import java.io.*;
public class OutOut
public static void main(String args[]) throws IOException
PrintStream pr = new PrintStream(new FileOutputStream("outfile"));
System.out = pr;
System.out.println("Lets see what I see now??");
1. The code causes a compiler error. out is a declared final in
System and cannot be assigned to pr.
2. The code causes a runtime Exception due the assignment to a
final variable.
3. The code compiles and runs success fully. A file
called "outfile" is created and "Lets see what I see now??"
is printed in the same.
the Given ans:1
in my option :2
I can distinct the diference from ans1 and ans2.Somebody kind enough to clearfy me?
Author and all-around good cowpoke

The compiler can determine which variables are final, that is not a runtime function.
