    Question about the task Sorting even numbers from a file
    Java Core, Level 3, Lesson 11
    Archived
    Console won't stop readingThe problem for me is that when I enter the file name and hit enter the console just continues to read until I stop the program. I cannot find anything in my code that would make this happen as I only user the reader object once. I'm stumped.

    Question about the task Three numbers
    Java Syntax, Level 4, Lesson 6
    Under discussion
    the indexes you should return are "1, 2, or 3," not "0, 1, or 2" as you might expectSpent a lot of time struggling to figure out how my code could be wrong before realizing that the solution did not want a zero-based index. Now that I realize it, the example does make it clear (in 466 example, the solution is "1"), but I did not read carefully enough and wasted at least a half hour

    I have general question not about this task. If we want synchronized something in some method can we always use word synchronized after access modifiers in method instead of synchronized block? I am not sure but i suppose it is much more convenient.
