在Java中创建对象和数组

Question

Hi guys I was wondering if you could shed some light on and idea I was thinking of for my current project. I looking to create say and array of terms, where terms contains two or three values/variables.

Let me try to clear this up as best I can right now.

class Term(double e,double c){
      coeff=c;  
      exp=e;
  }

Polynomial poly1[]=[degree]//where degree is some make value of polynomial
poly1[0]= new Term(1,2);

i would also like to know if i would be able to call the values of the Term in the poly1 later like:

poly1[0].getExp
//where this would give me the exp value of 
//Term in the first entry in the poly1 array

sorry if doesn't make much sense. Just let me know and I'll try to clear it up.

Thanks ahead of time.

Answer 1

I think this is basic OOP problem: Polynomial should be parent class of Term (or Polynomial is an interface)

interface Polynomial {
   double getExp();
}

class Term implements Polynomial {
   private double coeff;
   private double exp;
   public Term (double e,double c){
      coeff=c;  exp=e;
   }
   @overide
   public double getExp(){
      return exp;
   }
}
