java - getter 和 setter 如何工作？

Question

我来自 php 世界。您能否解释一下 getter 和 setter 是什么，并举一些例子？

Answer 1

这实际上并不需要教程。阅读encapsulation

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

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;
}
