Java can cross the platform because Java virtual functions cross-platform.Since the code compiled by the Java program is not code that can be run directly by the hardware system, it is an "intermediate code"-bytecode. Different Java Virtual machines (JVMS) are then installed on different hardware platforms, which are then "translated" by the virtual machine (JVM) into code that the corresponding hardware platform can execute. So for Java programmers,

Both Android and iOS Development support C + + development and can be used in a set of code multi-platform. At the same time, C + + difficult to decompile the characteristics of the Android development can bring code confidentiality, and another native features can improve the efficiency of the operation of the code. First, why use C + + Easy to transplant, the use of C + + Write library can be easily used on other platforms.

Having previously been an Android, and recently developing an iphone client, the most troubling of all is the inconsistency between the Java, Android and iphone three platforms plus decryption . Because the end of the phone is usually the Java-developed web service,android and iphone clients invoke the same Web Service interface, for data security considerations, to encrypt the data. The headaches are coming, it's hard to write a set of encryption pro

The Tablespace feature-the ability to replicate data files directly between Oracle instances without unloading and loading data-was introduced in Oracle 8i and has since become a feature. Initially, the tablespace and destination databases to be transferred must have the same size module. Support for the increased number of module sizes in Oracle 9i overcomes this limitation. Now, in Oracle 10g, the limitations of the platform have also been largely resolved. The Recovery Manager (Recovery Manag

The Mule ESB solves the interaction problems among various systems, platforms, and complex systems, and supports a variety of transport protocols, such as JMS, FTP, JSON, XML, RMI, in addition to Web service support. the next one is about to invoke the JMS messaging service through the ESB so that each system can com

mobile devices, Over-believing that HTML5 is a problem. From the perspective of the programming language trend, the decrease in javascript and the increase in objectiveC prove that HTML5 is not suitable for mobile application development, No matter how GPU acceleration is used, HTML5 graphics rendering is still dependent on the CPU, which cannot meet the current demand for software smoothness.. Now it seems that Quora's combination of HTML flexibility and native UI of local applications ma

(1) 10gen is a cloud platf

, we have never fixed the issue, this is because Microsoft's VB + Asp has become a solution that everyone is familiar with after a long period of work. Java has become an important factor for us to fear because of its high environmental requirements and low execution efficiency. However, the cross-platform features of Java have increasingly become a concern, especially for many large and medium-sized enterprises. Their existing network systems are based on a variety of

Chapter II platforms supported by SIGNALRSIGNALR supports a variety of server and client configurations. In addition, each mode of transmission has its own configuration requirements and limitations, and if some kind of transmission is not supported by the system, SIGNALR gracefully fails over to other types of transmission. For detailed instructions, refer to the transfer method and negotiate conversion in the previous chapter.1 server-side requireme

of a macro name in the source program is replaced with its defined string, called a macro substitution.#undef指令取消一个已定义的宏#if #elif #else #endif (detailed)Cross-platform often uses code, which can be written inside or outside the function#if defined (WP8) ... #elif defined (ANDROID) ... #elif defined (IOS) ... #endifSo depending on the platform, the compiler will choose different code to compile, throw away the code of the other platform.So WP8 ANDROID IOS How are these predefined macros defined?

When the impquery clause outputs data in the difference between unix and windows platforms, it is occasionally required to import only part of the data in a large table. In this case, the query clause may involve numeric, string, or date types in the query clause. to do this, perform a simple test to create tables and data :... when the imp query clause outputs data in the difference exp between unix and windows p
