Not in its present state it can't. The formatting is really bad. Please format the whole thing correctly and post it again.

Hi
Please go through the same code removing the two lines of code shown here below and
write the command to compile and execute the same compiled  code to get the out put as under


  // System.out.println ("Project proj:" + proj.getProject());  (this is to show it has a link with Ant api especially on execution)
      //System.out.println ("Target targ:" + targ.getTarget());  (this is to show it has a link with Ant api especially on execution)
    
ie)

<target name="dist" depends="compile" />
</target>
**********************
As you see the build file so created contains only two lines of out put indicatiing a lot more to be java coded to get full build.xml
Also I mentioned (under the coded note)that this is not a classicalpattern of any type,but it is very raw And not formattedhully  to any  in its state and  meant
for amateured developers only.
They are not to be treated as a regular pattern wih its format.
Thanks

No, thank you. It is your job to supply decent code, not mine.

So you are happy to write illegible code?

Your program really needs to be formatted correctly, I agree with Campbell here.  Besides that, you have a method that looks like a constructor, and you are comparing variables to themselves.

Hi
This is  the  final modihied prg for your perusal with thanks

Building a buildfile for ant  via java prg programatically using ant api
is rather rare and ant is not to be treated as a programming language
So formating the code was not main crieteria since execution and out put
were given priority while coding

Hi
In order to be a a result oriented lines of code as below
I have used File class
Also used less space
