Question about the task Plan to conquer the world
Java Syntax, Level 3, Lesson 8

finally!!Hey guys! Don't forget to import necessary classes from the java.io. package. Plus, if you have a look at the console input you'll see that they passed the age as the first value, and only after that they entered a name. So you have to adapt your code to this order. I hope this will work for you 😊

Where can I see other people's solutions for problems that I have completed?Obviously, once you solve a problem, that is great and all, but in order to improve coding it would be nice to see how other people solved it to compare styles and pick up new ideas for future similar problems.
