How can I only return a part of my String method?

I have a String method that I would like to only return the part after the if statement but not the else! I have already tried a try & catch but didn't work either. Is that possible?

PS.This is my first time using stackoverflow.

String split() {
    String one = "", two = "";

        int index = tableFields.indexOf("(");
        if (index > 0){
        one = tableFields.substring(0, index);
        two = tableFields.substring(index + 1,
                tableFields.length() - 1);
        }
        else {
            System.out.println("error");
        }
        return "`" + one + "`" + " "+  two;
}

You can throw an exception in the else, or return null.

Something like

else {
    throw new IllegalStateException("Can't split");
}

or

else {
    return null;
}

http://www.tutorialspoint.com/java/java_builtin_exceptions.htm provides a list of some built-in exceptions that might be useful, otherwise you could write your own.

You can return both in the else and the if.

if (index > 0)
{
    one = tableFields.substring(0, index);
    two = tableFields.substring(index + 1, tableFields.length() - 1);
    return "`" + one + "`" + " "+  two;
}
else 
{
    System.out.println("error");
    return null;
}
