获取“找不到合适的构造函数”在课程c01，co2中。
它也没有让我设置学生，教学等等。它给了我一个“找不到符号”我有6个班级，这是主要班级。我宣布所有的变量，集合，在其他类中获取，现在我正在尝试执行主类（这一个）好的我添加了类的主要用途。
public class Course

答案 0 :(得分：0)
这些是您提供的构造函数。
public Course(String title, String instructor, double price, Date startDate, Date endDate)
public Course()
根据课程c01对象，您看起来有几个问题。首先，错误的括号（和“Uta”2015，对构造函数也无效。
Course co1 = new Course ("OnlineCourse",("Java 1","PROGRAMMING", "Davis", 125.00, new Date(1,1,2015), new Date(1,15,2015), "Uta" 2015);
我不确定它是否只是一个拼写错误，但没有合适的构造函数，正如错误所述。
尝试用此替换它，看看你得到了什么。
Course co1 = new Course ("Java 1","Davis", 125.00, new Date(1,1,2015), new Date(1,15,2015));
对于找不到符号错误，看起来您可能没有正确引用枚举。
c1.setCType(Customer.customerType.STUDENT);
看起来应该是，
c1.setCType(Customer.CustomerType.STUDENT);
