[英]perform same operation as linux pipe in java?
How can I do the following in Java code (without invoking the shell directly - not using the pipe operator at all)? 如何在Java代码中执行以下操作(无需直接调用外壳程序-完全不使用管道运算符)?
echo path | ./app
Is this the same as starting the app and then writing to STDIN? 这与启动应用程序然后写入STDIN一样吗?
I want to be able to start a process from Java and destroy it (and not worry about child processes) 我希望能够从Java启动一个进程并销毁它(而不必担心子进程)
您可以使用ProcessBuilder
,它包装Process
类以从Java应用程序启动进程,并使用Process#getInputStream
和Process#getOutputStream
捕获其IO流。
