Runnable task5 = new Runnable() { public void run() { try { System.out.println("采集 start"); runCase(suite + "datacollection/Test-Dg-All-TestSuite.xml"); Thread.sleep(1000); System.out.println("task5 end"); } catch (InterruptedException e) { System.out.println("task5 interrupted: " + e); } } };优化一下这段代码

可以使用 lambda 表达式来简化这段代码，如下所示：

Runnable task5 = () -> {
    try {
        System.out.println("采集 start");
        runCase(suite + "datacollection/Test-Dg-All-TestSuite.xml");
        Thread.sleep(1000);
        System.out.println("task5 end");
    } catch (InterruptedException e) {
        System.out.println("task5 interrupted: " + e);
    }
};

使用 lambda 表达式可以使代码更加简洁易读，同时还可以减少冗余的代码。
