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

推荐答案

教程并不是真正需要的.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 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;
}
