I am a bit confused on how a, c, b is printed.
I originally thought a, c, b, c would be printed because the subList() method would return c, due to the fact that subList's starting value is inclusive, and the first value is c, so it should include the String c.
Why is a, c, b printed but not a, c, b, c?

If fromIndex and toIndex are equal (as is the case in this question), subList returns empty list. This is as per https://docs.oracle.com/javase/8/docs/a ... t-int-int-

As background information; here are some notes by Edsger Dijkstra on why ranges should be expressed as lower <= x < upper
