EOF methode

[Dipke]

Hello,

I am reading a text file using FileReader and BufferedReader.
Is there a way a checking the EOF ?

I set an EOF attrubute to true when

br = BufferedReader(fr);
br.readLine() == null;

.

Is there another way of checking the EOF
ex : br.EOF;

thanks

Did you find such method in the API documentation?

kind regards,

Jos

ps. Java (nor C, nor C++) can predict an eof-condition. Pascal used to be able to do this.

Hello,
No i did not, but perhaps there is a method with another name that does the job.
Or there is another way of checking.

try{
while(true){
// code here
}
}
catch(EOFException e){}

Thanks for the reply

Thanks for the reply

The code in the previous reply doesn't always work, i.e. there are methods that return -1 or null when they have bumped into an end of file and no exception is thrown. Read the API documentation for the InputStream and Reader classes instead.

kind regards,

Thanks jos,

I am still using my code that is working.

br.readLine() == null;

I am used to work with VB en RealStudio.
There is an EOF.
Therefore i was just wondering if there was a similar thing in Java.

Kind regards

In Java there is no such thing as an 'end of file' character and nor is there physically one in a file. There is an end of file condition and it is shown to you by the return value of the method if it can do so. Methods that can't return such a 'sentinel' value have to throw en EndOfFileException. Just play the game by the rules and everything will be fine.
