In the first week, I learned about the installation of the JDK and the configuration of the environment, and initially learned about the differences between Java and C, and learned about Java variables, basic data types, and object-oriented foundations. And I have done some simple Java program writing.(1) Learn why abstract classes are used, and abstract classes are used so that programmers do not forget to replicate when they inherit.Abstract class Printer{void Open (){System.out.println ("open

. For example, you can use LESS or SCSS for CSS code and TypeScript for JavaScript code. You can list the resource files that use the extended syntax to yii \ web \ AssetBundle: css and yii \ web \ AssetBundle: js of the resource package, as shown below: class AppAsset extends AssetBundle{ public $basePath = '@webroot'; public $baseUrl = '@web'; public $css = [ 'css/site.less', ]; public $js = [ 'js/site.ts', ]; public $depends = [ 'yii\web\YiiAsset', 'yii\bootstrap\BootstrapAsset', ];} Wh
