> string str - "practical example is always needed"
Try to finish this:
        String str = "practical example is always needed";
        char search = 'c';
        int occurrence = 0;
        for(int i = 0; i < str.length(); i++) {
            // Use a method from the String-class to get a
            // char from a specific location in the String.
            // See: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
        System.out.println("Occerrence of char "+search+" in \""+str+"\" is: "+occurrence);
