Delete file on JVM exit
This is an example of how to delete a File on a JVM exit. We are using the File class that is an abstract representation of file and directory pathnames. Deleting a File on a JVM exit implies that you should:
- Create a new File instance by converting the given pathname string into an abstract pathname.
- Use
deleteOnExit()
API method of File. This method requests that the file or directory denoted by this abstract pathname be deleted when the virtual machine terminates. Files (or directories) are deleted in the reverse order that they are registered. Invoking this method to delete a file or directory that is already registered for deletion has no effect. Deletion will be attempted only for normal termination of the virtual machine, as defined by the Java Language Specification.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core; import java.io.File; public class DeleteFileOnJVMExit { public static void main(String[] args) { File file = new File("C://delete_file.txt"); // Requests that the file or directory denoted by this abstract // pathname be deleted when the virtual machine terminates. file.deleteOnExit(); } }
This was an example of how to delete a File on a JVM exit in Java.
