Console won't stop reading The 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 expect Spent 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

Cannot pass the verification I tried two methods to limit the time to 10 seconds, but after a lot of googling I can't find anyway to limit the memory use. I tested in the main, either way works for the time control, but the verification still times out. Any suggestions please? Thanks in advance.
