Write name by stars in JAVA

[aRTx]

Write a Java program with a text field, a button, and a text area as shown in Figure 4.12. A user may enter a string in the text field. When the button "Print" is clicked, the text area will display the pattern of the string formed with the character '*'.

What have you done thus far? Do you have any ideas you've come up with to tackle this problem?

I would personally just brute force it and store each letter & number in its own String[]. All the letters will need to have the same number of spaces/stars, and you'll need to set the text box to Monospace. Then just concatenate each String[]'s same indexes together for one whole horizontal line of stars and spaces.

A text can be written to a buffered image or similar objects. You could use black text on a white background for this purpose and thereby obtain a model which merely need to be scaled so that each black pixel may be properly represented by an asterisk. This neatly deals with multiple fonts, styles, and even character sets.

Yes. This is the best way. Clean and simple.

+1 Please don't provide support for home work assignments. The OP isn't going to learn any thing by us just giving out our solutions.

Rather wait for him/her to come back and explain what they have done and maybe where they are stuck on.

@kavon89 : thanks a lot for the idea, seems like a fun problem so I decided to give it a shot (I m not the thread creator). String[][] would be the better choice
btw, seriously, what does OP stand for? :)

And drubin is correct - if this is homework the thread is likely to be closed.

Thank you very much for your ideas. I have learned a lof from your comments but finally I have found the source code and I want to share with you ;)

The funny thing about this OP is that he doesn't even make an attempt to disguise that this is homework -- it's just word by word copypaste, even with this "see figure (that does not exist in post)" stuff kept :D

Closing here, sorry, please see post #7 for the CoC quote. Thanks.
