问题描述

我来自php世界。你能解释一下getter和setter是什么，可以给你一些例子吗？

I'm from the php world. Could you explain what getters and setters are and could give you some examples?

推荐答案

这并不是真的需要教程。阅读封装

Tutorial is not really required for this. Read up on encapsulation

private String myField; //"private" means access to this is restricted

public String getMyField()
{
     //include validation, logic, logging or whatever you like here
    return this.myField;
}
public void setMyField(String value)
{
     //include more logic
     this.myField = value;
}
