How to reset standard input and output in java?

I have following java code which redirects standard input and output to files:

FileInputStream fin=new FileInputStream("In.txt");
System.setIn(fin); //Standard input will be taken from file In.txt

FileOutputStream fout=new FileOutputStream("Out.txt");
PrintStream p=new PrintStream(fout);
System.setOut(p); //Standard output of the program will be written to file Out.txt

Now after performing necessory operations I want to reset the IO. i.e. the program should again accept input from keyboard and print output on the screen. Is there any code for that? Please help

What about this

InputStream in = System.in;
System.setIn(something else);
// do something

System.setIn(in);

Messing about with System.in and System.out is a serious hack which is unlikely to work quite the way you want. You are better of finding another way to read one file and write to another.
