    <p>Fundamental question, and I've tried to apply several other related questions to figure it out, but this always comes back as null.</p> <pre><code>public class Consultant { public Name name; String lastName; String firstName; String middleName; public Consultant (Name name){ this.name = name; this.lastName = name.getLastName(); this.firstName = name.getFirstName(); this.middleName = name.getMiddleName(); } public Name getName(){ return name; } public void setFirstName(){ firstName = name.getFirstName(); } public void setMiddleName(){ middleName = name.getMiddleName(); } public void setLastName(){ lastName = name.getLastName(); } @Override public String toString(){ return lastName + ", " + firstName + " " + middleName; } </code></pre> <p>}</p> <p>Why I try to use this anywhere as a print out, all I see is null, null null. I've tried adjusting the code several times to no avail. </p> <p>Here is the test class snippet that runs successfully, just returns null values for the name:</p> <pre><code>public void consultantTimeToStringTest() { String fName = "Test"; String lName = "Dude"; Name contact = new Name(lName, fName); Consultant testConsultant = new Consultant(contact); System.out.println(testConsultant.toString()); </code></pre> <p>Here is the Name class as well:</p> <pre><code>public class Name { private String firstName; private String middleName; private String lastName; public Name(){ } public Name(String lastName, String firstName){ } public Name(String lastName, String firstName, String middleName){ this.firstName = firstName; this.middleName = middleName; this.lastName = lastName; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Name other = (Name) obj; if (firstName == null) { if (other.firstName != null) return false; } else if (!firstName.equals(other.firstName)) return false; if (lastName == null) { if (other.lastName != null) return false; } else if (!lastName.equals(other.lastName)) return false; if (middleName == null) { if (other.middleName != null) return false; } else if (!middleName.equals(other.middleName)) return false; return true; } public String getFirstName(){ return firstName; } public String getLastName(){ return lastName; } public String getMiddleName(){ return middleName; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((firstName == null) ? 0 : firstName.hashCode()); result = prime * result + ((lastName == null) ? 0 : lastName.hashCode()); result = prime * result + ((middleName == null) ? 0 : middleName.hashCode()); return result; } public void setFirstName(String firstName){ } public void setLastName(String lastName){ } public void setMiddleName(String middleName){ } public String toString(){ StringBuilder result = new StringBuilder(); String NEW_LINE = System.getProperty("line.separator"); result.append(lastName); return result.toString(); } </code></pre> <p>}</p>

    1. COWhere are you assigning values to firstName,middleName and lastName? if you don't assign anything by default string fields will be null.

    2. COTangentially, why are you duplicating state? The "set" methods are particularly confusing as they just do what the constructor has already done.

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.
