This program gathers input from the console as a string, then determines the base of the input. It then converts binary/octal/decimal/hexadecimal values to BigInteger for storage. It can then convert to any of the other base types as required.
- Interfaces and abstract classes in Java
- How to store data as a common type that can be shared between classes (
BigInteger) - How to the
Factorydesign pattern to build various<<interface>>objects - How to convert between bases one byte at a time
- Two's complement
- UML notation
- Data structures and data management in Java
- StringBuilder class
- Original internal representation was binary bytes, but this caused issues due to Java's interger types being signed
- To overcome issues with signed representation, I looked into using a wider type to prevent overflow, but this created great challenges when joining the individual bytes back together
- Case sensitivity caused the system to be unstable (this has been addressed and fixed)
- Design choices led to potential for null pointers (this has been addessed with null checks)
- Finish the decimal base class implementation (last base class)
- Follow up on issue with returning unsigned binary bytes
- Investigate alternative common data storage options such as BigInteger
- Add support for hex strings with spaces between individual bytes (2 digits) as input
