CMIS 141 Methods Modify the Roman.java program so that the switch statement is replaced by a call to a method that has a char argument representing a Roman "digit" and returns the int value of that Roman "digit". The statement with the call should look something like: sum += romanValue( c ); The method will mostly consist of a switch statement. Modify the Rectangles.java program so that making the box is done in a method. The arguments to the method are a JTextArea to append text into, an int that is the number of rows, an int that is the number of columns. The method retuns nothing, i.e. it is a void method. It basically consists of the nested for loops. Add another method that makes a filled-in rectangle. Test that it works. Present to the user a choice menu of whether to make a rectangle or a box.
