Number pattern

Question

For(int i=0;i<=5;i++){
For(int j=0;j<=i;j++){
}
Sout(i);
Hi all
I wants to know how this for loop is working I try to search in internet but no answer so any one help me out in this
Thanks in advance

Answer 1

I think it works a little bit like this (it's just a theory)
x is the kind of number it will output (1, 2, 3, 4, etc) and y is the amount of times it will output the number.

so if x = 0 and y = 0 it will output 0 only 1 time, because both x and y are equal, but if x' value is 1, because it came from 0 to 1, it is 1 higher than y, so it will output 1 two times, and because 2 is 3 numbers higher, it will output it 4 times, but if you make the numbers negative and decrease instead of increase, it will just work the same, but it will output a "-" for the numbers, because it's negative.

if you set x = 0 and y = 1, it won't output 0 , because it's 1 less than y and will be output 0 times

if you set x = 0 and y = -1, it won't output -1, because x can't, but it will start outputting 0 two times, because 0 is 1 higher than -1

*edit* : I'm not sure if I'm correct, but i think I'm pretty close to how it really works

Answer 2

at first, you forgot a "}"
and maybe this will work, even if it doesn't give an output:
For(int i=0;i<=5;i++){
For(int j=0;j<=i;j++){
Sout(i);
}
}
and, tabs will help you with understanding where your mistakes are, i mean if you used this
For(int i=0;i<=5;i++){
For(int j=0;j<=i;j++){
}
Sout(i);
you could have seen very fast that you missed a curly bracket

Answer 3

Hi roel
Ya I missed one curly bracket,but I need to know how the for loop is working here can you pls explain me.

Answer 4

in for-loops, for has to be written without uppercase "F"

Answer 5

this for an example (because i don't understand the function of "Sout") a fully working code where 0 is written 1 time, 1 is written 2 times and so on
public class Program
{
public static void main(String[] args) {
for(int i=0;i<=5;i++){
for(int j=0;j<=i;j++){
System.out.println(i);
}
}
}
}

Answer 6

Yes bro but how the output is working that is what I want to know!
