In Java 9, how can we get the ID of a running process?

Java 9 has improved the Process API to obtain the PID## of a running process #, Get the child processes and/or descendant processes of a process, and also add a new help to list all running processes , get about Information about any process and classes for traversing the process tree. The information returned by these methods can be a snapshot of the processes running on the operating system.

pid() method of ProcessHandle to get the ID of the running process.

public class ProcessHandleTest {
   public static void main(String args[]) {
      <strong>ProcessHandle </strong>processHandle = <strong>ProcessHandle.current()</strong>;
      System.out.println("PID of running Process: " + <strong>processHandle</strong>.<strong>pid()</strong>);
      System.out.println("Command: " + <strong>processHandle.info()</strong>.<strong>command()</strong>.orElse("N/A"));
      System.out.println("CPU Duration: " + <strong>processHandle.info()</strong>.<strong>totalCpuDuration().get().getSeconds()</strong> + " seconds");
   }
}

<strong>PID of the running Process: 4248
Command: C:\Program Files\Java\jdk-9.0.4\bin\java.exe
