    quick question

    Dear friends,

    how can i add : ch != ' ' ';
    i tried to use that in the code in order to avoid reading the character ' but it didn't work....any idea

    Code:
      for(int k= 0; k < wordsarr[i].length(); k++)
           {  
               ch = wordsarr[i].charAt(k) ;
               
               if(ch != ';' && ch != ',' && ch != '"' && ch != '-' )
               {
                   copywords[i] =    copywords[i] + ch ;
               }
    [ArchAngel added CODE tags]

    In future, it helps us if you post any compiler or runtime errors you get.

    You need to "escape" the sybol by preceding it with a back slash:
    Code:
    public class Test {
            public static void main(String[] args) {
                    char c1 = 'a';
                    if (c1 != '\'') {
                            System.out.println("Not '!");
                    }
            }
    }
    ArchAngel.
    O:-)

    you can not write
    if (c1 != ''')

    if i write c1 = '''; it gives an error that says "empty character literal" so i want to use the unicode for ' to avoid the problem. what is the unicode for '

    thanks

    The forum keeps getting rid of my extra backslash. I've worked out how to keep it now:
    Code:
    public class Test {
            public static void main(String[] args) {
                    char c1 = 'a';
                    if (c1 != '\\'') {
                            System.out.println("Not '!");
                    }
            }
    }
    ArchAngel.
    O:-)
