clojure javafx

The design of the Java language has been purposefully cut to avoid some problems that have been discovered in the previous generation of products. For example, the designers of the Java language feel that multiple inheritance in C + + poses too much complexity, so they choose not to include the attribute. In fact, they rarely build extensibility options in the language, relying only on single inheritance and interfaces. Other languages, including the Java Next generation language, have great po

The core role of microBecause the micro receive parameters can be very complex, and do not evaluate, so you can receive list, in the internal conversion, after processing execution, you can also receive a completely non-Lisp syntax, internally converted to Clojure can execute the list.This allows you to create your own DSL and implement the Clojure macro as a DSL parser.The difference between micro and func

Clojure provides several powerful data structures (collections)I. Types of collections1. VectorEquivalent to an array such as: [2 3 5], ["Ad" "Adas" "Adadsads"]2. ListEquivalent to a linked list, such as: ' (2 3 5), ' ("Ad" "Adas" "Adadsads")Compared to vectors, [] becomes (), and because () the symbol is used for function calls, in order to differentiate, it needs to be preceded by a single quotation mark '3. MapSyntax format such as: {: a 1:b 1}Map

Clojure provides an operation form other than functions and macros. Special form is a limited number and is not implemented by clojure itself. It mainly includes the following: Catch, def, do, dot ('.'), finally, FN, if, let, loop, Monitor-enter, monitor-exit, new, quote, recur, set !, Throw, try, and var. Complete documentation see: http://clojure.org/special_forms Vars should be explained here. First,

Of course, a complete web app needs to write logs. Here I use slf4j + logback. First, add two dependencies to the project. CLJ file in the my-website directory: Tools.

Http://stackoverflow.com/questions/1314732/scala-vs-groovy-vs-clojureGroovy is a dynamically typed language, whose syntax are very close to Java, with a number of syntax improvements that Allo W for lighter code and less boilerplate.

Now let's take a look atCode: The first one is nil, which has the same null value as Java. Like false, nil can express the condition that the condition is not true. The following is an explanation: Nilnil is a possible value of any data type in clojure. nil has the same value as Java null. the clojure conditional System is based around nil and false, with nil and false representing the values of logi

On the weekend, I suddenly thought that a physical engine is needed in the game engine. So I studied jbox2d (why jbox2d is better because I think jbox2d is more portable, whether other physical engines are used ). As I developed the javafx game engine wjfxgame, the example of the physical engine in it is not easy to learn. So I wrote another one. In fact, it is very simple. The Physical Operations of jbox2d are separated from the graphic rendering. We

The javafx beta version was released in. In fact, I saw it on the official website a few days ago, but it was busy that day and I didn't have time to write a blog. So it was not until today that I thought about writing. I always thought that javafx was not updated for a long time and thought it was Oracle giving up. Now it seems a big difference. So what are the improvements of

Software development is now a very hot occupation. From 2014 to 2024, demand for developers in the U.S. job market will grow by 17%, compared with a 7% increase in the average demand for all occupations, according to a statistical data released by the U.S. Labor Bureau. Many young people will choose programming as a starting point for their careers. How to learn programming well? How to become a good programmer?
