java - Print Elements of ArrayList in order of input string -

what trying is, input string user. add arraylist since have play characters later. first want print contents of arraylist in order check in their. here code

public static void main(string[] args) {     scanner sc = new scanner(system.in);     list <string> vowels = new arraylist<string>();     system.out.println("what string? ");     string abc = sc.nextline();     int n = abc.length();     for(int i=0; <= n-1 ; i++)     {         vowels.add(sc.nextline());     }      for(int j=0; j< vowels.size();j++)         system.out.println(vowels.get(j));  } 

it not printing or not showing error. highly appreciated.

here problem:

for(int i=0; <= n-1 ; i++) {     vowels.add(sc.nextline());                ^ } 

"it not printing anything" because waiting input

what need is:

public static void main(string[] args) {     scanner sc = new scanner(system.in);     list <string> vowels = new arraylist<string>();     system.out.println("what string? ");     string abc = sc.nextline();     int n = abc.length();     for(int i=0; < n ; i++)     {         vowels.add(new stringbuilder().append("").append(abc.charat(i)).tostring());     }      for(int j=0; j< vowels.size();j++)         system.out.print(vowels.get(j)); } 

input : burger

output: burger

if want output [b, u, r, g, e, r], do:

system.out.println(vowels); //without loop
