I did this code ( this here is just a piece of it), and there's supposedly an incomplete function in there.
I'm not sure what how to solve this. I suppose the boolean is wrong? I indicated where the problem is in the code.
public class Person
{
private String firstName;
private String lastName;
private String ID; // user ID
private String password;
private int userType; // 1 student 2 faculty
public Person()
{
}
public Person(String ID, String firstName, String lastName, String password, int userType)
{
this.ID = ID;
this.firstName = firstName;
this.lastName = lastName;
this.password = password;
this.userType = userType;//1 faculty 2 student
}
public String toString()
{
return ID+ " " + Application.addSpaces((firstName + " " + lastName),18);
}
public boolean equals(Object theOtherObject)
{
// YOU CAN CHANGE EVERYTHING IN THIS FUNCTION INCLUDING THE STAMENTS:
// boolean result = false;
// return result;
boolean result = false;
// INCOMPLETE FUNCTION
// ooooooooooooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// ooooooooooooooooooo
// oooooooo ooooooooo
// ooooooooooooooooooo
return result;
}
public boolean validation(String ID, String password)
{
return ( this.ID.equals(ID)&& this.password.equals(password) );
}
public int getUserType()
{
return userType;
}
public String getUserID()
{
return ID;
}
}The same with this one here:
public class Application
{
private Scanner keyboard;
private Person[] userDatabase;
private Course[] courseDatabase;
private int numberOfUsers;
private int numberOfCourses;
private Person currentUserObject;
public static String addSpaces(String input, int fullLength)
{
String output= input;
int extraZeros = fullLength-input.length();
for(int i=0; i<extraZeros; i++)
{
output = output +" ";
}
return output;
}
public Application()
{
currentUserObject = null;
userDatabase = new Person[20];
courseDatabase = new Course[10];
numberOfUsers = 0;
numberOfCourses = 0;
keyboard = new Scanner(System.in);
addRecords();
}
private void addRecords()
{
// Create Users
userDatabase[numberOfUsers++] = new Student("92038201", "Ilyas", "Uyanik", "Computer Science", "1956", 2, 1);//0

// Create Courses
courseDatabase[numberOfCourses++] = new Course("1320", "Intro to Computer Science", "52037101", 4);
courseDatabase[numberOfCourses++] = new Course("1410", "Data Structures", "10132103", 4);
courseDatabase[numberOfCourses++] = new Course("2430", "Artificial Intelligence", "32546104", 3);
// Enrollment
((Student)userDatabase[0]).addClass(courseDatabase[0]);
((Student)userDatabase[1]).addClass(courseDatabase[0]);
((Student)userDatabase[2]).addClass(courseDatabase[0]);
((Student)userDatabase[3]).addClass(courseDatabase[0]); // 1320, full
((Student)userDatabase[4]).addClass(courseDatabase[1]);

}
private int existingCourse(String courseNumber)
{
int result = -1;
for(int i=0; i<numberOfCourses;i++)
{
if( courseDatabase[i].getNumber().equals(courseNumber) )
{
result = i;
}
}
return result;
}
private boolean existingUser(String ID)
{
// RETURN FALSE IF THERE IS NO USER WITH THE GIVEN ID
// RETURN TRUE OTHERWISE
// YOU CAN CHANGE EVERYTHING IN THIS FUNCTION INCLUDING THE STAMENTS:
// boolean result = false;
// return result;
boolean result = false;
// INCOMPLETE FUNCTION
// ooooooooooooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// oooooooo ooooooooo
// ooooooooooooooooooo
// oooooooo ooooooooo
// ooooooooooooooooooo
return result;What is wrong with the boolean?
