根据process进程id判断进程是否存在，Java

List<Long> pids = new ArrayList<>();
        ProcessHandle.allProcesses()
                .limit(1000)
                .forEach(new Consumer<ProcessHandle>() 
                    @Override
                    public void accept(ProcessHandle processHandle) 
                        pids.add(processHandle.pid());
                    
                );

        boolean alive = false;
        for (long l : pids) 
            if (l == pid) 
                alive = true;
                break;
