making a file directory in java

[kay lin]

Hi all:
I would like to make a file direcotory in Java, so I did was the following

 
 boolean a =    new File("C:\\jbproject\\AJJavaModelApplicationOCT7.bkp\\JavaModelApplicationAAAEJB\\META-INF\\").mkdir();
 
        if (a)
            System.out.println("made dir");
        else
            System.out.println("didnt make dir");
   
 
 

C:\\jbproject\\AJJavaModelApplicationOCT7.bkp\\JavaModelApplicationAAAEJB\\META-INF\\ is the name of the directory I want,

but when i run the program, it is not making the file directory..can somebody let me know what I am doing wrong??

Thanks

That looks OK, assuming that all the directories but the META-INF one already exist. Are you sure you typed that nasty pathname correctly?

You might try printing the value of

new File("C:\\jbproject\\AJJavaModelApplicationOCT7.bkp\\JavaModelApplicationAAAEJB\\").exists();

it should print "true".

If not all the directories already exist, you need to create them one at a time from the top down.

I see..I think i might know what my problem is...
the \\JavaModelApplicationAAAEJB\\ doesnt exit
so I guess I will have to create that directory first..and then the \\META-INF\\ correct? plz let me know

many thanks

Yes, that's right.

If I remember correctly, there is also a mkdirs() method that will create all the directories in the path.
