Code to write OutputStream into a file
提问by user2254173
I need to write some output into a file using Java. Currently my code is writing the OutputStream on system console. My concern is I have to write process.getOutputStream()output which returns an OutputStream instance.
我需要使用 Java 将一些输出写入文件。目前我的代码正在系统控制台上编写 OutputStream。我担心的是我必须编写process.getOutputStream()返回一个 OutputStream 实例的输出。
final PrintWriter writer = new PrintWriter(process.getOutputStream());
writer.println(200);
writer.close();

Try this:
试试这个：
PrintWriter writer = new PrintWriter(new File("path/to/output-file.txt"));
It's just a matter of switching the output of the PrintWriterto the target you wish to use, a file in this case.
只需将 的输出切换PrintWriter到您希望使用的目标，在本例中为文件。

BufferedWriter write = new BufferedWriter( new FileWriter( "output.txt"));
write.write("your data");

Your question makes no sense. A ProcessOutputStreamisn't a file. It is a stream that is read by the process. What the process does with the data you send it is its business, not yours.
你的问题没有意义。AProcessOutputStream不是文件。它是一个被进程读取的流。该流程如何处理您发送的数据是它的业务，而不是您的业务。
