Regular Expressions
Terms and concepts that will be covered in OOPDA
Regular expressions are very powerful ways to validate patterns of strings, e.g. phone numbers, email addresses, social security numbers, product numbers and so on. Here's a good tutorial on the classes needed to implement regular expressions. Here's a link to some popular regular expressions that describe each example.
An enum type is a special data type that enables for a variable to be a set of predefined constants. The variable must be equal to one of the values that have been predefined for it. Common examples include compass directions (values of NORTH, SOUTH, EAST, and WEST) and the days of the week. Because they are constants, the names of an enum type's fields are in uppercase letters. In the Java programming language, you define an enum type by using the enum keyword. For example, you would specify a days-of-the-week enum type as:
public enum Day { 
There is a presentation available on enums.

IO in Java can be complex. This is a nice overarching tutorial and here is a good description of streams, files, and IO.
