of all objects. Our construction method is to target the corresponding object of the unique initialization.So which of the constructors that constructs the code block runs first? Let's look at the code:Class Person{private String name;{ The first constructs a code block SYSTEM.OUT.PRINTLN ("The 1th code block of the person class is run");} Person () {System.out.println ("No parameter constructor is run"); this.name = "Baby";} Person (String name) {System.out.println ("the name parameter constru

And the previous basic type and the reference type of heap, stack allocation, can be understood as follows: Basic type General data is Small. So with the stack, the speed is fast Reference types have a count and heap to control the release mechanism Values vs. objectsAs mentioned above, the relationship between variables, values, and objects is summarized as Follows: var variable = value; There are only two types, one is a basic type (similar to constant Data) an

When I was a child, I used building blocks. We all know that different effects can be achieved through different combinations. In fact, this principle can also be used in innovative design-by modularized the product system, then, different modules can be combined to create different products. In the past era of discrete products, this design concept was hard to implement, but with the increasing strength of

products is that it is from the UML1.4 after the emergence of a new structure of things (note: This is according to the author's investigation, remains to be verified), to indicateA physical component of a system that is often used to represent a file.4) and the difference between the activity class is that its shape has undergone some changes, the two-layer vertical line instead of bold black-framed lines, more easy to distinguish with the class.

In front of the words: recent free time learning angular 2, national day time to see the official website of QuickStart, also wrote an article, just a Hello World demo. After continuing to read a project tutorial, just start still can keep up, when the back is more confusing. Indeed, for beginners, it is more troublesome to understand a framework. So stop the project and start looking at how angular's overall framework is, contact the project, analyze it, take it slow. Learning Link: China Civi
