一，框架概念

二，Commons-io框架

 

三，使用案例

 

package BigDecimal;

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;

public class Main12 {
    public static void main(String[] args) throws IOException {
        //复制文本文档
        FileUtils.copyFile(new File("C:\\untitled1\\untitled\\src\\BigDecimal\\Duxiaonan"),new File("C:\\untitled1\\untitled\\src\\BigDecimal\\Duxiaonanf11111"));
        //复制文件夹
        FileUtils.copyDirectory(new File("C:\\Users\\du'xiao'nan\\Videos\\bilibili\\1328884159"),new File("C:\\Users\\du'xiao'nan\\Videos\\bilibili\\123456789"));
        //删除
        FileUtils.deleteDirectory(new File("C:\\Users\\du'xiao'nan\\Videos\\bilibili\\123456789"));
    }
}
