often only the outer class calls this inner class. Therefore, it is not necessary to use a Java file specifically to store this class.B, Static is used to modify the internal members of the class. such as static methods, static member variables. Its only function is to be generated as the class is loaded (not as the object is produced), so that it can be obtained directly with the class name + static member name. This allows the static inner class to be understood, and it can be obtained direct

many places. Anticipatory, deadline, and cfq I/O scheduling both use the RB tree for request tracking, as well as the CD/DVD drive package management. The high-resolutiontimer uses the RB tree to organize scheduled requests. The ext3 file system also uses the RB tree to manage directories. The Virtual Storage Management System also provides a Rb tree for VMAs (virtual memory areas) management. Of course, network data packets scheduled by file descriptors, password keys, and "Level Token buckets
