Java String Project Bases and Decimals

Create a class called BaseMaster (spelled exactly like this)

 

//helper functions

the isNumeric() method returns true if every digit is an integer . It also allows for a single ‘.’ to represent a decimal point.

 

 

example call return value
isNumeric("3.1") true
isNumeric("3.1.1") false
isNumeric("3a") true (assume base 16)
 isNumeric("3D")  true (assume base 16)

To get A+, you need to make base10toOtherBase() support bases 2-10 AND base 16

Powerpoint Projects

Each of you will be responsible for creating a powerpoint project .  Cover all topics and key vocabulary in the book. Your powerpoint should probably be 10-15 slides. It should include images and, if possible, any good videos that we can watch.

Powerpoint guidelines
  • visible text (no dark text on dark background)
  • keep the wording as little as possible
    • rule of thumb: If it’s too much text for audience to read, then it shouldn’t be there. Instead you should summarize key points with text and say out loud the extra info and details
  • animations/visuals are always the best way to go

 

These must be completed by
