Blocage sur l'exercice : task04.task0434 - T - java help on CodeGym

Bonjour à tous, j'ai presque fini cet algorithme mais j'ai juste le premier chiffre de chaque ligne ( à partir de la seconde ligne) se retrouve à la fin de la ligne précédente. Par exemple : 1 2 3 4 5 6 7 8 9 10 2 <= 4 6 8 10 12 14 16 18 20 3 <= 6 9 12 15 18 21 24 27 30 4 <= 8 12 16 20 24 28 32 36 40 5 <= 10 15 20 25 30 35 40 45 50 6 <= 12 18 24 30 36 42 48 54 60 7 <= 14 21 28 35 42 49 56 63 70 8 <= 16 24 32 40 48 56 64 72 80 9 <= 18 27 36 45 54 63 72 81 90 10 <= 20 30 40 50 60 70 80 90 100 Je ne sais pas comment y remédier, si quelqu'un pourrait me débloquer ça serait cool. Merci d'avance les amis !!! Hi, i almost finished this algorithm but i just have the first digit of each row (starting from the second row) ends up at the end of the previous row. For example : 1 2 3 4 5 6 7 8 9 10 2 <= 4 6 8 10 12 14 16 18 20 3 <= 6 9 12 15 18 21 24 27 30 4 <= 8 12 16 20 24 28 32 36 40 5 <= 10 15 20 25 30 35 40 45 50 6 <= 12 18 24 30 36 42 48 54 60 7 <= 14 21 28 35 42 49 56 63 70 8 <= 16 24 32 40 48 56 64 72 80 9 <= 18 27 36 45 54 63 72 81 90 10 <= 20 30 40 50 60 70 80 90 100 I don't know how to fix it, if someone could unblock me that would be cool. Thank you in advance friends !!!

Thanks for your answers guys, I don't know why I'm going to see it complicated when we can make it simple. 😂😂😂

solution

#1 don't use static variables unless instructed to. It is bad practice in the real world, and 90% is an automatic fail on Codegym. Move the variables on lines 11-13 to inside the main method where they should be because they are only local variables. Imagine the problem: You need to print ten rows of ten columns. Another way of putting this is that you need 10 outputs for ten lines. And in code you would want an outer loop responsible for 10 lines, and an inner loop responsible for 10 outputs on each of those lines. So: Loop1 cycle 1: loop2 cycle 1-10: print # # # # # # # # # # new line Loop1 cycle 2: loop2 cycle 1-10: print # # # # # # # # # # new line Loop1 cycle 3: loop2 cycle 1-10: print # # # # # # # # # # new line ect.... The code above almost has it, but it goes too far. The main problem is that 24, the line responsible for creating a new row, also prints a number. As you have noticed, this number appears at the end of a line it shouldn't, but that is because the computer is only doing exactly what it is programmed to do.

Wow, that's some complicated piece of code ;) The inner while loop is not necessary as the outer already does that job. Instead you should just reset num1, increment num2 and go to a new line. And you should check if num2 is <10, otherwise break.

if (num1 == 10 && num2 < 10) {
    System.out.println();
    num1 = 0;
    num2++;
}

But as said, that's not easy code and not understandable at first view. Why not just nest two for loops that count from 1 to 10?
