Question

Write a program which will get the personal names from the user and store them in a list (created using ArrayList) called personalNames. If there is any other character besides “a-z” or “A-Z” in a record, those should be flagged as ill-defined data. Because of the stated reasons above, instead of trying to fix the error in personal names, we want to remove this ill-defined data from the original list and move it to another list called errorProneNames. In other words, error involving records should be saved in a separate array. At the end your solution should print out the personalNames and errorProneNames lists separately.
