"Extensible Systems with Type Classes" has no solutions

"Type Parameter Constraints" is incomplete

ClassExercises/Solution-4.scala lose one "if" logic

   if(h < 0 || **(h==0 && m<0)**) {
        new SimpleTime(0, 0)
    }else if(m >= 0) {
      new SimpleTime(h, m)
    }
    else new SimpleTime(h-1 ,60+m)

test:

val st4 = new SimpleTime(9, 30).subtract(new SimpleTime(9, 50))
st4.hours is 0
st4.minutes is 0

"Pattern Matching with Tuples" has no solutions

"Handling Non-Values with Option" is incomplete

"References and Mutability" has no solutions

"Logging" has no solutions

"Error Reporting with Either" does not appear to have completed solutions

How is the expected variable getting any value? in AddMultiply.scala

How is the "expected" variable in (result == expected) getting any value? If the "result" val is being made equal to "expected", where is expected picking up any value at all? very confusing

def test(x:Int, y:Double,
14 s:String, expected:Double):Unit = {
15 val result = addMultiply(x, y, s)
16 assert(result == expected,
17 "Expected " + expected +
18 " Got " + result)
19 println("result: " + result)
20 }

Probably need AtomicTest.scala and any other items necessary for standalone build

I am not sure, how to execute Solutions

Issue with setting CLASSPATH, missing code/ directory

Hi,

I'm setting up scala on a mac. In the setup chapter of the ebook it says to

cd ~/AtomicScala/code

However, there is no subdirectory called code in the latest solutions download:
https://github.com/AtomicScala/atomic-scala-solutions/archive/master.zip

I can't seem to proceed with the CLASSPATH section of the Mac setup without this.
Thanks
