I've been trying to code a program that takes in user input to input it into an arraylist. I'm not sure what is going on here or why there are errors.

The size of itemNames is 0.

rainymc_OP•3mo ago

the value "i" is set to 0

rainymc_OP•3mo ago

this is the error code

szatkus•3mo ago

Which is caused by?

rainymc_OP•3mo ago

according to it on line 13 which is "itemNames.add(inpt.next());" the scanner method is undefined but I've defined my scanner object

szatkus•3mo ago

Which is totally correct code.

rainymc_OP•3mo ago

So what's the problem here?

szatkus•3mo ago

I don't know, the code on the screenshot wouldn't throw any compilation error, although it's noop.

You probably should add something to itemPrices?

rainymc_OP•3mo ago

Yes that’s for afterwards but as of right now I’m only trying to find a solution to my itemNames issue

Tomasm21•3mo ago

When I entered all your code there are no issues. I don't have such an exception. But I edited your code so it would work and let you enter items and prices.

rainymc_OP•3mo ago

Well I’m trying to have it so the user will input an answer and the answer will be placed into an array list which I will print later I’m not sure if inpt.next is the right statement for such a thing

szatkus•3mo ago

Then you have to think throught your stop condition.

rainymc_OP•3mo ago

I have it so if the user says stop the loop will break

Please format your code to make it more readable. For java, it should look like this:

```java
public void foo() {
 
}
```

```java
public void foo() {
 
}
```

rainymc_OP•3mo ago

Alright I’ll try it in a bit
