Why the program doesn't correct my activities? From level 3, where you have to download IntelliJ IDEA, every time I solve an activity the page does not correct me. And in the IntelliJ IDEA program I cannot solve the tasks because they are the ones I have already done. Please help me because I cant do anything!

Question about the task Finding data inside a file
Java Core, Level 8, Lesson 11
Resolved
I have the solution but I do not understand it Questions 1) what do they mean with the 'specified id' in this context? It seems like we have to create a method in which you can pass the int id? 2) what is this args[0] in this context?

What are the passing requirements?I fail at: The getNumbers method must return the array of numbers that satisfy the task conditions. I'm guessing it is a time issue. What kind of numbers do we have to hit to pass?

Things are getting out of control I had several working solutions and none of them was accepted. My solution right now looks almost as the one in the answer. The only difference I see, is that I am using map while CG is using their own object. So, what is wrong here? Is my solution wrong or it just does not follow the standards of C
