Question

what is the Technical meaning of this context plain-vanilla Java Beans & plain-vanilla Java Class ??.

Answer 1

A ‘plain-vanilla’ bean/class means a very basic class usually with the following properties;

• Doesn’t extend or implement anything
• Has private class variables
• Has an empty constructor
• Has standard getter/setter methods

This is also called a POJO (Plain Old Java Object). For example;

public class MyPojo
{
    /*
     * Private class variables
     */
    private String name;
    private int size;

    /**
     * Empty constructor
     */
    public MyPojo()
    {
    }

    /*
     * Standard getter/setters 
     */
    public String getName()
    {
        return name;
    }

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

    public int getSize()
    {
        return size;
    }

    public void setSize(int size)
    {
        this.size = size;
    }   
}
