Answer 2

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.
