Introduction Java's heap is a run-time data area in which instances (objects) of the class allocate space. The Java Virtual machine (JVM) heap stores all objects that are established by the running application, which are established through directives such as new, NewArray, Anewarray, and Multianewarray, but they do not require program code to be released explicitly. In general, the heap is responsible for

assembler. The interface is defined by C and is written by the assembly. The advantage of this is that the execution is efficient, and it greatly facilitates the upper-level invocation.4. Say the library function (i.e. API). Library functions can be broadly divided into two categories, one is provided with the OS, and the other is third-party. With the library f

Recently, the company has a game product, the font has problems, I hope the automatic simple and complex screen automatic conversion behavior, reduce workload.So I use some of the Windows own conversion functions, but found that a large number of words are abnormal, can not be converted (test Iconv also found that cannot be converted).Taking this record some OPENCC libraries use the tutorial, which calls the OPENCC

Svn (subversion) is a version management tool that has emerged in recent years and is the successor of cvs. Currently, most open-source software uses svn as the code version management software, and the continuous code building platform needs to pull code from svn. Therefore
