In a multithreaded Java program, does each thread have its own copy of System.out?

由 孤街浪徒 提交于 2019-12-17 16:34:03
问题 I'm writing a multithreaded Java program where each thread potentially needs its standard output redirected to a separate file. Each thread would have its own file. Is it possible to redirect System.out on a "per-thread" basis or are changes to System.out global across all threads? 回答1: Is it possible to redirect System.out on a "per-thread" basis No it is not possible. System.out is static and there is one per JVM that is loaded as part of the system classloader when the JVM initially boots.

Connecting an input stream to an outputstream

由 旧街凉风 提交于 2019-12-17 02:44:08
问题 update in java9: https://docs.oracle.com/javase/9/docs/api/java/io/InputStream.html#transferTo-java.io.OutputStream- I saw some similar, but not-quite-what-i-need threads. I have a server, which will basically take input from a client, client A, and forward it, byte for byte, to another client, client B. I'd like to connect my inputstream of client A with my output stream of client B. Is that possible? What are ways to do that? Also, these clients are sending each other messages, which are

Proper way to close an AutoCloseable

由 巧了我就是萌 提交于 2019-12-17 02:32:14
问题 What is the most reliable pattern to follow when closing an OutputStream, ServerSocket, or other object that implements the AutoCloseable interface? Should I use try - catch - finally ? Or a shutdown hook. 回答1: The correct way to use an AutoCloseable instance is with a try-with-resources block, so the resource is reliably closed even if an exception is thrown. Like this: try (OutputStream stream = new ...) { ... // use the resource } catch (IOException e) { ... // exception handling code }

问题 I want to write data to file when it's opened, but it doesn't work. Calendar getTime works nice, System.out.println() proves this. Please, any idea, what's wrong...? Main class: public static void main(String[] args) throws IOException { // TODO code application logic here CurrentTime ct = new CurrentTime(); } CurrentTime class: public class CurrentTime { public OutputStream output; public InputStream input; public Process npp; CurrentTime() throws IOException { Timer t = new Timer(); npp =

问题 What will happen if I create two instances of class FileInputStream and FileOutputStream using the default constructor and as an argument specify the same path and file name like this.. FileInputStream is = new FileInputStream("SomePath/file.txt"); FileOutputStream os = new FileOutputStream("SamePath/file.txt"); Let's imagine that we have a few strings inside the file "file.txt". Next, using a loop I am trying to read bytes from the file.txt and write them into the same file.txt each
