java复制图片实现方法

原图片路径：srcpic

目的图片路径：despic

 public static void copyPic(String srcpic, String despic){
         File file1=new File(srcpic);
         File file2=new File(despic);
         byte[] b=new byte[(int)file1.length()];
         FileInputStream in=null;
         FileOutputStream out=null;
         try {
           in=new FileInputStream(file1);
               //没有指定文件则会创建
           out=new FileOutputStream(file2);
               //read()--int，-1表示读取完毕
           while(in.read(b)!=-1){
             out.write(b);
           }
           out.flush();
           in.close();
           out.close();
         } catch (Exception e) {
           e.printStackTrace();
         }
     }

亲测好使。
