Working through Exercism.io pathways and documenting it along the way.

This is a really good website to learn and progress through JAVA, it helped me learn new ideas and refresh on my old ones.

Greeter was pretty straight forward. Just return the expected string. https://github.com/airbuff/Exercism.io/blob/main/Java/Greeter.java

Lasagna involved little manipulation of the passed in parameters. https://github.com/airbuff/Exercism.io/blob/main/Java/Lasagna.java

I did this with a classic flow chart however it can be done a lot easier than I've implemented it. https://github.com/airbuff/Exercism.io/blob/main/Java/AnnalynsInfiltration.java
This is the flow chart I used and following the instructions it's pretty clear what it wants to pass your code.
While doing the exercises I realised completing one exercise in one section completes in another seciton too, thought that was pretty neat. (I might learn to do that relational entries??...)

Reverse String is a method straight out of the library which was news to me. My implementation would've involved a array with the length of the input then spit the values in the array in reverse order. But I found the method so, reiterating my point it's a good website. https://exercism.org/tracks/java/exercises/reverse-string/edit

Microblog this exercise has taught me the most so far, I researched Unicode and Codepoints which I thought were trivial and didn't give much thought to initially. I found out storing different characters based on codepoints is the new standards and unicode determines the byte size. To do this one i initialised an array measured its size using codepoint and followed the bouncing ball. https://github.com/airbuff/Exercism.io/blob/main/Java/MicroBlog.java
