The J2se|xml Properties class is no longer new, it has been in the early days of Java programming, and almost nothing has changed. The Tiger version of J2SE enhances this class, not only by specifying multiple key-value pairs separated by an equal sign in a single line, but also by loading and saving these key-value pairs in an XML file. In a series of tame Tiger articles, John Zukowski shows how to harness this new generation of "horse-riding". The

Class Concept: A class is a collection of objects that have the same properties and operations. It provides a uniform abstract description of all objects that belong to the class, including properties and operations in two main parts. In an object-oriented programming language, a class is a stand-alone program unit that should have a class name and consist of two main parts: a description of the property an

Properties Property associates a value with a specific class, struct, or enumeration. A store property stores a constant or variable as part of an instance, while a computed property evaluates (not stores) a value. Computed properties can be used for classes, structs, and enumerations, and stored properties are used only for classes and struct bodies.

In this paper, we analyze the static static properties of the PHP object-oriented system and the call to it. It is easy to understand how they are called (whether they can be invoked or how they are invoked), and they need to understand where they are stored in memory. Static properties, methods (both static and non-static) in memory, only one location (not static prope
