I don't know how to do the exercises of CodeGym

Thank you very much. I thought I didn't have to search the internet. So I couldn't understand… I was whipped. Thank you for your words. now it will be easier :)

You learn by practising! Basically, they want you to get user input using a BufferedReader or Scanner. Then assign those values to the correct variables. Finally, print out a message that has the name and number of years. The statement looks like this: (name + "will take ..." + years + " years...") I hope this helps.

That's the way CodeGym wants you to learn, and I admit that it's pretty confusing sometimes. Understand that looking for a solution on Internet is one of the main thing about being a coder. There is no shame to it, try your best on the exercise, look at the solution if needed (on Google or straight in the Help panel), take your time to understand the most of it, go back to your code and write it with the new principle you have learnt. Don't forget to have fun anyway, those are like puzzles after all :) !
