这是我得到的错误:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
TeamLeader cannot be resolved to a type
at TeamLeadDemo.main(TeamLeadDemo.java:26)
这是我的代码:
import java.util.Scanner;
public class Employee {
public String empName, empNumber, hireDate;
public class TeamLeadDemo {}
public Employee(String empName, String empNumber, String hireDate) {
this.setEmpName(empName);
this.setEmpNumber(empNumber);
this.setHireDate(hireDate);
}
public void setEmpName(String empName) {
this.empName = empName;
}
public void setEmpNumber(String empNumber) {
this.empNumber = empNumber;
}
public void setHireDate(String hireDate) {
this.hireDate = hireDate;
}
public String getEmpName() {
return empName;
}
public String getEmpNumber() {
return empNumber;
}
public String getHireDate() {
return hireDate;
}
public class ShiftSupervisor extends Employee {
public double annualSalary, annualProduction;
//constructor
public ShiftSupervisor(String empName, String empNumber,
String hireDate, double annualSalary,
double annualProduction) {
super(empName,empNumber, hireDate);
this.setAnnualSalary(annualSalary);
this.setAnnualProduction(annualProduction);
}
public double getAnnualSalary() {
return annualSalary;
}
public double getAnnualProduction() {
return annualProduction;
}
public void setAnnualSalary(double annualSalary) {
this.annualSalary = annualSalary;
}
public void setAnnualProduction(double annualProduction) {
this.annualProduction = annualProduction;
}
public String toString() {
return "Name: "+ getEmpName() + "\nEmpID: "+ getEmpNumber()
+ "\nHire Date: "+ getHireDate() + "\nAnnual Salary: "
+ annualSalary + "\nProduction: "+ annualProduction;
}
public class employeeStart {
public void main(String[] args) {
String name, id, date;
double sal, prod;
//create scanner object
Scanner keyboard = new Scanner(System.in);
//inputting data
System.out.println("Enter Name: ");
name = keyboard.nextLine();
System.out.println("Enter id: ");
id = keyboard.nextLine();
System.out.println("Enter Hire Date: ");
date = keyboard.nextLine();
System.out.println("Enter Annual: ");
sal = keyboard.nextDouble();
System.out.println("Enter production: ");
prod = keyboard.nextDouble();
//instantiating object
ShiftSupervisor pw = new ShiftSupervisor(name, id, date, sal, prod);
//outputting data
System.out.println("Employee Details: \n" + pw);
}
}
public class TeamLeader {
public double monthlyBonus;
public int minTraining, trainingPresent;
public TeamLeader(double monthlyBonus, int minTraining, int trainingPresent) {
this.setMonthlyBonus(monthlyBonus);
this.setMinTraining(minTraining);
this.addtrainingPresent(trainingPresent);
}
public void setMonthlyBonus(double monthlyBonus) {
this.monthlyBonus = monthlyBonus;
}
public void setMinTraining(int minTraining) {
this.minTraining = minTraining;
}
public void setTrainingPresent(int t) {
trainingPresent = t;
}
public void addtrainingPresent(int hours) {
trainingPresent += hours;
}
public double getMonthlyBonus() {
return monthlyBonus;
}
public int getMinTraining() {
return minTraining;
}
public int getTrainingPresent() {
return trainingPresent;
}
public String toString() {
return "Bonus: "+ getMonthlyBonus() + "\nMinimum Training: "
+ getMinTraining() + "\nAttendence: "+ getTrainingPresent();
}
}
}
}
另外,我在一个单独的类中声明了这一点:
import java.util.Scanner;
public class TeamLeadDemo extends Employee {
public TeamLeadDemo(String empName, String empNumber, String hireDate) {
super(empName, empNumber, hireDate);
// TODO Auto-generated constructor stub
}
public static void main(String[] args) {
double sal;
int min, atten;
//create scanner object
Scanner keyboard = new Scanner(System.in);
//inputting data
System.out.println("Enter minimum training: ");
min = keyboard.nextInt();
System.out.println("Enter id: ");
atten = keyboard.nextInt();
System.out.println("Enter Bonus: ");
sal = keyboard.nextDouble();
//instantiating object
ShiftSupervisor pw = new TeamLeader(sal, min, atten);
//outputting data
System.out.println("Employee Details:\n" + pw);
}
}
是什么导致此错误,我该如何解决?
编辑:缩进,空格,命名约定和可读性问题已得到解决。
最佳答案
问题在于TeamLeader
似乎是一个内部类(很难说,您的缩进是不好的),并且由于它不是静态的,因此您无法单独实例化它。
您要么需要将TeamLeader
设为自己的类,要么将其设为static
类并将其实例化为Employee.TeamLeader
(或者无论父类是什么,您的缩进在这里实际上都无济于事)。
