如何在Java中并发执行相同的方法

抱歉，如果这是一个非常基本/愚蠢的问题

我有一个方法，需要几分钟才能运行。我想在多个对象上同时运行此方法。我在想我该怎么做？甚至只是指向正确文档的指针。我不确定我是否应该使用线程，或者ExecuteService或者什么

下面是我想同时运行的方法。我想同时删除多个vm

private void deleteVm(String workspace, String vmName) {
    println("Delete VirtualMachine: " + vmName + " in Workspace " + workspace);
    Job job = executeDelete(getWorkbench().deleteVirtualMachine(sub(), workspace, vmName));
    println(job);

    subscribeToJobLogs(job);

    awaitUntilJobNotRunningOrNotFound(() -> executeCall(getWorkbench().getVirtualMachineDeleteJob(sub(), workspace, vmName)));
}

若要同时调用方法，则需要线程。并发性的Java文档：

您可以选择如何在java中创建/使用线程

(一) 如果您知道需要多少线程，您可以像下面这样手动创建线程：

Thread thread1 = new Thread(()->deleteVm("a","b");
Thread thread2 = new Thread(()->deleteVm("c","d");

//START the threads
thread1.start();
thread2.start();

CompletableFuture.runAsync(() -> deleteVm("a", "b"));
CompletableFuture.runAsync(() -> deleteVm("c", "d"));

(二) 您可以像这样使用默认线程池（通常是每个cpu核心的线程）：

Thread thread1 = new Thread(()->deleteVm("a","b");
Thread thread2 = new Thread(()->deleteVm("c","d");

//START the threads
thread1.start();
thread2.start();

CompletableFuture.runAsync(() -> deleteVm("a", "b"));
CompletableFuture.runAsync(() -> deleteVm("c", "d"));

(三) 您可以像这样创建自己的线程执行器

ScheduledExecutorService executorService = Executors.nScheduledExecutorService executorService = Executors.newFixedThreadPool(5)

executorService.submit(() -> deleteVm("a", "b"));
executorService.submit(() -> deleteVm("c", "d"));
