Question

我会正确的。我有一个顾问班，我的司机叫来自建议班。

我的Advisee类与错误问题有关：

public String clearedToGraduateMessage(Advisee advisee1, Advisee advisee2,  
        Advisee advisee3, Advisee advisee4, Advisee advisee5)  
    {  
        if (graduationRequirements)  
        {    
            graduationMessage = ("\nYes - all requirements have been met");  
        }
        if (!graduationRequirements)
        {  
            graduationMessage = ("No - ");  
            if (getHoursCompleted() < 120)  
            {        
                graduationMessage += (" not enough hours;");  
            }
                else if (majorSheet == false)  
                {
                    graduationMessage += (" not completed major sheet;");
                }  
                else if (intentToGraduate == false)  
                {
                    graduationMessage += (" not filed intent to graduate");
                }  
            }  

        if (advisee1.metGraduationRequirements(advisee1, advisee2, advisee3, advisee4, advisee5)   
            == true)  
            advisee1.graduationMessage = ("\nYes - all requirements have been met");  
        else  
            {  
                advisee1.graduationMessage = ("No - ");  
                if (advisee1.hours < 120)  
                    advisee1.graduationMessage += (" not enough hours;");  
                else if (majorSheet == false)  
                    advisee1.graduationMessage += (" not completed major sheet;");  
                else if (intentToGraduate == false)  
                    advisee1.graduationMessage += (" not filed intent to graduate");  
            }

“if（advisee1.metGraduationRequirements（advisee1，advisee2，advisee3，advisee4 advisee5）== true）”再次重复4次作为相应的引用，为了不发布大量代码，我不会发布那。

驱动程序如下所示：

case 4: //display all advisees that have been cleared to graduate  
                    strClearedToGraduateMessage = clearedToGraduateMessage(advisee1,   
                        advisee2, advisee3, advisee4, advisee5);

它在switch语句中，因为我正在使用菜单。

我尝试编译时出现的“唯一”错误是：

Proj4.java:142: error: cannot find symbol
                    strClearedToGraduateMessage = clearedToGraduateMessage(advisee1,   
                                                  ^
  symbol:   method clearedToGraduateMessage(Advisee,Advisee,Advisee,Advisee,Advisee)
  location: class Proj4
1 error

如果有人能帮助我搞清楚这个错误，我们将不胜感激。感谢。

您尚未显示所有相关代码，但似乎在Proj4（驱动程序类）中，您尚未创建要引用的Advisee对象的实例。你需要这样的东西：

Advisee myAdvisee = new Advisee();
String result =  myAdvisee.clearedToGraduateMessage(...);

除非您的Advisee方法是静态的，否则您需要创建要引用的对象（即使是静态的，您仍需要引用类名）。

我建议花些时间阅读The Java Tutorials/Classes

Java错误，可怕的“无法找到符号”
