Thread: I cant work it out!!!

Can anyone please tell me why this code is not working?? plz would be much appriciated

Suggestions to fix by netbeans are:
cannot find symbol
symbol: class Location
location: class javaapplication10.Stations

cannot find symbol
symbol: class Line
location: class javaapplication10.Stations

Sorry i dont know what you mean like this .........

The problem seems to be with the Location and the line

Your IDE is hiding the full text of the error message.
Can you compile the source with the javac compiler to get the full text of the error message?

Why doesn't the IDE find the definitions for the Location and Line class?

yay lol......

Try separating the definitions of all the classes to separate files with one class per file.

i cant m8 i wouldnt know how - its taken all i got to do what ive done lol sorry m8 but thanks anyway

There shouldn't be any problem selecting each of the class definitions from the class statement through the ending } and copying it to a new file.

Who taught you to put all the class definitions in one file?
That is not how it is normally done.

OMG snow guy ive got rid of the location issues because of the one bracket as u said!!!! been looking for hours and couldnt see it.

Still cant get it to accept the line class even within the station class....but ty anyway

Post your error messages if you want help with them.

Take Line/Location/Station out as seperate java class files and ur program worked for me.. something like

package javaapplication10;
 
public class Line {
 
    String lname;
 
    public Line(String String) {
        lname = String;
    }
}

It is very hard to assist you because your code is like so unreadable. In order for the code to be easily readable, please, before pasting your code into the forum, type [highlight = java] and then insert code and finally before posting it, add [/java] at the end. why is this instruction so hard to get?

Hello tuts73, I have a very similar task to complete but im sturrgling to calculate the bearing. Have you managed to achieve this?
