JAVA review 3 Java classes and objects I wrote two decommissioned articles, so I wrote something useful on my blog. If you want to learn JAVA, you must understand the relationship between classes and objects ,, because a major feature of JAVA is object-oriented .. Let's take

Java Web Review Article 10 JSTL and Java Web Article 10 jstl JSTL (JSP Standard Tag Library) JSP Standard Tag Library. It aims to simplify JSP development. Without JSTL, We need to write a large number of custom tags during development, which will undoubtedly increase the development difficulty, with JSTL, we do not need to write common labels (unless special), w

There are two articles written in the front, so write something useful on your blog, and if you want to learn Java, you have to understand the relationship between classes and objects, because one of the main features of Java is Object-oriented.Let's take a look at the concepts of classes and objects: (in fact, they hate these concepts at school) Object : An object is an instance of a class that h

Java review Summary: Java Object-Oriented Programming-exception capture and handling, packet and access control permissions 1. Exceptions are a type of command flow that causes program interruption. When exceptions occur, if they are not properly processed, the program will be interrupted. 2. for exceptions, try... Try... Catch... Finally, catch exceptions in th

AWT: Abstract window Toolbox, Awt+ifc==swing,swing is a component based on the AWT architecture, but processing events still use AWT The user interface class that swing uses to be drawn, JavaFX may replace it, and AWT is used for the underlying mechanism. The user can specify "look and feel", and metal is a "look and feel" specifically for Java In the Swing library, the JFrame class is used to describe the top-level form, which is one of the few

The This keyword in java, this can call the Class's member variables and member methods, and this can also call a constructor method in the Class. in this way, it is worth noting thatYou can only use the This keyword in the first sentence of the parameterless constructor method to invoke a parameter construction method. public class anythting{ public anythting () { This ("the this call has a parameter constructor method"); SYSTEM.OU

Java Web Review 11th filters (with Chinese garbled characters) and Java Web 11th1: filter concept A filter is an intermediate component that requests the target resource. A sewage purification device is needed to convert the sewage into pure water, which is like a filter. Then I use graphs to indicate the process of running the filter (multiple filters can be inc

() invokes other methods within the same class. Super () and this () all need to be placed in the first row within the construction method. Although you can call a constructor with this, you cannot call Two. This and super can not appear in a constructor at the same time, because this is bound to call other constructors, the other constructors will inevitably have a super statement exists, so in the same constructor has the same statement, it loses the meaning of the statement, the compil

and IteratorWe use the Foreach method to iterate through the array , but we can also use foreach to traverse the subclass class of Collection such as ArrayList, because Collection inherits iterable Port , so as long as our class inherits or implements the Iterable interface, our class can be traversed by foreach, as follows:Import Java.util.iterator;public class Holditerable implements iterableIt is important to note that although foreach can iterate through the array and the Iterable interface
