Whoops! My bad! I forgot all about the fact that Java doesn't allow unreachable statements. I knew that the "break" commands would never execute, but I got in the habit of sticking them in anyway. ...

I think a switch statement would be appropriate here:

Generally, toString() will not take any parameters. Use the object's data members (StudentName, qz1, qz2, qz3, qz4, qz5) and display them. I cannot think of any reason you'd want to make this a...

The spec doesn't say anything about making an "array list". It says to make an array.

One, the rule is that we don't help without effort on your part. Two, you should start your own thread.

nextInt (int) requires a positive parameter. You are passing it arr[0], which is 0, which is an error. From the documentation:

Yes, many here can solve it. But you need to show your attempt and ask a specific question. If you do, many people will be happy to help.

One, your class is named Main3, not Main1, so make sure your html file points to the actual class file. I renamed the class to Main1 and compiled it. When I did, it created Main1.class, but it also...

Code tags and formatting please. The code is unreadable now as it is.

Before you can work on the borrowing function, you need to set up your ArrayLists correctly.

One, code tags. Use them.

Two, Where's the error and what is it? Point out a line number.

Code tags are simply this.

First, if you haven't already, after you've read in your data, you need to display it to make sure it's reading in correctly. You also need to make sure that the number of elements you are reading...

You keep writing over the same data because you don't change Index. Index++ should be at the end of the loop. You have 59 lines in your file (I assume those blanks in your first post aren't blank...

Yes to all of the above. Java can do all of this, or at least it probably can since I don't know what GST is. I don't know that it's worth learning Java just to do that, but you could certainly...

I think my post 2 is your best approach then:

Yes, very good point. A single array or type Hurricane would be better than several arrays, each containing one part of the hurricane, like the name, date, etc. You should create a Hurricane class....

OK that's what it should do. Does it actually do that? You need to tell us. Again, if I type 25, what's the goal? Calculate all primes up to 25? Calculate the first 25 primes?

There are a lot of problems with both the algorithm and the program's implementation of the algorithm. Let's start with primes[]. What should primes[] eventually contain if I enter a max of 25? Is...
