以下示例显示java.io.File.isDirectory()方法的用法。
package com.jc2182;
import java.io.File;
public class FileDemo {
public static void main(String[] args) {
File f = null;
String path;
boolean bool = false;
try {
// create new file
f = new File("c:");
// true if the file path is directory, else false
bool = f.isDirectory();
// get the path
path = f.getPath();
// prints
System.out.println(path+" is directory? "+ bool);
// create new file
f = new File("c:/test.txt");
// true if the file path is directory, else false
bool = f.isDirectory();
// get the path
path = f.getPath();
// prints
System.out.print(path+" is directory? "+bool);
} catch(Exception e) {
// if any error occurs
e.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
c: is directory? false
c:\test.txt is directory? false
