    <p>I am trying to use a toString() method in order to print out some private fields. However, whenever I attempt to send an object of the appropriate class to a print method, it only prints out the default values of each of the fields, no matter what I change them to. Any help would be greatly appreciated :) Here is the class with the toString() method (it also overrides another class which is where the getters are coming from). Sorry I am slow at editing this post. Not familiar with the text editor on here.</p> <p>Person Class </p> <pre><code>public class Person { // Declare all the fields as strings private String firstName = "", lastName = "", address = "", zipcode = "", phone = ""; // There are accessors and mutators for these as well public String toString() { String str = "First name: " + firstName + "...Last name: " + lastName + "... Street address: " + address + "... Zipcode: " + zipcode + "... Phone number: " + phone; return str; } </code></pre> <p>Student Class</p> <pre><code> public class Student extends Person { // declare fields that are not in Person private String major = ""; private double gpa; // Declare accessor and mutator methods for the fields public String getMajor() { return major; } public void setMajor(String major) { this.major = major; } public double getGpa() { return gpa; } public void setGpa(double gpa) { this.gpa = gpa; } // Create a toString method that overrides the one in Person public String toString() { String str = "First name: " + getFirstName() + "...Last name: " + getLastName() + "... Street address: " + getAddress() + "... Zipcode: " + getZipcode() + "... Phone number: " + getPhone() + "... Grade point average: " + getGpa() + "...Major: " + getMajor(); return str; } } </code></pre> <p>Here is the entire main class... a lot of it is tedious code since it is a homework assignment, but the main idea is to: "Write an application named CollegeList that declares an array of 4 “regular” CollegeEmployees, 3 Faculty, and 7 Students. Prompt the user to specify which type of person’s data will be entered (‘C’, ‘F’, or ‘S’), or allow the user to quit (‘Q’). While the user chooses to continue (that is, does not quit), accept data entry for the appropriate type of person. If the user attempts to enter data for more than 4 college employees, 3 faculty, or 7 students, display an error message. When the user quits, display a report on the screen listing each group of Persons under the appropriate heading “College Employees,” “Faculty,” or “Students”. If the user has not entered data forone or more types of persons during a session, display an appropriate message under the appropriate heading.</p> <p>MAIN CLASS</p> <pre><code>import java.util.Scanner; // Needed for Scanner class public class CollegeList { /** * @param args the command line arguments */ public static void main(String[] args) { // Declare the arrays of people Person[] people = new Person[14]; // These three arrays are being made to print out the types of people // at the end neatly Faculty[] fArray = new Faculty[4]; Student[] sArray = new Student[7]; CollegeEmployee[] cArray = new CollegeEmployee[3]; // Prompt for users input System.out.print("Please choose the type of person you are entering " + "data for.\nFor a student enter \"S\"; for a faculty member " + "enter \"F\"; for a college employee enter \"C\"; and to quit " + "enter \"Q\": "); Scanner keyboard = new Scanner(System.in); String type = keyboard.next(); // the type of person System.out.println(); // initialize counts of persons so that user does not enter more int facultyCount = 0; int studentCount = 0; int employeeCount = 0; // initialize index of the array to 0 int index = 0; // continue until the user enters Q or until one of the types of people // overflows or until all 14 elements are taken up while (!type.equals("Q") &amp;&amp; (facultyCount &lt;= 3) &amp;&amp; (studentCount &lt;= 7) &amp;&amp; (employeeCount &lt;= 4) &amp;&amp; (index &lt; 14)) { if(type.equals("S") &amp;&amp; !type.equals("Q")) // Enter info for student { // Give the indexes the adresses people[index] = new Student(); sArray[studentCount] = new Student(); // Set the info personInfo(people[index]); studentInfo((Student)people[index]); System.out.println("\n"); // Increment the counts studentCount++; index++; } else if(type.equals("C") &amp;&amp; !type.equals("Q")) // Enter info for { // college employee // Give the indexes the adresses people[index] = new CollegeEmployee(); cArray[employeeCount] = new CollegeEmployee(); // Set the info personInfo(people[index]); employeeInfo((CollegeEmployee)people[index]); System.out.println("\n"); // Increment the counts employeeCount++; index++; } else if(type.equals("F") &amp;&amp; !type.equals("Q")) // enter info for faculty { // Give the indexes the adresses people[index] = new Faculty(); fArray[facultyCount] = new Faculty(); // Set the info personInfo(people[index]); employeeInfo((CollegeEmployee)people[index]); facultyInfo((Faculty)people[index]); System.out.println("\n"); // increment the counts facultyCount++; index++; } System.out.print("Please enter the next person type (S, C, F, " + "or Q): "); type = keyboard.next(); } // Displays error message then closes program if there was overflow if ((facultyCount &gt; 3) || (studentCount &gt; 7) || (employeeCount &gt; 4)) { System.out.println("Too much data for one type of person.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
