Question

I am new to java and don’t know why I am getting this error or how to fix it. Any help please?

Word.java:42: cannot find symbol

symbol : method length()

location: class char[]

  char finalLetter = letters.charAt(letters.length()-1);
                              ^               ^

Thanks~~

Answer 1

It looks like letters is a char[]. You need to have a String object to do that.

so either convert it to a String

String str = new String(letters);
char finalLetter = str.charAt(str.length() - 1);

or use directly as a char[]

char finalLetter = letters[letters.length - 1];
