Is it possible to format a memory stick, pen drive or disk using Java? [closed]

Answer 1

It is very system specific, there is no universal way to perform this. Your options are

1. Create a JNI library to perform this using system calls
2. Write a wrapper class around utilities that perform this operation (for example, capture stdout and give inputs to stdin for an external process)
3. Use OS-specific techniques (as previously mentioned) to zero out devices
4. Use something like fat32-lib to manipulate specific file system types.
