Need help in getting started

Hi..

I am gonna make a mail user agent for a LAN. Using java. I was confused about what to use. Should I use applets, or start coding without them, making use of windowlistener interfaces etc ? I dont know if i should use applets, and if i should could u please tell me why applets are preferable.

Thanks,
Hanaa

Thanks.
I seem to have another problem. Only recently, I installed java update 7.
There's this file called myframe.java which has a public class 'myframe'. Another file 'keydemo.java' extends the class myframe. This program worked on update 2. On this new version, i try to compile the second file, that is keydemo.java. I get an error saying it 'cannot find the symbol myframe'. Could anyone help please... I tried the same with many other such files, none of them seem to be working.

Thanks again,
Hanaa.

Okay.. I tried the following and it worked. (2ndsem is the directory containing both the files in question - keydemo.java and myframe.java. )


C:\hanaa\2ndsem> javac -classpath C:\hanaa\2ndsem keydemo.java

Yet, I wanna know why it doesnt work like it used to with the older version, and also why this worked. Would someone be kind and tell me why.

Thanks,
Hanaa.

Which version did it work on? I don't think it should have worked on any Java version at all? Are you sure you didn't move the files?

[hanaa]

Yes.. I am sure. Back then, I used 1.6.0_02. Now, i use 1.6.0_07. I was in my second semester then, and all the base and derived class' files worked that way. I dont see why it shouldn't now. Both the files are in the same directory.

On the older version, it worked without the -classpath option. Below is what I used then.

C:\hanaa\2ndsem> javac keydemo.java

Either you added a package declaration that wasn't there or one of the .class files got removed/deleted.

I didnt add any package declaration :( And i checked, the .class file of the base class is there in that directory only. I cant seem to move on unless I understand why it isn't working. :(
