Radians
Run my solution on repl.it!
This problem was rather simple to implement, although, it did trip me up when it specified that everything must be in terms of PI. I didn't get that essentially you have to divide the converted radians to PI, so it helps to remember the meaning of that sentence (but I did later notice and correct this).
Otherwise, implementation is self explanatory and requires no extraneous thought. For those not aware, the method Math.toRadians can be used to convert degrees to radians easily, which is very important to remember should one be programming in JCreator, or an IDE with no built-in/enabled code completion/code intelligence plugins.
I recommend using String.format for this problem deeply, as it helps with rounding off the decimal radians measure quickly.
