Question

I have a list of Strings in Java, I would to create an array of Chars instead. Is there a quick and dirty way to do this?

Answer 1

If you mean to go from List<String> to char[] this may be useful

public static char[] convertStringListToChars( List<String> stringList ) {
   StringBuilder sb = new StringBuilder();
   for ( String x : stringList ) {
      sb.append( x );
   }
   return sb.toCharArray();
}

Or if it’s List<String> to char[][]

public static char[][] convertStringListToChars( List<String> stringList ) {
   char[][] chars = new char[ stringList.size() ][];
   for ( int i = 0; i < stringList.size(); i++ ) {
      chars[i] = stringList.get( i ).toCharArray();
   }
   return chars;
}
