Java文件比较

Java文件夹遍历：

 

package com.xiva.demo.file;

import java.io.File;
import java.util.HashSet;
import java.util.Set;


public class FileDemo {

    
    private Set<String> directorySet = new HashSet<String>();
    
    public void traversingDirectory(String filePath)
    {
        File file = new File(filePath);
        if(file.isDirectory()){
            directorySet.add(file.getAbsolutePath());
            File[] fileArray = file.listFiles();
            for (File subFile:fileArray) {
                traversingDirectory(subFile.getAbsolutePath());
            }
        }
    }
    
    
    public static void main(String[] args)
    {
        FileDemo demo = new FileDemo();
        demo.traversingDirectory("F:\\WorkSpace\\EclipseProjects\\MyJavaProject");
    }
}

 本次程序的目的是比较两个文件夹以及文件，然后进行Copy；test
