I must tell you. A programming language that has no for loop doesn't have much. It is so very useful. And Pascal—the favorite language of high school students, college students, and the entire educational system on Planet Earth in the 20th century—was no exception. We present for your consideration verbose and precise Pascal code for loops and their literal translation into our favorite Java.

There's no longer any point in hiding this terrible secret from you: From now until the end of your programming life, you'll have to use the for loop. You can't escape this. Take my word for it. And if that's the case, why not learn to use this ubiquitous tool like a virtuoso? Starting right now: We have 5 tasks about loops.

The wise professor is with us once again with his useful links. This time his suggestions are focused on strings, visibility, branching statements, and logical operators. These materials can significantly facilitate your understanding of new topics. That is, of course, if you aren't too lazy to read everything, break it down into atoms, and reinforce your knowledge through practical exercises.

Did you know that before the final power lift and transition to Level 5, you need to relax a bit and watch a video from the "Do You Know?" series. This isn't just entertainment. It's part of the comprehensive curriculum developed by the pedagogical board at the secret CodeGym center. The video is dedicated to the technologies and progress achieved by mankind.

Complete 4 tasks and get a pass to Level 5... Actually, that's not quite right. But in any case, the more tasks you complete, the more rapid and obvious will be your progress. Your attention, please: These tasks involve a solution in IntelliJ IDEA. Data input, branching, methods, and loops — we're putting into practice what we've already covered.
