The first chapter Hello, lambda expression!
Section I.
Java's coding style is facing tremendous changes.
Our daily work will become simpler and more expressive. Java is a new way of programming that has been in other programming languages as early as a decade ago. Once these new features are introduced into Java, we
Many of the core Java face questions come from multithreaded (multi-threading) and collection frameworks (collections framework), which are required to understand the core threading concepts. This article collects some typical Java threading problems that are often asked by senior engineers.

Collection of Mixed Problems in Java
First, the difference between final, finally, and finalize.
Final? Modifier (keyword) If a class is declared as final, it means that it cannot generate a new subclass and cannot be inherited as a parent class. Therefore, a class cannot be declared both abstract and final. Declare variables or methods as final to ensure that they are not changed during use. Variables decl

Last PostI have discussed several misuse of Java exception mechanisms. Today we will talk about topics related to JVM (and Java compiler. Why about JVM pinch? Because many Java programmersLack of knowledge about JVM makes it impossible to get started when encountering certain technical problems. In addition, the lack o
How to solve Java/J2EE Chinese problems
Most programmers have encountered Java Chinese problems in programming, but as long as you understand the Chinese problem principle of the Java System, we can say goodbye to Chinese
typical negative examples, in this way, you can perceive and avoid these problems keenly in your actual work.
Counterexample: discard exception
Code: Lines 15-18.
This code captures exceptions without any processing. It can be regarded as a killer in Java programming. In terms of the frequency and severity of the problem, it may be comparable to that of the C/C

Artificial intelligence programs can be implemented in almost all programming languages. The most common ones are: Lisp, Prolog, C/C ++, and Java recently.
LISP
Advanced languages such as LISP are favored in artificial intelligence, because after years of research in colleges and universities, they chose quick prototypes instead of quick exe

Waste, learning programming language needs a relatively long period of time, can not skyrocketing rise, which requires a process, in the process of slowly accumulating experience, solid foundation. Do not think that you have written a simple small program, you think you have learned very well, thi
If the application system is oriented to multiple languages, you have to solve the internationalization problems during programming, including style issues on the operating interface, versions of prompt and help languages, and customization issues.

83.JAVA programming Ideas-about Java performanceThe Java language has a particular emphasis on accuracy, but reliable behavior is at the expense of performance. This feature is reflected in aspects such as automatic garbage collection, rigorous run-time checks, full bytecode checking, and conservative run-time synchron
Typical java problems: Pass the value or pass the reference-general Linux technology-Linux programming and kernel information. The following is a detailed description. Classic problems, but they are not easy to understand. Especially for java programmers with c-basics, they
The threading model of the Java programming language may be the weakest part of this language. It is completely unsuited to the requirements of the actual complex program and is not object oriented at all. This article recommends significant modifications and additions to the Java language to address these issues.The Java
