----- hands brains to find files in the specified folder specified size

 

 

Ideas: First, to get the file size and you want to get, and then determine whether to file, if the file is determined that its size is equal to the specified size, is output. If it is a folder, then you need a recursive algorithm to operate the sub-file, written before the recursive algorithm to traverse file

Code:

package com.testHomework;

import java.io.File;

public  class WalkFileTree {

    public static void main(String[] args) {
        File file = new File("D:/java文件");
        Search(file,1024*100);
    }
    // find the specified folder all the files of the specified size 
    public  static  void Search (File File, int size) {
         IF (file.isFile ()) {
             IF (file.length () == size) {
                System.out.println(file.getAbsolutePath());
            }
        }else if(file.isDirectory()) {
            File[] files = file.listFiles();
            for(File f:files) {
                Search(f,size);
            }
        }
    }
}
