Delete a File
In this section, you will learn how a specified
file or directory is deleted. For deleting a file from a directory you need to give the file name
to be deleted.
Description of program:
The following code of program deletes a file from a directory.
In this program the compiler will ask to enter the name of the file to be
deleted. For this we have used "BufferedReader(new
InputStreamReader(System.in));" method as you very well know about it.
If the file exists in the directory then it will be deleted otherwise we will
get a message that "file was not successfully deleted".
import java.io.File;
import java.io.*;
public class DeletingFile {
public static void main(String args[])throws IOException{
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter the file name to delete:");
String file_name = in.readLine();
File file = new File("File already exist!");
boolean exist = file.createNewFile();
if (!exist){
System.out.println("File was successfully deleted.\n");
} else {
System.out.println("File was not successfully deleted.\n");
}
}
}
