JavaAPI(9) - Java IO(File Test(2))

지난 File Test에 이어서 path와 file에 대해 이것저것 Check해보는 메소드들을 사용해보았습니다.

public class MyFileTest {
    public static void main(String[] args) {
        MyFileTest fileTest = new MyFileTest();

        String path = "C:\\";
//        String path = "C:\\sirius.txt";
        fileTest.checkPath(path);

        String fileName = "jinwoo.txt";
        fileTest.checkFile(path, fileName);
        fileTest.checkList(path);
    }

    public void checkPath(String path) {
        File file = new File(path);
        System.out.println(path + "is exists?" + file.exists());

        System.out.println("Make " + path + " Result => " + file.mkdir());
        System.out.println(path + "is Directory? => " + file.isDirectory());
        System.out.println(path + "is File? => " + file.isFile());
        System.out.println(path + "is hidden? => " + file.isHidden());

        System.out.println(path + "can Read? => " + file.canRead());
        System.out.println(path + "can Write? => " + file.canWrite());
        System.out.println(path + "can Execute? => " + file.canExecute());

        System.out.println(path + " last modified => " + file.lastModified());
        System.out.println(path + " last modified => " + new Date(file.lastModified()));
        System.out.println("Delete " + path + " result => " + file.delete());
    }

    public void checkFile(String path, String fileName) {
        File file = new File(path, fileName);
        try {
            System.out.println("Create Result => " + file.createNewFile());
            System.out.println("Absolute Path => " + file.getAbsolutePath());
            System.out.println("Absolute File => " + file.getAbsoluteFile());
            System.out.println("Canonical Path => " + file.getCanonicalPath());
            System.out.println("Canonical File => " + file.getCanonicalFile());

            System.out.println("Name => " + file.getName());
            System.out.println("Path => " + file.getPath());
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }
}

참고로, C 디렉토리는 권한이 필요하기 때문에 Make Result와 Delete는 false가 되었습니다. 

(코드 내부에서 Delete는 조심해서 사용하시기 바랍니다. FileName을 중요한 파일로 테스트하시면 날릴수도 있습니다.)
