範例

在下面的程式碼顯示如何使用File.isDirectory()方法。

import java.io.File;

public class Main {
  public static void main(String[] args) {

    File f = new File("c:");

    boolean bool = f.isDirectory();

    String path = f.getPath();

    System.out.println(path + " is directory? " + bool);

    f = new File("c:/test.txt");

    bool = f.isDirectory();

    path = f.getPath();

    System.out.print(path + " is directory? " + bool);

  }
}

執行上面程式碼，得到以下結果 -

c: is directory? true
c:\test.txt is directory? false
