Exercises

1. Modify the FormattedWriter class to support centered output of the value in the output field.

2. Use a StreamTokenizer object to parse a string entered from the keyboard containing a series of data items separated by commas and output each of the items on a separate line.

3. Create a class defining an object that will parse each line of input from the keyboard that contains items separated by an arbitrary delimiter (for example, a colon, or a comma, or a forward slash, etc.) and return the items as an array of type String[]. For example, the input might be:
   
   1/one/2/two
   
   The output would be returned as an array of type String[] containing "1", "one", "2", "two".
