可以帮我看看哪里出错么 谢啦 ， 弄了半天没找出错误
public class MyExercise11_2 {public static void main(String[] args) {

java super关键字问题 --------------------编程问答-------------------- 没错误不好吗？你的问题是什么 --------------------编程问答-------------------- 错了 有错误 但不知道在哪 --------------------编程问答--------------------
错了 有错误 但不知道在哪 --------------------编程问答-------------------- 哥哥，你是写Java的么？你的代码谁写的呀？
这不是瞎写么 --------------------编程问答-------------------- 放到环境下测试就行。。 --------------------编程问答--------------------
怎么说 ，最近学到 super了，但有点乱，求大神指导 --------------------编程问答-------------------- 测过了， 但不知道super.Person(String name, String address, String cellNumber, String email);怎么错了 --------------------编程问答--------------------
class Student extends Person {
public static int grade;
Student() {
super.Person(String name, String address, String cellNumber, String email);
}
public String toString(String name) {
return "student" + " " + name;
}
}
这个是啥玩意？你想写类的继承？也不是这么些的啊。你看过java的书籍么？
这个类应该这么写：
class Student extends Person {
public int grade;
public Student(String name, String address, String cellNumber, String email, int grade) {
super(name, address, cellNumber, email);
this.grade = grade;
}
public String toString(String name) {
return "student" + " " + name;
}
}
别的类我就不给你写了。自己去看书吧，以为啥重大的问题呢。原来你一点Java都不懂，这里就是乱拼代码。去看书吧！ --------------------编程问答--------------------
测过了， 但不知道super.Person(String name, String address, String cellNumber, String email);怎么错了 --------------------编程问答-------------------- 受教 --------------------编程问答--------------------
小弟刚学 ，，不好意思 --------------------编程问答--------------------
呵呵，给你点建议：先看完一般java的基础知识的书籍，起码把java的基本语法看完。我知道你中间一定会遇到很多问题，你可以拿张纸先记录下来。然后接着看。你会发现你很多问题，是因为在你看的书后面的章节里面写着的。你先看基础，在写代码练习，就不会有上面的笑话了。努力！！！ --------------------编程问答-------------------- 没搞清父类的构造函数是怎么用的 --------------------编程问答-------------------- 继承关系中，如果在子类中想直接调用父类的构造函数进行初始化，super.Person(String name, String address, String cellNumber, String email); 这样是不行的。super.methodName是调用父类的方法，这些方法中不包括构造函数。改成super(String name, String address, String cellNumber, String email);试试，这样就是调用父类的对应参数列表的构造函数。
补充：Java , Java SE
