java实现的文件复制

public static void main(String[] args) { // TODO Auto-generated method stub Scanner sc = new Scanner(System.in); System.out.print("DOS: >"); String command = sc.nextLine(); //split()方法按照指定的分隔符拆分字符串为字符数组 String[] c = command.split(" "); String pathName = c[1]; String target_path = c[2]; FileUtil fileUtil = new FileUtil(); //读取文件 String data = fileUtil.doRead(pathName); data=data.substring(0, data.length()-1); //复制文件到目标路径 fileUtil.doWriter(data, target_path); }
