/prog/ - Java won't work

Name: Anonymous 2010-09-23 19:47

why?



import java.text.DecimalFormat;

public class Internetcosts

{

    public static void main(String[] args)

    {

        int hours = 10;

        double packa = 9.95;

        double packb = 13.95;

        double packc = 19.95;

        

        DecimalFormat formatter = new DecimalFormat("#00.00");

        

        System.out.print("Hours     Pack A     Pack B     Pack C");

        System.out.print("-----------------------------");

        

process_hours:

        System.out.print(formatter.format(packa + 2));

        System.out.print(formatter.format(packb + 1));

        System.out.print(formatter.format(packc);

        ++hours;

        if(hours <= 50)

            goto process_hours;

    }

}

If only you were capable of reading compiler error messages.

No wonder you get errors. Your grammar fails my parser.

$ javac Internetcosts.java

Internetcosts.java:19: ')' expected

        System.out.print(formatter.format(packc);

                                                ^

Internetcosts.java:22: illegal start of expression

                             goto process_hours;

                             ^

Internetcosts.java:22: not a statement

                             goto process_hours;

                                  ^

3 errors

1. You forgot a ).
2,3. Java does not support the goto statement.

Here, apply this:

16a17

      while (true) {

19c20

<         System.out.print(formatter.format(packc);

---

          System.out.print(formatter.format(packc));

21,22c22,25

<                        if(hours <= 50)

<                            goto process_hours;

---

          if(hours <= 50) {

              break process_hours;

          }

      }

But i want to use gotos. They are alot better.

process_hours:
...
goto process_hours;

You are either a troll or a student of a better world than this one (on the other hand, "GOTO Considered Harmful").

One obvious problem is that you forgot to close the 19th line's parentheses. Changing the does-not-work goto into a loop ...

do

{

   System.out.print(formatter.format(packa + 2));

   System.out.print(formatter.format(packb + 1));

   System.out.print(formatter.format(packc));

   ++hours;

}

while(hours <= 50);

allows Java to accept the source code, though its output is still sad.

Future concerns: packa packb do not stack the addition of 2 and 1, respectively, each print as I am assuming that is what you want. They discard the results of the addition after the print statement.

And we're done here. All future posts on this thread should include sage and, optionally, " >>7 YHBT."

Java doesn't recognize a literal goto statement.

I now see why people say Java sucks then.

There are many reasons why Java sucks, a lack of a goto statement isn't really one of them.

There are many reasons why Java is a bad language but not supporting a goto statement is a new one on me.

Java made goto popular by not having it

The next version of Java will include CallWithCurrentEnterpriseContinuation(new FunctionWrapper(x)) where x is an object of class ContinuationReceiver which implements the ContinuationCallee interface which requires you to define methods isAvailable(), isItReallyAvailable(), aboutToCallIt(), targetCalleeMethod() and itsDoneJustSoYouKnow(), but don't worry because you can inherit two of them from BaseContinuationReceiver.

My University course involves lots of Java. This makes me sad.
On the other hand, my library has the Wizard book and I can program whatever I want outside of my course.

Interesting, I should go see if I can find the Wizard book as well in my own uni library, maybe I'll find it at a good price.

I don't think you even know what a library is.
