Javaでファイルかどうかを判断する方法

package com.test; 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 a file, else false bool = f.isFile(); // get the path path = f.getPath(); // prints System.out.println(path+" is file? "+ bool); // create new file f = new File("c:/test.txt"); // true if the file path is a file, else false bool = f.isFile(); // get the path path = f.getPath(); // prints System.out.print(path+" is file? "+bool); }catch(Exception e){ // if any error occurs e.printStackTrace(); } } }

c: is file? false c:est.txt is file? true
