我必須設計一個由2個子類組成的類。假設A和B和B也有2個子類。這部分真的不重要，因爲我用不同的名字完成了這一切。Java，調用方法和覆蓋
我努力嘗試運行我的代碼。我有代碼，但我得到2錯誤。我無法弄清楚如何解決它。
的錯誤有以下幾種：
aaa1.java:147：找不到符號
符號：構造員工（java.lang.String中，java.lang.String中，java.lang.String中， java.lang.String）
location：class Employee
super（name，address，phone，email）;
^
aaa1.java:179：找不到符號
符號：構造員工（java.lang.String中，java.lang.String中，java.lang.String中，java.lang.String中）
位置：類員工
super（姓名，地址，電話，電子郵件）;
我的代碼：
import java.util.*;
public class aaa1 {
public static void main(String[] args){
Person p = new Person("J11h", "123 ABC St", "908-123-456", "[email protected]");

你能幫幫我嗎？
請發表評論，表明錯誤的行號。 – Razib 2015-04-04 21:55:30
你有沒有嘗試把兩個類放入單獨的文件？ – clearlight 2015-04-04 21:56:05
@Razib在Employee類中發生錯誤。它在超級構造函數內。此部分： 「公開職員（字符串名稱，字符串地址，字符串電話，字符串電子郵件，字符串辦公室，雙重工資，日期dateHired）{超級（姓名，地址，電話，電子郵件）;」 – Joseph 2015-04-04 21:59:47
