不是哦，runnable现在是functional interface就是一个函数的接口罢了可以用在lambda上然后线程是接受runnable对象作为参数的所以最终还是要通过thread类来启动线程不是，Java中开启线程唯一的方法就是创建Thread的对象。不知道为什么总有很多面试题会问 “开启线程的两种方式，Thread 和 Runnable

我们先来看一下Callable接口的语法: packagejava.util.concurrent;/*** A task that returns a result and may throw an exception. * Implementors define a single method with no arguments called * {@codecall}. * * The {@codeCallable} interface is similar to {@link* java.lang.Runnable}, in th...
Whether you're building a high-performance application or just trying to ensure smooth user interactions, understanding how to leverage threads is crucial. In this blog, you’ll learnwhat is runnable interface in Javaand how it can help you create faster, more responsive applications. Dive in!
基于Runnable接口实现多线程虽然可以通过Thread类的继承来实现多线程的定义,但是在Java程序里面对于继承永远是存在单继承局限的,所以在Java里面又提供有第二种多线程的主体定义结构形式,实现java.lang.Runnable接口,此接口定义如下:public InterfaceRunnable{ public void run(); }范例:通过Runnable实现多线程的 ...

Runnable接口仅要求实现一个方法,即`public void run()`。Java中接口方法默认是`public abstract`的,因此在实现时必须显式添加`public`修饰符。 **逐项分析**: - **A. void run()**:缺少`public`,访问权限低于接口定义,无法通过编译。 - **B. public void run()**:符合接口定义,正确。 - **C. publi...

The other way to create a thread is to declare a class that implements the Runnable interface. That class then implements the run method. An instance of the class can then be allocated, passed as an argument when creating Thread, and started. The same example in this other style looks like...
