lets say i have an array of String[] with this on it
HOw can i format its contents so that i get rid of the .txt on each component. Do i need to save them to a file, then read the file (get the line up the the dot) and then store it back the array or is there a simpler way!Code:String[] file = new String[3];
file [0] = "abc.txt";
file [1]= "def.txt";
file [2] = "ghi.txt";

Also is abc.txt a String? If so, should you enclose it in quotes?
It appears that you are posting uncompilable code, and this will serve no purpose other than to confuse. You may wish to re-state your question.
The array is of type String...
Read the API documentation for the String class and pay special attention to the indexOf( ... ) method(s) and the substring( ... ) method(s).Quote:

any can just post an example of just 1, so i can understand it!
No, it's so simple you can do it yourself: use the indexOf( ... ) method to find the start of the ".txt" String. Use the substring( ... ) method to chop that part of the String off. It's much more 'fun' to do it yourself instead of bluntly copying and pasting what I have written. I know how to do it, I knew that years ago already, no matter the programming language; it's your turn now.Quote:

Agree with Jos. You're always far better off to go to the API and try on your own first. Then if it still doesn't work after several attempts, come on back with your code. Otherwise you will appear to be asking for spoon feeding which will teach you nothing in the long run.Quote:

I was thinking more about the replaceAll(...) method myself.Quote:
