    <p>consider the below class</p> <pre><code>public class Player { private int id; public int getId() { return id; } public void setId(int id) { this.id = id; } } </code></pre> <p>Assume there is another class in the same package </p> <pre><code>public class Sample { Player p1 = new Player(); Player p2 = new Player(); Player p3 = new Player(); Player p4 = new Player(); //p1. } </code></pre> <p>In this Class accessing the methods p1.setId(int) is not possible unless it is called in side another method </p> <pre><code>public class Sample { Player p1 = new Player(); Player p2 = new Player(); Player p3 = new Player(); Player p4 = new Player(); void example () { int x; p1.setId(x); } } </code></pre> <p>Inside example p1.setId() is possible . I understand that java is enabling the access of methods only inside another method. So its more secure. But I want to make clarification as why such restriction is there and what concept data abstraction or Encapsulation is shown with this restriction. Thanks in advance .</p>

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.
