Using a text editor or wordprocessor, create a text file holding a series of surnames and payroll numbers (at least five of each). For example:

Smith 123456 Jones 987654 Jenkins 555555

... ...

Now write a Java program that uses a while loop to read values from the above text file and displays then in a table under the headings 'Surname' and 'Payroll No.'. (Don't be too concerned about precise alignment of the columns.)

then Take a copy of the above program, rename the class and modify the appropriate line so that the program accepts input from the standard input stream (i.e., using a Scanner around the standard input stream, System.in). Then use redirection to feed the values from your payroll text file into your program (displaying the contents as before).
