Redirect standard output

[Cylab]

Assumming that program name is "XML.java",
perform the followings for each input file:

java Xml < input1.txt
java Xml < input2.txt
:
Code:
class XML{
................main(String[] args){
BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));

String fileName = bf.readLine();
File file = new File(fileName);
FileReader fr = new FileReader(file);
StreamTokenizer st = new StreamTokenizer(fr);
:
processing
:
}
}

Question: but I can not redirect to file by >. How can I do?

Mind adding a few lines please???????????

I'm sorry for sounding silly but I don't see any IO redirection in your code; note that there are the methods System.setOut( ... ) and System.setIn( ... )

kind regards,

No more hints from me (because I don't know of any) but if I had to do it I would create two simple methods:

private void setIn(String name) { ... }
private void setOut(String name) { ...
 }

... that redirect the input resp. the output stream to a FileStream given the name of the file. Then, given a method that reads from System.in and writes to System.out, I'd be able to do:

setOut("myOutFile.txt");
setIn("myInFile1.txt"); method();
setIn("myInFile2.txt"); method();
setIn("myInFile3.txt"); method();
System.out.close();

kind regards,

Jos
