
    Here is a sample from the javac compiler:
    TestSorts.java:138: cannot find symbol
    symbol  : variable var
    location: class TestSorts
             var = 2;
             ^

    Can you answer my question: what class is a clients object? What methods does that class have?
    The compiler does not see an add method for that class.

    I can see the code but you need to be able to read the code and find the answer to my question.
    If you don't understand my answer, don't ignore it, ask a question.

    Neither of my classes have an add method in them. I apologize but I dont understand your question of which class is my clients object. Are you asking me what class is my clientsList under? If so that would be my account class. My accountList is in my client class.

    Yes, I am not asking about your classes.
    I am asking what class the clients object is. For example from your code:
    	private String streetName;
    The above statement defines streetName as a String class object.

    And
      private ArrayList<Client>clientList;
    defines clientList as an ArrayList object. Its data type is ArrayList.

    What is clients?

    I see you have fixed the code.
    Does the program work now?
    If you don't understand my answer, don't ignore it, ask a question.

    clients is a String array.
    Once I do an int parse for account balance it should work
