innerclass分为四种
一.staticinnerclass(静态内部类)
1.the simplest form of inner class
2.Can‘t hava the same name as the enclosing class
3.Compiled into a comletely separate .class file from the out class
4.Can acess only statci members and methods fo the enclosing calss ,including private static members
5.Create an instance of a static inner class out of enclosing class :new outerclass.innerclass()
package innerClass; class staticInner { private static int n=10; public static void dosomething() { System.out.println(n); } public static class Inner { public void test() { System.out.println(n); dosomething(); } } } public class staticInnerClassTest{ public static void main(String[] args) { staticInner.Inner inner=new staticInner.Inner(); inner.test(); } }
上面第四点,只能访问包含他的类的静态成员变量和静态方法 例如上面的 inner类 只能访问 n变量 和staticdosomething方法
如果把上面的的定义变量n和方法的修饰符static去掉 就会出错,例如去掉变量n前的static修饰符 错误提示为Cannot make a static reference to the non-static field n
不能使一个静态n引用为非静态字段,差不多就是这个意思,就是不能访问包含它的类的非静态字段和方法
