bloated, as long as the methods in the interface appear, no matter whether they are useful to the classes dependent on it, these methods must be implemented in the implementation class, which is obviously not a good design. If you change this design to conform to the interface isolation principle, you must split interface I. Here we split the original interface I into three interfaces. The design 2 after the split is shown as follows: (Figure 2 Design following the interface isolation p

There are two ways to implement multithreaded code in Java, one is to inherit the thread class , and the other is to implement the Runnable interface .First, inherit the Thread classThe thread class is defined in the Java.lang package, and a class is referred to as a multithreaded operation class as long as it inherits the thread class.In the thread subclass, you must explicitly overwrite the run () method in the thread class, which is the principalExample: Inheriting the thread class for multit

How browser Event loops workThe browser has an event loop that checks the event queue, handles deferred events, UI events (such as clicks, scrolling, and so on), Ajax callbacks, and callbacks provided to settimeout () and SetInterval (), which are sequentially processed by the event loop.Therefore, when the settimeout () function is called, the provided callback is queued even if the delay is set to 0The callback stays in the queue until the specified time runs out, and the engine starts to exec
