即使不创建Runner对象，我也可以从线程的run方法访问Runner类中的process方法吗？

class Runner {
  public void process() {
    // some multithreaded code
  }
}

main() {
Thread t1 = new Thread(new Runnable() {
                public void run() {
                    process();
                }
           });
t1.start();
}

最佳答案

您可以将其设置为static：

class Runner {
      public static void process() {
        // some multithreaded code
      }
    }

然后：

public static void main() {
    Thread t1 = new Thread(new Runnable() {
                public void run() {
                    Runner.process();
                }
           });
    t1.start();
}

但是，如果没有process()限定条件或没有实例化，将无法引用Runner.方法。这是因为Java是Object Oriented语言。
