Don't go in details and whenever you need a string out of number just write:
your_nuber + ""

For example,
int i = 289;
String str = i + "" ;
Now your i value 289 is in String str. In drawString method
g.drawString ( i + "", your_other_parameters ) ;
Now drawString will draw the value 289.

I am just giving you examples of converting a number to string and any details on any methods or anything else...
To be a purist, you can use String.valueOf ( i ) to get the string out of i.

Thanks
Kishori

Hi!
Can anyone tell me how to create a function which returns an initial string in reverse. I think you have to use another string where the characters of the initial string are appended backwards.

E.g Initial string = "Hello"
Returned string = "olleH"

Thanks
NM

hi,
Create a StringBuffer object from your string then call the reverse() method on it. This simply reverses the contents of it.

Simple when you know how.

OK thanx.
I got it working...but how do I get it into a function so that it returns the reversed string. I've only been doing Java for 3 days so any examples of code would be great.

Thanx. NM
