This source code shows you how to delete a file by using the File.delete( ) method in Java.

Method:

Class File

public boolean delete()

Deletes the file or directory denoted by this abstract pathname.

Example:

import java.io.*;

public class DeleteFiles {
    public static void main(String[  ] args) {
        if (args.length != 1) {
            System.err.println("Usage: java Delete ");
            System.exit(0);
        }
        try { delete(args[0]); }
        catch (IllegalArgumentException e) {
            System.err.println(e.getMessage( ));
        }
    }    
    public static void delete(String filename) {
        File f = new File(filename);
        if (!f.exists( )) fail("Delete: no such file or directory: " +filename);
        if (!f.canWrite( )) fail("Delete: write protected: " + filename);
        if (f.isDirectory( )) {
            String[  ] files = f.list( );
            if (files.length > 0)
                fail("Delete: directory not empty: " + filename);
        }
        boolean success = f.delete( );
        if (!success) fail("Delete: deletion failed");
    }
}
