I. Introduction to Objects 1. Abstract procedure Alan Kay has summed up the first successful object-oriented language, and the five basic features of Smalltalk, one of the languages on which Java is based, which represent a purely object-oriented approach to programming 1) everything is Object . 2) the program is a collection of objects that tell ea

Basic applications with exceptions in Java (1), Java applications ( In Java, we treat exceptions as an object. It is the introduction of the exception mechanism that makes our programs more robust. An exception indicates an abnormal condition or an error condition, which is simply an event that interrupts the normal in

Abstraction:Abstraction is to ignore those aspects irrelevant to the current target in a topic, so that you can pay more attention to the aspects related to the current target. Abstraction is not intended to understand all the problems, but to select a part of the problem. Abstract: Process abstraction and data abstraction.2. Inheritance:Inheritan

1 Java Virtual machine-to-memory management Java virtual machines divide memory into a number of different zones when executing Java programs, each of which has its own different uses, as well as the creation and destruction times. Some zones start with the start of a virtual machine, Some zones start and end depending

In actual programming, there are often such "datasets", their values are stable in the program, and the elements in the "dataset" are limited. For example, seven data elements from Monday to Sunday constitute a "dataset" for a week, and four data elements for spring, summer, and autumn constitute a "dataset" for the Four Seasons ". In Java, the easiest way to think of such a dataset is to write it like this. Let's take a Friday workday as an example:

, which contains some static utility methods, including a fill (). This fill () only copies the reference of the same object to the entire container, and it can only work for list, not set and map. Disadvantages of containers: Unknown Object TypesThe disadvantage of Java containers is that when an object is put in the container, the object type information is lost. This is because developers of the container class will not know what type of objects yo
