JavaME(KJava ) 中原始IO流的读取

try {

//将原始的字节流转换为 【字符流】

InputStreamReader isr = new InputStreamReader(Test.class.getResourceAsStream("/t.xml"), "utf8");

InputStream is = Test.class.getResourceAsStream("/t.xml");

//ByteArrayOutputStream baos = new ByteArrayOutputStream();

//baos.toByteArray(); //将流转换成字节数组

StringBuffer sb = new StringBuffer();

//缓冲区

char[] buffer = new char[10];

int len = 0; //每次读取的长度

for (; (len =isr.read(buffer)) != -1; ) {

sb.append(buffer, 0, len);

}

/*while (isr.ready()) {

len = isr.read(buffer);

System.out.println("已读:" + len);

System.out.println("data:" + new String(buffer));

sb.append(buffer, 0, len);

}*/

System.out.println("completed:" + sb);

/****************************  输出流  *******************************/

byte[] data = new byte[1024];

ByteArrayInputStream bis = new ByteArrayInputStream(data); InputStreamReader isr = new InputStreamReader(bis);

e.printStackTrace();

}

}

InputStream   //字节流

Reader       //字符流

InputStreamReader  //字节流 -->> 字符流的转换(装饰)

ByteArrayOutputStream  //

ByteArrayInputStream //字节数组到流之间的转换
