Ajax works by specifying that the location of a page can load all the output from another page, thus enabling a static page to retrieve the returned data information in the database. So Ajax technology enables a static Web page to communicate with the server without refreshing the entire page, reducing user latency while reducing network traffic and enhancing the friendliness of the customer experience.The core technology of

. Head and Stack Java's memory is divided into two categories, one is stack memory, and the other is heap memory. Stack memory refers to the method when the program enters the method, a separate private storage space is allocated for this approach, which is used to store local variables inside the method. When this method ends, the stack allocated to the method is released, and the variables inside the stack are freed. Heap-to-stack memory, typically used to hold data that is not placed in the c

different from traditional programs, and Sun is introducing Java as an open technology. Tens of thousands of Java development companies around the world are required to design Java software that must be compatible with each other. "The Java language relies on the power of the community rather than the power of the company" is one of Sun's slogan, and has been recognized by the vast number of software developers. This is completely different from the focus on the elite and the closed model advoc

encapsulation./*Final keyword:1,final is a modifier that can be used to modify classes, methods, and variables.2,final-Modified classes cannot be inherited.3,final-Modified methods cannot be overridden.A variable modified by 4,final is a constant that can be assigned only once.Why use final modifier variables. Actually in the program if a data is fixed,So it is possible to use this data directly, but the reading is poor, so it has the name of the data.And the value of this variable name cannot

Static use in Java1. Static variables (class variables).2. Static methods (class methods). In fact, the main method we've been writing about is static methods.Need to note:1 static members can be called directly in a static method, but not non-static members directly.If you want to invoke a non-static variable in a static method, you can access the non-static variable by creating the object of the class and then through the object.2, in the ordinary member method, you can directly access the sam
