I am new to Java and I have failed to find anything about this case.
I am basically trying to pass this array called vakken to a new class called Vak , Vak expects to receive a String and a int.
Vak[] vakken = new Vak[1];
vakken[0] = new Vak("Test",3);
Vak vak = new Vak(vakken[0]);
Whenever I try the code above I get this error.
Exception in thread "main" java.lang.UnsupportedOperationException: Not supported yet.
at ectsmonitor2.Vak.<init>(Vak.java:24)
at ectsmonitor2.ECTSmonitor2.main(ECTSmonitor2.java:27)
Java Result: 1
Vak.class
public class Vak {
public String naam;
public int teVerdienenEcts;
public Vak(String vakNaam, int vakTeVerdienenEcts){
naam = vakNaam;
teVerdienenEcts = vakTeVerdienenEcts;
}
}
You haven't actually coded your constructor that takes a Vak
yet, you made it throw UnsupportedOperationException
. Put some code in the constructor eg
public Vak(Vak v) {
this(v.naam, v.teVerdienenEcts);
}
This line wont work for sure
Vak vak = new Vak(vakken[0]);//IDE will display error message here
Because you have no such constructor for this.
Create a new constructor that takes an object of its own type.
Similar to this:
public Vak(Vak anObject){
//do stuffs here
}
These type of constructors are called copy constructors
And generally you won't want your attributes to be public . Make them private .
