Using brush to make abstract ink portrait effect This tutorial mainly introduces the magical uses of ink brush. Seemingly some simple brushes, if properly used, can also make some very artistic pictures of the effect. Before making, it is best to collect some brush material such as splash or ink.Final effect1, create a new 700*1000 canvas, and then create a new layer, fill white, add gradient overlay to the layer, the color is #778989, #cbcfce. Angle is-61 degrees. Parameters such as figure. 2

In enterprise development, EJB needs scalable performance and transaction, security mechanism, so as to ensure the smooth development of enterprise system, rather than develop to a scale to replace a set of software system. EJB on the basis of JavaBean also made a number of requirements, more complex. Just understand it, we can't use it. Pojo Full name Plain ordinary Javaobject, simple Java ob

Wireframes or models can be connected using Invision or Uxpin applications to create prototypes that can actually be clicked. As shown in the figure above, there are various dimensions of fidelity and workflow.

A few words to understand POJO, JavaBean, EJB, DAO, DTO, VO, PO, BO, do 1. POJO POJO (Plain old Java Object) is called by Martin Fowler, Rebecca Parsons and Josh Mackenzie in a speech in 2000. According to Martin Fowler, "Plain old Java object" is literally translated as "pure old-fashioned Java objects," but everyone uses "simple Java objects" to address it. The implication is that there are some private parameters that act as properties of the o

the third and fourth ways. Sixth (enum): public enum Singleton { INSTANCE; public void Whatevermethod () { } } This is the way effective Java author Josh Bloch advocates, not only to avoid multi-threaded synchronization problems, but also to prevent deserialization from recreating new objects, which is a very strong barrier, but Personally think that because of the 1.5 to join the characteristics of the enum, write in this way

initialize the instance, which differs from the third and fourth way (a very subtle difference): The third and fourth Way is if the singleton class is loaded, Then the instance will be instantiated (not reaching the lazy loading effect), and this way is that the singleton class is loaded and instance is not necessarily initialized. Because the Singletonholder class is not actively used, the load Singletonholder class is displayed only when the GetInstance method is called, thus instantiating th

in the map correspond to one by one, and a key is the corresponding value. But sometimes we need to reverse query, such as a value to find its key, this data structure is called bidirectional map, unfortunately, the JDK does not support it.Apache and guava together provide this bidirectional map implementation, which stipulates that both the key and the value must be 1:1 relationships. 7. Copy of MapJava provides many ways to replicate a map, but those methods do not always synchronize. Simply

synchronization problem with this notation. This approach is advocated by effective Java author Josh Bloch, not only to avoid multithreading synchronization problems, but also to prevent deserialization of new objects from being recreated. Personally believe that because of the 1.5 only to join the enum characteristics, the penetration rate is not high enough, in practice, found that the use of is not very extensive. The author's evaluation of this m

a concurrent application can cause sporadic failures that often occur until deployment (when the application is exposed for loading). and encapsulating additional locks around a class that is already thread-safe can affect performance and even cause deadlocks. Josh Bloch provides useful taxonomies in his effective Java programming Language Guide (see Resources) for a class's thread-safety level documentation. Classes can be grouped into one of the fo
