Our professor has given us exercises, and given us the code how they should've been done, so there's something I don't get, I have sent him an email a week ago, but he didn't reply, so I'm turning to stackoverflow, where I don't get is in the comments:
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;
}
}
In the exercise it said to 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, and offer a method that represents a string in an object of 'Futbollisti' class in the format: 'emri : mosha - pozita'
And, to offer a method for comparing 2 objects of Futbollsti, which all were done, but I don't know if he should've left out the 'emri'. So is the code correct or did he make a mistake?
Setter methods are omitted if the developer wants to make a field read-only.
By the description of your requirements:
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
it's not likely a read-only field, so he made a mistake by forgetting the setter.
