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 – Essaylink

1. 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.)

2. 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).
