首先执行静态代码块,然后执行构造方法。静态代码块在类被加载的时候执行,而构造方法是在生成对象的时候执行;要想调用某个类来生成对象,首先需要将类加载到 Java 虚拟机上(JVM),然后由 JVM 加载这个类来生成对象。类的静态代码块只会执行一次,是在类被加载的时候执行的,因为每个类只会被加载一次,所以静态代码块也...

java中接口interface和private私有内部类怎样一块配合着用? 3.接口interface和private内部类协同工作【新手可忽略不影响继续学习】 马克-to-win:由于是private内部类,外面无法访问甚至无法看到你编的源代码(如果在不同的包中),非常安全。外界只能调用接口中的方法。下例中访问不了Core,甚至你不知道有Core的存在。给你...
在Java接口中定义私有方法非常简单,只需要在方法前面加上private关键字即可。私有方法的定义可以在Java 9之后的版本中使用。 下面是一个示例代码,演示了如何在接口中定义私有方法: publicinterfaceCalculator{defaultintadd(inta,intb){returna+b+helper();}privateinthelper(){return10;}} 1. 2. 3. 4. 5. 6....
