CLSID list (Windows Class Identifiers) Certain special folders within the operating system are identified by unique strings. Some of these strings can be used with fileselectfile, fileselectfolder, and run. For example: Fileselectfile, outputvar, ,:{ 645ff040-5081-101b-9f08-00aa002f954e}; select a file in the recycle bin. Fileselectfolder, outputvar,: {20d04fe0-3aea-1069-a2d8-08002b30309d}; select a folder within my computer. CLSID Meani

The names of packages, classes, methods, parameters, and variables in Java consist of any order of size letters, numbers, underscores (_), and dollar signs ($)identifier : cannot start with a number and cannot be a reserved keyword in Javasuch as: Yourname, Yourname_dxh, Li_yourname, $yourname are legal identifiersClass, 67.9,hello World is not legal, class is the keyword, 67.9 starts with a number, there is a space in the middle of Hello worldHttp://www.cnblogs.com/liunanjava/p/4234790.htmlJava

In the Java language, names for various variables, methods, and classes are called identifiersNaming rules for Java identifiers:Should start with a letter, underscore, dollar symbolfollowed by letters, underscores, dollar breaks, or numbersJava identifier case sensitive, unlimited lengthNote: You cannot use keywords in Java to make identifiers.Java reserved KeywordsThe Java language has 51 keywords, where const and goto are reserved but not used. You cannot use reserved keywords to name a class,

Data segments and stacks are independent of each other. Since Glob is stored in the initialization data segment, x is stored in the stack, and the child process changes it without affecting the parent process.Two common ways to use fork: The parent process copies itself so that the parent and child processes run different
