    Thread searchTest = new Thread(() -> {
        while(true)  {
            performSearchTest();
            try {
                Thread.sleep(500);

Alternate, but Runnable does not name thread, currentThread().getName() == main.

```

Runnable searchTest2 = ()-> { while(true) { performSearchTest(); try { Thread.sleep(500); } catch (InterruptedException e) { throw new RuntimeException(e); } } }; searchTest2.run();
