DataInputStream 和 OutputStream 写入/读取长度的字符串

Question

如何读取Stringwith DataInputStream，与此代码一起存储：

DataOutputStream dataOut = new DataOutputStream (out); // Some other stream
String title = processed.getTitle();
dataOut.writeInt(title.length());
dataOut.writeBytes(title);

Answer 1

你可以这样阅读。

DataInputStream dataIn = new DataInputStream (input);
int length = dataIn.readInt();
byte[] array = new byte[length];
dataIn.read(array);
