Course Java Syntax Zero - Lecture: Best course about the fundamentals of programming

1. Summary of Level 1

Congratulations! You've completed the first level on CodeGym! Just one level and you've already mastered a bunch of important and interesting stuff. Good work!

You learned about:

Variables;
Displaying text on the screen;
Int and String types;
You learned the difference between compiling in Java and other languages;
Adding comments in code and why we need them.

Excellent! Of course, the levels that follow won't be as easy, but they will grow more difficult gradually. The same goes for the exercises.

It's like going to the gym: we add weights little by little, and 6 months later, the beginner can do 220 lbs on the bench press.

Boring lessons are so 21st century! Can you imagine writing in chalk on a blackboard! Nothing had changed since the 1400s. I suppose there were dinosaurs still roaming the streets then.

You are advancing to the next level! 😉

The calculation of the average attempts appears to be faulty. My guess is: If there are two tasks within a lesson, it counts the attempts but does not increase the number of tasks with which it ought to be divided with by the second task.

public class Solution { public static void main(String[] args) { int x = 2; int y = 12; // y = x * y; y = x + y; x = y - x; y = y - x; System.out.println(x); System.out.println(y); } }

public class Solution { public static void main(String[] args) { int x = 2; int y = 12; // y = x * y; // y = x + y; x = y - x; y = y - x; System.out.println(x+y); System.out.println(y); } }

comments some mention line // System.out.print("two"); System.out.print(b); System.out.print(" plus "); // System.out.print(" minus "); System.out.print(a); // System.out.print("three"); System.out.print(" is equal to "); // System.out.print(" equals "); // System.out.print("five"); System.out.print(a + b);

just uncomment this below line y = x + y;

Pro tip: use Ctrl + / to quickly comment/uncomment lines! This shortcut works in most editors including VSCode and IntelliJ
