3 Read one line from the data file

1. Add a declaration of a local variable to the end of your setup. The variable should be
called header and should be type String.
2. Initialise header to the value returned from your scanner (in) when you call its
nextLine function. The complete line of code looks like this:
1 header = in. nextLine ();
3. Add a println statement to print the value of header.
4. Run your program. In the console panel you should see the first line of the file which
is the header line and not part of the data.
