Different methods for different types

As a subtle hint for solving this problem: The comma and the period have different meanings for different countries, when talking about numbers. Pay extra attention to the express, -albeit- mandatory, period requirement mentioned in the exercise.

After 3 good days of about 5 hours per day, I get it right😭 We will always emerge victorious, every single time!

well F. I spent a whole day learning regex and matching expressions. while working on a converted character string and the codegym answer cuts my code in half simply by embracing the errors thrown by incorrect casting. I came the long way on this one, and ill say even if your way is inefficient you should still follow through because you will learn more, and be more likely to remember the shorter way when you do look at it after you finish.

Good exercise for how to use exceptions and efficient logic

When I first started CodeGym, I think it would often say something like "5700 people have completed this task" but now it's only 1274. People quitting? Also, I feel kind of bad because at the beginning I was getting everything in one attempt and it was better than average. Now it takes me more tries than the average for most of these tasks. If it takes me more tries than average, is that a bad sign for becoming a java developer?

If the number has all zeroes after the decimal it should be considered as a Double, and not Integer. (eg 22.000)

I was so thrilled with my solution to this problem, and I wanted to see how I shaped up against the solution on CodeGym, so I downloaded their solution. What I did in 69 lines of code they did in only 53. Disappointing, but their logic was the same, they just had tighter code. For example, I had two try-catch blocks instead of just one, and three if-else statements, instead of just two. It was good to see how I could improve, and wish I had DLed more solutions in the past, now.
