Thread: 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.

Please explain what happened and what you want to happen.


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

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.

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.

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.

This is all of my code as it is right now.

I can see the code but you need to be able to read the code and find the answer to my 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.

Slowly but surely. Thank you for your patience.
