我的教授在setter中跳过了一个变量,他写的代码有错吗?

My professor skiped a variable in the setter, did he make a mistake in the code he wrote?

我们的教授给了我们练习,给了我们应该如何完成的代码,所以有些东西我不明白,我一周前给他发了一封电子邮件,但他没有回复,所以我转向 Whosebug,我没有在评论中得到:

public class Futbollisti {

private String emri, pozita;
private int mosha;

public Futbollisti(String e, String p, int m){
    emri = e;
    pozita = p;
    mosha = m;

}
public String getEmri(){
    return emri;

}
public String getPozita(){
    return pozita;
}
public int getMosha(){
    return mosha;
}
public void setPozita(String p){ /*right about here, why did he skip the 
'emri', he went straight to pozita, but didn't set emri, did he do a 
mistake? */
    pozita = p;

}
public void setMosha(int m){
    mosha = m;
}
public String toString(){
    return emri + " : " + mosha + " - " + pozita;

}
public boolean equals(Object obj){
    if(obj instanceof Futbollisti){
    Futbollisti f = (Futbollisti) obj;
        return emri.equals(f.getEmri())
                && pozita.equals(f.getPozita())
                && mosha == f.getMosha();

}
    return false;
}
}

在练习中它说要创建一个接受这些变量(emri, pozita, mosha)的构造函数,并初始化它们,然后为所需的属性提供 get 和 set 方法,并提供一个表示'Futbollisti' class 对象中的字符串,格式为:'emri : mosha - pozita' 并且,提供一种比较 Futbollsti 的 2 个对象的方法,这些都已完成,但我不知道他是否应该遗漏 'emri'。那么代码是正确的还是他弄错了?

Setter 如果开发人员想要将字段设置为只读,则省略方法。

根据您的需求描述:

make a constructor that accepts those variables (the emri, pozita, mosha), and initialize them, then offer the get and set methods for the attributes needed

这不太可能是只读字段,所以他忘记了 setter。
