How to split a String in an array to individual char?

Question

I have this simple code that split an input and put it in array of String:

Scanner sc = new Scanner(System.in);
    String s = sc.nextLine();
    String[] arraySentence = s.split(" ");
    for (int i = 0; i<arraySentence.length; i++) {
        arraySentence[i].toCharArray();

        System.out.println(arraySentence[i].toCharArray());
    }

my focus is to manage every character of every single word into the array.

For example if I pass: "now we only have"

the string from input becomes: arraySentence{now, we, only, have} and I want to be able to take the "n" after the "o" then "w", etc.

How can do it? Thanks

Here's another way to achieve what you want to do.

public static void main(String[] args) {
     ArrayList<char[]> list = new ArrayList<>();

     String s = "now we only have";
     String[] arraySentence = s.split(" ");

     for(String str : arraySentence) {
         list.add(str.toCharArray());
     }

     list.forEach(arr -> System.out.println(Arrays.toString(arr)));
}

list contains char arrays. Do whatever you want to do with them...

Output

[n, o, w]
[w, e]
[o, n, l, y]
[h, a, v, e]

I hope I understood your question correctly, if not please leave a comment to be able to modify and correct. Inside your loop you can use the one of following snippet based on your needs.

char[] arr = arraySentence[i].toCharArray();
//in case you need n - o  - w
for(int i=0;i<arr.length;i++){
 System.out.print(arr[i]);
}

//also you can do this too 
for(char c: arr){
 System.out.print(arr[i]);
}
//in case you need w - o - n
for(int i=arr.length-1;i>=0;i--){
 System.out.print(arr[i]);
}

correct, thanks I was able to do that, but i forgot to put this instrution : System.out.print(arr[blu]+ " \n "); so I never see the correct result.
