学步园

   刚开始学习Java,一直想学但总是坚持不下来,回到家就想着玩游戏,看来是要下决心了,2010年要好好学习Java了.

   这是在网上看到的两个小例子,自己也做了一遍.

    1.

    try<br /> {<br /> FileInputStream in=new FileInputStream("C:/1.txt");<br /> FileOutputStream out=new FileOutputStream("C:/2.txt");<br /> byte[] by=new byte[1024];<br /> do {<br /> in.read(by, 0, 1024);<br /> out.write(by);<br /> } while (in.available()>0);<br /> in.close();<br /> out.close();<br /> }catch(ArrayIndexOutOfBoundsException e)<br /> {<br /> e.printStackTrace();<br /> }catch(IOException e)<br /> {<br /> e.printStackTrace();<br /> }

   2.

try {<br /> FileInputStream in=new FileInputStream("C:/1.txt");<br /> FileOutputStream out= new FileOutputStream("C:/2.txt");<br /> BufferedInputStream bufferedIn=new BufferedInputStream(in);<br /> BufferedOutputStream bufferedOut=new BufferedOutputStream(out);<br /> byte[] by=new byte[1];<br /> while (bufferedIn.read(by)!=-1) {<br /> bufferedOut.write(by);<br /> }<br /> //将缓冲区中的数据全部写出<br /> bufferedOut.flush();<br /> bufferedIn.close();<br /> bufferedOut.close();</p> <p> } catch (ArrayIndexOutOfBoundsException e) {<br /> // TODO: handle exception<br /> e.printStackTrace();<br /> }catch (IOException e) {<br /> // TODO: handle exception<br /> e.printStackTrace();<br /> }
