How do Java anonymous inner classes apply to threads?

Anonymous inner classes simplify the creation of multi-threaded code without naming, allowing for instant definition and use of thread classes. The main advantage is to simplify the code, while the limitation is that it cannot be extended. Use when you need to quickly create one or two threads. Keep the code short. If more complex logic is required, a separate class file should be created.

Application of Java anonymous inner classes in multi-threading

Java anonymous inner classes can be created directly without naming inner class. It simplifies multithreaded code because thread classes can be defined and used on the fly.

Syntax of anonymous inner classes

new Thread() {
    @Override
    public void run() {
        // 线程逻辑
    }
};

Practical case: Create and start a thread

// 创建一个匿名内部类线程
Thread thread = new Thread() {
    @Override
    public void run() {
        System.out.println("这是一个新线程。");
    }
};

// 启动线程
thread.start();

Advantages: Simplify code

Anonymous inner classes can simplify the creation process of thread classes because it does not require the creation of separate class files. This makes it very useful when you need to quickly create a thread or two.

Limitations: Cannot be extended

Anonymous inner classes cannot extend other classes or implement interfaces, so when you need to create reusable or extensible thread classes, they are not best choice.

Best Practice: Keep it Short

Code in anonymous inner classes should be kept short as they can become difficult to maintain and debug. If more complex code is required, it's better to create separate class files.

Conclusion

Java anonymous inner classes provide an easy way for multi-threaded development. They can be very useful when threads need to be created and used quickly. However, for more complex or scalable scenarios, it is better to create separate class files.
