Question

Java programming help? (Code included)

I attached the instructions in the question here and I will include my code in the comments. Note that I have already finished the Course program, but the code I am entering in the comments is for Student. I did that one but I was experiencing errors at the end of the program. Tester was hard to do. Thanks.

Answer 1

Student code:

public class Student{
private String studentName;
private Course[] allCourses;

public void setName(String name){
this.studentName = name;
}

public void setAllCourses(Course[] allCourses){
this.allCourses = allCourses;
}

public String getName(){
return studentName;
}

public Course[] getAllCourses(){
return allCourses;
}

public Student(){
this.studentName = "";
this.allCourses = new Course[1];
}
public Student(String name){
this.studentName = name;
this.allCourses = new Course[4];
}

public Student(String name, Course[] c){
this.studentName = name;
allCourses = c;
}

public int getTotalCreditHours(){
int total = 0;
for(int i=0; i<allCourses.length; i++){
total += allCourses[i].getCreditHours();
}
return total;
}

public void print(){
System.out.println(studentName + " " + getTotalCreditHours() + "hrs");
for(int i=0; i<allCourses.length; i++){
System.out.println(allCourses[i].getCourseTitle());
}
return total;
}


}

Answer 2

Course program:

public class Course{
private String courseNumber;
private String courseTitle;
private int creditHours;

public void setCourseNumber(String courseNumber){
this.courseNumber = courseNumber;
}

public void setCourseTitle(String courseTitle){
this.courseTitle = courseTitle;
}

public void setCreditHours(int creditHours){
this.creditHours = creditHours;
}

public String getCourseNumber(){
return courseNumber;
}

public String getCourseTitle(){
return courseTitle;
}

public int getcreditHours(){
return creditHours;
}

public Course(){
this.courseNumber = "";
this.courseTitle = "";
this.creditHours = 0;
}

public Course(String courseNumber, String courseTitle, int creditHours){
courseNumber = courseNumber;
courseTitle = courseTitle;
creditHours = creditHours;
}
}

Answer 3

Errors in Student program:

public void print(){
System.out.println(studentName + " " + getTotalCreditHours() + "hrs");
for(int i=0; i<allCourses.length; i++){
System.out.println(allCourses[i].getCourseTitle());
}
return total;
}
