java 复制
利用java io实现文件复制 public class FileCopy { public boolean copyFile (String srcPath, String desPath) throws FileNotFoundException{ File srcFile,desFile; srcFile=new File (srcPath); desFile=new File (desPath); FileInputStream fis=null; FileOutputStream fos=null; byte[] buf=new byte[8*1024]; int nbyte; try { desFile.createNewFile(); fis=new FileInputStream (srcFile); fos=new FileOutputStream (desFile); while((nbyte=fis.read(buf))!=-1){ fos.write(buf, 0, nbyte); } fos.flush(); fos.close(); fis.close(); } catch (IOException e) { e.printStackTrace(); return false; } return true; } public static void main(String[] args) { String src = args[0]; String des = args[1]; FileCopy fc=new FileCopy(); try { if(fc.copyFile(src,des)) System.out.println("文件复制成功!"); else System.out.println("文件复制失败!"); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
