Question about the task Task about algorithms
Java Syntax, Level 9, Lesson 11
Resolved
Why does the data read loop read a "null" as the last element? (After the last of all item of the inputlist.) But only in some cases, and in other cases doesn't.A data read loop threw a nullPointerException in some cases. The input list contained numbers and strings mixedly, but I read them all as strings one after the other, into a string ArrayList: while (true) { String s = reader.readLine(); if (s.isEmpty()) break;

Question about the task Static modifiers: part 2

Resolved
My task works, but this is nonsensical ?Why did I have to specify Solution.A = Integer.parseInt etc...... instead of just being able to specify A = Integer.parseInt etc...... ? A is a public Solution wide variable. Also, why did they put in public static final int MIN = min(A, B); if you can't just print MIN (which already did the c

Question about the task Static modifiers: part 1
Java Core, Level 5, Lesson 9

It works, but why would this make ANY difference, compared to just doing it like we've done it before ?In the Main method, instead of in a Static block, whatever that means. Both would populate the list the same way.

Solution Grader is Wrong How is it possible that every requirement is wrong, when the program clearly generates the output defined in the problem statement? I mean, even "The program must not read data from the keyboard" is a fail? I also tried it by just having 10 println() statements, got the same results.
