Thumbnailator is a thumbnail build library that is smoother for the Java interface. By simplifying the thumbnail process from the APIs that provide existing image files and image objects, two or three lines of code can generate thumbnails from existing pictures and allow fine-tuning of thumbnail builds while maintaining the minimum amount of code that needs to be written. It also supports batch generation o

So only this is the worst!!Before has been the android under the call so file with JNI, now try Java in the win platform to call the DLL first or the old routine, directly in the DLL popped a message box the concrete flow is as follows: Define a method in Java, implement this method in C + +, pop t

Recently, in order to increase the matching rate of queries, the CMS system needs to add pinyin search fields. On the internet, it found the java open-source class library of pinyin4j, which provides conversion of Chinese to Chinese pinyin (and supports polyphonic words, I looked at his demo and decided to use it. Because in actual use, I need to consider the different arrangement and combination of polypho

How is the decoration mode used by the java io library reflected?Overview There are about 85 classes in the I/O package of java, which is really complicated. Otherwise, these classes can be divided into the following four parts.Input stream output stream Byte stream InputStream OutputStream Stream Reader Writer In short, the corresponding four parts are neat, wit

Code reuse is a very important factor in software development, and it is a good idea to put common functions together and encapsulate them into a library. Whenever you need it, just call it. Creating a library like this is easy for Java to use. Here's a simple example of using Eclipse to create a math library with only

An experienced Java program person often defines a common statement as a tool and then puts it in its own ToolPak. Do not know if we have such a habit of operation, anyway, the author's tool library, there are hundreds of tools. With these tools, it is very convenient for the author to develop Java applications. That is, you can not worry about the conflict cause
