The Design Problem

• Objective: Have methods for reading/writing data on a higher level. (structured, efficient etc.)

• Problems:

• • There are many enhancements for reading/writing data
  • There are many types of input/output streams
  • If we would include all enhancements in all types of streams we will end up with a lot of duplicated code and it would be hard to add new enhancements or new types of streams
