而且由于InsideClass是private的,所以我们如果不看代码的话根本看不到这个具体类的名字,所以说它可以很好的实现隐藏。 2.可以无条件地访问外围类的所有元素 package insidecategory; public class TagBean { private String name="liutao"; private class InTest { public InTest() { System.out.println(name); ...
在上面的示例程序中,尽管外部类 OutsideClass 的属性是用 private 修饰的,内部类 InsideClass 依然可以对这些属性进行无缝访问。此时教学重点在于从两个角度给学生讲解内部类对外部类的访问:一个角度是把内部类看成外部类的一个成员,外部内的一个成员当然可...

A nested class is a member of its enclosing class. Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private. Static nested classes do not have access to other members of the enclosing class. As a member of theOuterCl...
First, there is no need to initialize the signing or verification engine, as it will be re-initialized inside the constructor and the verify method. Secondly, for verification to succeed, the specified public key must be the public key corresponding to the private key used to generate the ...
