java gui builder

Today, I looked at the construction mode and came up with a bit of experience. Apply a theory first: the construction mode separates the internal appearance of a product from the product generation process, so that a building process generates product objects with different internal appearances. The construction mode allows the product's internal appearance to change independently, so that the customer does not have to know the details of the product's internal composition. The construction mode

by a non static object. We can find the corresponding evidence from the output results.It is necessary to summarize the process of creating the object here. Consider a class named dog:(1) When an object of type dog is first created, or the dog class's static method/static field is first accessed, the Java interpreter must find Dog.class (search in the predefined classpath).(2) After the Dog.class is found (it creates a class object that will be learn

The Java GUI (graphical user interface) consists of various components, mainly the AWT components (java.awt) and the more powerful swing components (javax.swing).Components can be divided into container components and non-container components. A container component is a component that can contain other components, and is divided into top-level containers and general-purpose containers. Non-container compone

First, the builder model(Builder)The factory class pattern provides the pattern of creating a single class, while the builder pattern is to centralize the various products to manage, to create composite objects, so-called composite objects that refer to a class that has different properties, in fact the builder pattern

Java is a very powerful programming language, but Java's GUI power has always been its Achilles heel. Although Java offers 2 graphics solutions, AWT and swing. However, these 2 graphics libraries are very limited in functionality, and they do not bring more user experience. And AWT and swing are slow to update. All the while to the

task. Second, the flexibility of such a constructor is not high, and you have to provide some meaningless parameter values at the time of invocation, for example, Dodocontact ("Ace",-1, "SH"), obviously the age of negative is meaningless, but you do not do so, to conform to Java specifications. If such code is released, the maintainer behind it will have a headache because he doesn't know what the 1 means. For such cases, it is very well suited to us

Obviously, it doesn't make sense to have a negative age, but you don't need to do this, so it can comply with Java specifications.
