Htop showing multiple java processes with different pids
提问by b.buchhold
Htop on my linux machine shows many "processes" after launching one java program/JVM. I do understand that the JVM runs multiple threads (for the actual program, for garbage collection, etc).
启动一个 Java 程序/JVM 后，我的 linux 机器上的 Htop 显示许多“进程”。我确实理解 JVM 运行多个线程（对于实际程序、垃圾收集等）。
But how come htop lists them as multiple processes with different pids. What exactly are those processes?
但是 htop 如何将它们列为具有不同 pid 的多个进程。这些过程究竟是什么？

Actually, it's just that htop by default shows each thread as a separate process. You can add the line hide_userland_threads=1to your ~/.config/htop/htoprcfile to show only one line.
实际上，只是默认情况下 htop 将每个线程显示为一个单独的进程。您可以将该行添加hide_userland_threads=1到~/.config/htop/htoprc文件中以仅显示一行。
