这个有问题,构造函数是没有参数返回的,把void去掉public Student
你的构造函数写错了
你有三个Student的构造函数,你全部写成了方法(因为你在前面加了void)
public void Student(String name, String addr, char sex, int age, int math,int english) {}
public void Student(int math, int english) {}
public void Student() {}
正确的写法是
public Student(String name, String addr, char sex, int age, int math,int english) {}
public Student(int math, int english) {}
public Student() {}
public void Person()
{
}
构造方法不能加void， 直接用public Person(){}，把所有构造方法都改一下
构造函数不需要返回值的
把所有构造函数的void去掉
