Question

i have a base class, a child class, an interface, and a child class that implements this interface

-base Abstract class Seq

public abstract class Seq {...some functions...}

-class For extends Seq

public class For extends Seq{
    int first, last, step;
    public For( int a, int b, int c)
      {...some work on a,b,c }
}

till now, everthing is perfectly fine! i tested it.

public interface SeqIt {
    public boolean function1();
    public int function2();
}

-class ForIt that implements SeqIt (the interface)
the problem is the child class constructor

public class ForIt implements SeqIt{
      public void ForIt( For x ) //here is the problem//
              {...the work i wanna do...}
          }

i have to call it from the main using this statement ForIt fi = new ForIt(new For(3, 8, 2));

so how should i write the constructor?

Answer 1

Your question isn’t very clear, but it looks like your problem is that you have void in your constructor signature.

What you want is:

public ForIt( ... )
