字节数组流

public class IOTest10 {
    public static void main(String[] args) throws IOException {
        //将指定字符串存放到byte数组中
        byte[] bytes="Talk is cheap,show me the code".getBytes();//创建源

        InputStream is=null;//选择流
        is=new ByteArrayInputStream(bytes);
        byte[] bytes1=new byte[5];//每次读取5个字节
        int len=-1;
        while((len=is.read(bytes1))!=-1){
            String string=new String(bytes1,0,len);//转换成字符串
            System.out.println(string);
        }
    }
}

public class IOTest11 {
    public static void main(String[] args) {
        byte[] dest=null;//创建源
        ByteArrayOutputStream os=null;//选择流
        os=new ByteArrayOutputStream();//不需要参数

        String string="Talk is cheap,show me the code";
        byte[] bytes=string.getBytes();
        try {

            System.out.println(bytes.length+"-->"+new String(dest,0,os.size()));//dest.length()
