Returns:
true if the file was deleted by this method; false if the file could not be deleted because it did not exist

package com.logicbig.example.files;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;

public class DeleteIfExistsExample {

    public static void main(String... args) throws IOException {
        Path path = Files.createTempFile("test-file", ".txt");
        //deleting
        boolean deleted = Files.deleteIfExists(path);
        System.out.println("File deleted: " + deleted);
        //deleting non-exiting file
        boolean deletedAgain = Files.deleteIfExists(path);
        System.out.println("File deleted again: " + deletedAgain);
    }
}
