For example 0x10010x1000=0x1000, you can determine that the mask value of 0x1001 contains the mask value of 0x1000. This is how unity's 3 layers are represented.

RxJava development essentials 2-why is it Observables?Why is it Observables? In the object-oriented architecture, developers are committed to creating a group of decoupled entities. In this way, entities can be tested, reused, and maintained without interfering with the entire system. Designing such a system brings about a tricky negative impact: maintaining consistency between related objects. In the Smalltalk MVC Architecture, the first example of t

The human class can be found in Java from/home/vamei/javapackage, and the Testagain class can be found from.Alternatively, you can set the system's CLASSPATH environment variable to add the above path to the variable without typing the-classpath option each time. Package-like mechanisms are also common in other languages, such as the import mechanism in Python. They are all designed to better organize and use existing programs. Using the package, we can easily ex
