Hello I am new to java and learning it.
I want to delvelop one application which will take one text file as
input and will show the certain parts of the text file based on the
condtion. I want to replace the particular part in the text file with
some other part on different conditions.
Can I do lot of text processing in java?
if yes which part of the java should I read ?
Please help.

Yes it is, a better question might be: is Java too powerful?

Unless doing this as a learning exercise, I'd use sed, awk or Perl.

You can do text processing in assembler, Fortran or Ook. Perhaps what
you mean is: does the Java language (specifically the J2SE platform)
include specific features which are oriented towards text-processing tasks.

Java has methods and classes for reading and writing text files in many
common encodings (e.g. UTF-8), for processing input streams a line at a
time and for applying regular expressions for selecting and replacing text.

Sun's Java tutorials at their website. (Google for "Java tutorial").

Yes.

Probably regular expressions and IO. If you want to make add a GUI,
you'll also want to read about Swing.

I would consider Java a good choice (maybe not the best
but good).

You just need basic Java stuff: the language plus java.lang, java.io
and maybe java.util classes.
