I am getting an error for
list1 = input.nextLine().split(" ");
I am trying to get rid of the whitespace and replace it with a , in my arrays but i get an incompatible error. would anyone be able to help me out?
example output i get with the input 1 2 3 4 without the split is
[1 2 3 4]
i want
[1,2,3,4]

i think you're mistaken with what you want.

if you have a string that looks like this:


then you don't want to split it, you want to replace the space with comma. there should be replace(..) method in there. keep in mind that split(..) is looking for the space and breaking it into a list, not combining elements and putting a space in between them.

if you want to create a list, please describe what elements you want.

right now you'll get this:
list[0] = 1
list[1] = 2
list[2] = 3
list[3] = 4

do you want this?

list[0] = 1
list[1] = ,
list[2] = 2
list[3] = ,
...

or are you complaining about toString()'s output? you can simply write your own. instead of System.out.println(list), iterate over the list and print each element along with a corresponding comma. i think apache string utils has something for this but i could be wrong.

im trying to trade the white space for a , so my output looks like [1,2,3,4] rather than [1 2 3 4]

ok, so your list is fine and you're just complaining about toString(). two ways to handle it.

1) as i described earlier, create your own function to do it precisely the way you want
2) more of a hack, but you can do something like this: System.out.println(list.toString().replace(' ', ','));
i don't remember the method signature, but essentially you wanna call toString() yourself then replace space with comma before printing it.

#2 worked perfectly for me thank you!
