Create a seperate Project with some classes and then you can import these classes like you import any other class:


The only difference is that you will be importing your classes with their packages.
You can take the .class files (in their folder/package) or create a jar file with the classes. Then add that to the classpath of the project you want them to be used.

thanks lots i will try that...

Dear,

Create .jar of those classes you want to use them in different projects and append the entry of .jar file CLASSPATH environment variable.

PS:
You can place .jar files in \jdk1.6.0\jre\lib\ext . (shared folder of jvm - am I?, Mr. Ancient Dragon.).
