成员内部类代码示例

public class Teacher {
    //成员变量
    private String teacherName;
    public Teacher() { }
    public Teacher(String teacherName) {
        this.teacherName = teacherName;
    }
    //成员内部类
    //可以继承和实现接口
    class Inner extends Object implements Cloneable {
        private String name;
        不能有静态成员
        //private static int age = 10;
        public Inner(String name) {
            this.name = name;
        }
        public void showTeacherInfo(String name) {
            System.out.println("传入 name = " + name);
            System.out.println("内部成员变量 name = " + this.name);
            System.out.println("外部成员变量 name = " + Teacher.this.teacherName);
        }
    }
    public static void main(String[] args) {
        //创建外部类对象
        Teacher teacher = new Teacher("形参1");
        //通过外部类对象创建内部类对象
        Teacher.Inner inner = teacher.new Inner("内部类");
        inner.showTeacherInfo("形参");
    }
