A Java Bean is just a simple class that implements the serializable interface has only a default or no argument constructor, has properties that may or may not be changed (i.e. read-write, read-only, write-only), its methods are just getters and setters and begin with get, set, or is. Example: package com.sololearn; public class PersonBean implements java.io.Serializable { private String firstName = null; private String lastName = null; private int age = 0; private int height = 0; private boolean married = false; public PersonBean() { } public String getFirstName(){ return firstName; } public String getLastName(){ return lastName; } public int getAge(){ return age; } public int getHeight() { return height; } public boolean isMarried() { return married; } public void setFirstName(String firstName){ this.firstName = firstName; } public void setLastName(String lastName){ this.lastName = lastName; } public void setAge(Integer age){ this.age = age; } public void setHeight(Integer height) { this.height = height; } public void setMarried(boolean married) { this.married = married; } } Java Beans are used to get, store, save (serializable), and transfer data. They are highly reusable from one project to the next.
