java - 可以找到错误

Question

因此，在我的 Java 在线类(class)中，我必须包含变量并提供 set 和 get 方法来获取类(class)讲师的姓名，并显示消息:欢迎来到以下类(class)的成绩册: 本类(class)由以下人员介绍:

类(class)成绩簿:

public class GradeBook
{
    private String courseName;
    public String courseTeacher;

    public GradeBook( String name, String teacher )
    {
        courseName = name;
        courseTeacher = teacher;
    }

    public void setCourseName( String name )
    {
        courseName = name;
    }

    public String getCourseName()
    {
        return courseName;
    }

    public void setCourseTeacher( String teacher )
    {
        courseTeacher = teacher;
    }

    public String getcourseTeacher()
    {
        return courseTeacher;
    }

    public void displayMessage()
    {
        System.out.printf( " Welcome to the grade book for:/n%s!\n" ,         getCourseName() , "This course is presented by: \n%s\n!" ,getCourseTeacher() );
    }

}

主类:

import java.util.Scanner;

public class GradeBookTest
{
    public static void main( String[] args)
    {
        Scanner input = new Scanner( System.in );
        GradeBook myGradeBook = new GradeBook( "Cs101","Ciro" );

        System.out.println( "Please enter the course name:" );
        String theName = input.nextLine();
        myGradeBook.setCourseName( theName );

        System.out.println( "Please enter instructor name:" );
        String theTeacher = input.nextLine();
        myGradeBook.setCourseTeacher( theTeacher );

        System.out.println();
        myGradeBook.displayMessage();
    }
}

错误:

cannot find symbol method getCourseTeacher()      GradeBook      line 38

Answer 1

Java 区分大小写，因此方法定义中的 getcourseTeacher 应为 getCourseTeacher(大写的 C):

public String getcourseTeacher()
                 ^ THIS
