What's the answer for Challenge 4 of 4 for Java Basics?

The string for Which band looks like the others, but it's not correct.

Hi Andrew,

band hasn't been declared with a data type.

The challenge gives you the hint that it seems to be missing something at the start.

Here's the entire code I used:

String firstName = "Gordon";

String lastName = "Sumner";

console.printf("Hello %s", firstName);

String band = console.readLine("Which band?  ");

Can you post the entire code you have that you're trying to pass task 4 with?

Thanks Craig!

I'm enjoying the course a lot, by the way.

Hi Jason, thanks for replying...

Yeah! I thought defining it as a String was all it wanted:

String band = console.readLine("Which band? ");

Do I need another line of code?

No that should be it. Try refreshing the challenge. It's rare but sometimes they don't pass with correct code.

This is what passed for me: String band = console.readLine("Which band? ");

I don't see any difference.

I ran through it half a dozen times, and tried it in a new browser... it still didn't work. Let me know if you have other suggestions.

I sent a screenshot over to: help@teamtreehouse.com.

Thanks~

Hi Andrew!

I just ran through it and added the String declaration to the line in Task 4 of 4. It worked for me, I'll take a look at your screenshot, sorry for the frustration. I'll get to the bottom of it.

I see your screenshot! You broke my mock code I use for testing ;)

You added console.readLine to the first and second lines and it didn't need it, those should just remain as the strings you had.

I will update my mock to allow for that, and sorry for the frustration.

Let me know if you have any more problems.
