Java中while语句中如何使用read（）方法

while的括号中调用read方法，读一个字符存入b中，按回车键结束。括号中该如何填写？

Answer 1

File file = new File(fileName);
InputStream in = null;

byte[] b= new byte[1024];

try {
in = new FileInputStream(file);
int tempbyte;
while ((tempbyte = in.read(b,0,b.length)) != -1) {
String str = new String(bytes,0,n,"GBK"); // 转换成字符串
System.out.println(str); //打印出来
out.write(b, 0, n); //写入相关文件 }
in.close();
} catch (IOException e) {
e.printStackTrace();
return;
}
