Java Java File.isDirectory()

public boolean isDirectory()
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
