getters&setters

[ceyesuma]

How do you use methods as args? I can not seem to get the string or file stored in the getters and setters to work as args for the printWriter.etc. Unless something else in this code is causing it. all the getters and setters work everywher else

sorry i could not follow you... probably i m too sleepy... are you trying to say your constructor is not actually working bcoz set/get methods are not working? as i can't see the methods, i can't tell u why and what is not working... li'l advice for u... remove "throws Exception" clause... it will give you at least some IMPORTANT error msg by which u can debug ur program easily.

[stultuske]

are you sure you've actually stored data in the object before using the getter?

[ceyesuma]

Yes there is another class and it has all the variable .But I need to get those values and create a file with the value in one of the getters of another class
FileWriter file = new File(getStatusFile(),true) and that getStatusFile should return the name of the file to create but it creates a file called "getStatusFile" instead. Any Help?
Thanks

[orko]

well... getStatusFile() will only return something if it has something to return, otherwise it may or may not return null based upon your code.
so plz check if you have set up your value correctly at the moment you are calling your get method. Having the same variable in your super class does not guarantee any value to be there. Besides, if your values are already set, then what is the purpose of getting the same value and setting it again?
Your question has insufficient information for any one to solve it... but you still can do one thing... print the returned value of getStatusFile(), and thus go back, print the same thing in the super constructor... you can find out what is wrong.

[ceyesuma]

I have to tasks to write to a StatusFile and to a LogFile. When I insert getStatusFile() for instance, into

FileWriter fw=new FileWriter(getStatusFile(),true);

I would like it to write to the file that was created in the ProcessCard.class in which I am trying to call getStatusFile() and whatever file that happens to be there it will write to it.
Is This possible?
