Wow. Thanks so much. I'm not 100% sure on why it didn't work the way I had it as I've written a couple simple programs before and they executed perfectly and were written just like this one. It didn't involve any if statements, but it accepted data input and was written the same. If you have the chance to explain more, ...

18. Listbox to string

I can't imagine why a tutorial should cover that. Seems like a weird idea to me. But all you have to do is to iterate over the entries in the list box and append each of them to the text area. I would go into detail if I thought you were asking about Swing and not (say) HTML.

19. Silly string problem

Hello Jezzica85, tabs do not replace 8 spaces but jumps to a position that is dividable by 8. So the strings a\t| aa\t| aaa\t| do all align although they have different length. So you should change your algorithm a bit: 1) add \t to jump to the next position that is dividable by 8 until you reach the position 96. (Be ...

there are some things i don't understand in your code: 1/ what is the 'i' variable used for?! 2/ for ( int iC = 0; iC > stringData[0].length; iC++ ) ---> why is the operator '>'? stringData[0].length will never be < to 0 3/ and why are you getting a sortedMap, in the first place, instead of a String[][] array?

60. Reference a Vriable by its Name as a String

I presume you're thinking about mapping, say, attributes into fields of the same name. You can certainly do this by reflection using the getField(String name) method of the Class object. It's generally more flexible though to use setters obtained by getMethod() (mapping attribute xxxx onto setXxx()). It can be a bit of a security risk, though, because there may be fields ...

you could store into the database both strings- one without the html and another with the html I totally disagree with this. Presentation HTML has no business in a database.

Actually String is a bit of a weird one. Essentially it's an Object class but it gets a lot of special handling.

Also, like a primitive, it ...

I think teachers used the Keyboard class before Scanner was introduced.

You could easily alter that implementation and concatenate with another array on the fly if necessary.

This is so trivial that it barely deserves the words "design" or "application". You can use java.util.Scanner to get user input from the command line.

Good ...
