C++/JAVA/C#子类调用父类函数情况总结

class Base
{
 public:
   Base(int b) : m_b(b)
   {
   }
 private:
   int m_b;
 };
 class Derived : public Base
 {
 public:
   //普通派生类构造函数的写法
   Derived(int b, int d) : Base(b), m_d(d)
   {
   }
 private:
   int m_d;
};

class Person {
 private String name;
 private int age;
 private boolean sex;
 public Person() {
 this("jadeshu", 22, true); // 必须在第一行 不能同时调两个不同的构造函数
 }
 public Person(String name,int age, boolean sex) {
 this.name = name;
 this.age = age;
 this.sex = sex;
 }
}

class Man extends Person {
 public Man(String name, int age) {
 //System.out.println("====");
 //不能再非构造函数中使用this调用构造函数
 super(name, age, true); // 必须在第一行
 }
}

class Person {
 private String name;
 private int age;
 private boolean sex;
 public Person() {
 this("jadeshu", 22, true); // 必须在第一行
 }
 public Person(String name, int age, boolean sex) {
 this.name = name;
 this.age = age;
 this.sex = sex;
 }
 public void person_test() {
 System.out.println("Person person_test() called!");
 }
 public void sub_test() {
 System.out.println("Person sub_test() called!");
 }
}
class Man extends Person {
 public Man(String name, int age) {
 //System.out.println("====");
 super(name, age, true); // 必须在第一行
 }
 public void sub_test() {
 System.out.println("Man sub_test() called!");
 }
 public void sub() {
 person_test();   // 直接调用父类的函数[子类不存在person_test函数]
 super.sub_test(); // 调用父类中的函数[子类和父类存在同名函数时使用super.XXX]
 System.out.println("Man sub() called!");
 }
