String split in java does not work?

Question

I split this String by space : String input = ":-) :) :o) :] :3 :c) :> =] 8) =) :} :^)"; (space between emoticons)

And result is:

:-)?:)?:o)?:]?:3?:c)?:>
=]

8)

=)?:}?:^)

There are some strange characters in the results. I don't know why. Please help me.

Here is the code:

fileReader = new BufferedReader(new FileReader("emoticon.txt"));
String line = "";
while ((line = fileReader.readLine()) != null){
    String[] icons = parts[0].split("\\s+");
    ....
}

Thank for any advices. Here is emoticon file:

Answer 1

String input = ":-) :) :o) :] :3 :c) :> =] 8) =) :} :^)";
String[] similies = input.split(" ");
for (String simili : similies) {
    System.out.println(simili);
}

This works fine. Output :

:-)
:)
:o)
:]
:3
:c)
:>
=]
8)
=)
:}
:^)

and in case if there is any tab/newline/spaces and you wnat to split, in that case you can use

input.split("\\s+"); 

in your example there is few more charaters are their like  and non breaking whitespaces so you have to explicitly handle these type of charater. Here is the code:

public static void main(final String[] args) throws Exception {
    BufferedReader fileReader = new BufferedReader(new FileReader("emoticon.txt"));
    String line = "";
    while ((line = fileReader.readLine()) != null) {
        line = line.replaceAll("Â", "");
        line = line.replace("" + ((char) 160), " ");
            System.out.println("line: " + line);
        String[] icons = line.split("\\s+");
        for (String icon : icons) {
            System.out.println(icon);
        }
        System.out.println("=======================");
    }
}
