本文介绍如何在MyEclipse中为类属性自动生成Getter和Setter方法，并探讨了这些方法在数据封装中的作用。Getter和Setter不仅有助于隐藏内部状态，还能用于验证数据、维护对象完整性以及格式化输出。

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

In MyEclipse, you can just generate setter and getter by:

choose the parameter defined -> source -> generate getter and setter

The getter and setter methods can help hide internal state and requiring all interaction to be performed through an object's methods is known as data encapsulation — a fundamental principle of object-oriented programming.

In fact:

Your object uses setter to:

restrict and validate data passed to the setter
hide its inner data structure (other object are interested by a service not how the service is built, this can also include optimisation)
preserve its integrity in every state (changing other fields if required)

it will use getter to

format data in output as desired by the client
control a sequence of services (for instance it will provide data if and only if a connection has been established)
