java – 直接调用run方法是不好的做法

如果不是一个好主意,最好将代码放在另一个可以被新线程调用或复制代码的方法中吗？

这是一些示例代码,它只是为了说明我想要实现的目标：

class Main {
    public Main() {
        new Thread(new WorkerThread(1,2)).start(); // This is what I'd do if I wanted it to run in a new thread.
        new WorkerThread(1,2).run(); // Is it bad practice to do this?
    }
}

class WorkerThread implements Runnable {
    private int int1,int2;

    public WorkerThread(int int1,int int2) {
        this.int1 = int1;
        this.int2 = int2;
    }

    public void run() {
        // Do something time consuming with the ints.
    }
}
