How to Copy a File from One Location to Another in Java?

Condition for Copying a File from One Location to Another in Java

Description: Copying a file from one location to another in Java involves using classes like `FileInputStream` and `FileOutputStream` or utilizing the `Files` class from the `java.nio.file` package. With `FileInputStream`, the file is read byte by byte, and with `FileOutputStream`, the data is written to the destination file. Alternatively, `Files.copy()` from `java.nio.file.Files` provides a simpler and more efficient way to copy files, allowing for options such as replacing the destination file or copying attributes. The `InputStream` and `OutputStream` approach requires handling resources carefully using try-with-resources to ensure the streams are closed after the operation. Error handling is essential to catch exceptions such as file not found or access issues, and it is important to ensure that the target directory exists before performing the copy operation.
