see a recurring trio and I guess it has something to do with ASCII (although honestly I still haven't figured out why only 3 when I look at those tables) and I don't understand why it "jumps out" immediately 3 and doesn't go from 0 1 2 if x = 0 and increase it after what is being loaded?
Re: for(int x = 0; x <= 4; x++){
The compiler treats the char ' ' as a integer value and adds its value to x.
If you want a space at the end of the line use " ". But why do you want to add a space at the end of a line?
If you don't understand my answer, don't ignore it, ask a question.

Re: for(int x = 0; x <= 4; x++){
Thanks for the reply, it was not my intention to add a space at all. I saw a question like this on some java interview question list and I was a little confused and lost when I saw an answer that was completely different compared to my knowledge achieved so far.
I could not understand where it starts from number 3 and why one triple repeats and the other increases ...? When I put 9 then I get a four at the end.
I have found this ASCII table and there ' is 39 ... https://www.javatpoint.com/java-ascii-table
32
33
34
35
36
37
38
39
40
41
All of this is obviously still too complicated for me for this level I have reached at the moment.

Re: for(int x = 0; x <= 4; x++){
If ' ' has a value of 32
then 0 + 32 is 32
...
then what is 9 + 32?
Then why is the ' ' included in the println call?not my intention to get a gap at all

Re: for(int x = 0; x <= 4; x++){
Honestly, I have no idea. Question number 6.
https://github.com/learning-zone/jav...ons-answers.md
It was simply incomprehensible to me where 3 and not 0,1,2,3 appear ...
Re: for(int x = 0; x <= 4; x++){
To get that output: 0,1,2,3 there would need to bewhere 3 and not 0,1,2,3 appear ...
a "," printed after every number
and the print() method used instead of the println() method which ends the line that is printed and moves to the next line.
With the println method, each number would be on its own line:
3
4
5
...
To get 0,1,2,3 change the method to print() and change the ' ' to ","

Re: for(int x = 0; x <= 4; x++){
Thanks for helping me. I will keep learning Java, I have to admit, all this it confuses me a bit, but I believe that everything will fall into place.
Re: for(int x = 0; x <= 4; x++){
Haaa finally understood. I had to sort out in my head how all this works and it takes its time.
step 1. go to char to ASCII and see how the spacing is essentially 32 numeric value
step 2. repeat the java learning area in which X = 0 is just a sign of where the counting starts and X <= 4 means that there will be a total of 5 steps 0,1,2,3,4
step 3. part x + ' ' means that this numeric value will be incremented as many times as above above specified by the for loop and that's it.
Now I sound like a teacher to myself :-)
