Java 9에서는 실행 중인 프로세스의 ID를 어떻게 얻을 수 있나요?

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
CPU Duration: 0 seconds</strong>
