Are you sure you want to reassign the standard input stream? I'll answer this for you: you really don't want to do this.

what do you mean?

System.in is now pointing to a text file that apparently only has one line. To read from both the file and the console use "new Scanner(new File("D:/Java/test.txt"))" as well as "new Scanner(System.in)". This will give you two Scanner objects. You currently don't; filePass and inputPass are not Scanner objects but Strings, and keyboard is your only Scanner object.

You're welcome.
