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。
