To allow the program to respond to user operations as soon as possible, the thread is often used when developing Windows applications. If a thread is not used for time-consuming operations, the UI interface will be stuck for a long time. In this

18. Good interfaces are easy to use correctly and cannot be misused. You should try to achieve these properties in all your interfaces. "Promoting correct use" includes interface consistency and compatibility with built-in behaviors. The methods to

Exceptions in Java involve the problem of parent-child classes, which can be summed up in a sentence: The exception that is thrown by the constructor of a subclass must contain the exception of the parent class, and the method of the subclass can

In the Friday and the weekend, work to sneak in, looking at the Java cocurrent also by the way the Thread.Interrupt and Java 5 after the implementation of the Locksupport. Before introducing, let's throw a few questions. The relationship between

The usual practice in lieu of try/catch/throw is to return a return code (sometimes called an error code), such as printf (), scanf (), and malloc (), which is how the caller tests the return value to determine whether the function was successful.

 promise is a very simple concept, and even if you don't have a chance to use it, chances are that you've learned about it. Promise is a valuable constructor that can help you avoid using nested anonymous methods and assemble asynchronous code in a

In the early stages of Java programming, a professor at the State University of New York (SUNY) in Oswego decided to create a simple library to help developers build applications that would better handle multi-threaded situations. This is not to say

Observer mode is common in Swing development, and is useful for eliminating the coupling of components in scenarios other than GUI applications. However, there are still some common flaws in the registration and invocation of listeners. In this
