1) Main Class File: FileEncryptDecrypt.java

2) Result encrypted/decrypted file’s will be available in your java application files directory it self.

3) In case of  ” Multiple Files ” , make sure you have to put all the source files into your java application running directory (or) put your java .class file’s into your source directory where the files are available.
