解析:将符号引用转成直接引用; 初始化:激活类的静态变量的初始化Java代码和静态Java代码块。 初始化类中属性是静态代码块的常用用途,但只能使用一次。 (二)静态代码块的初始化顺序 class Parent{ static String name = "hello"; { System.out.println("parent block"); } static { System.out.println("parent...

static关键字:静态的、公共的。 非静态的方法可以使用静态的内容。 三、 block块 块,即{},可以分为: 静态块,仅在类的第一次使用时加载。 构造块,先于构造器执行,每创建一个对象执行一次。 乐字节原创,转载请注明出处。 欢迎继续关注乐字节,后续继续Java技术分享 ...
We can make any variable, method, block or nested class static by preceding the keyword static. Only a static method can change the value of static variable. You cannot use a static variable from a non-static method, and vice versa. ...
java 中最重要的一个特性就是封装,这个就要用到了private protected default public 来控制访问权限。 其中有是不好理解的是private . private 的访问权限:仅此类,意思是说(1)只有本类中的方法才能访问它,(2)它的字类是不可以访问的,(3)还有就是如果在其它类中实例化这个类,然后调用这份额方法也是不行的。(...

All we have to do is declare aninitblock inside thecompanionobjectof a class.This way, we get the same behavior as Java’sstaticblock. Put simply, when the JVM is going to initialize the enclosing class, it will execute theinitblock inside thecompanion object. ...
In our example, we reiterate this point by checking, before and after our scoped block, that our static methodnamereturns a real value. 5. Mocking a Static Method With Arguments Now let’s see another common use case when we need to mock a method that has arguments: ...
