Thank you,
Hung Vo.(This is for windows. Make appropriate changes for other environments)
1. Make a directory MyPackage
2. Copy MyClass.java to MyPackage
3. compile as javac MyPackage\MyClass.java
4. In order to make this class available set root directory of MyPackage in classpath. for eg if you created directory with c:\test\MyPackage and copied MyClass.java so that the path is
c:\test\MyPackage\MyClass.java then
set CLASSPATH=c:\test;%CLASSPATH%
javac c:\test\MyPackage\MyClass.java
Now you are ready to use MyClass.class ( But remember the class must be referred to as MyPackage.MyClass )
