Compiling errors and return methods

Question

The error is invalid method declaration; return type required
public Term(double c, int d)
Thanks
public Term(double c, int d)
      coeff = c;
      degree = d;
      Multiplies a term.
      @param other the other term
      @return the new term after mulitiplication
   public Term multiply(Term other)
      return new Term(coeff * other.coeff, degree + other.degree);
      Adds a coefficient.
      @param c the coefficient to add
   public void add(double c)
      coeff += c;
      return c;
      Gets the coefficient.
      @return the coefficient
   public double getCoeff()
      return coeff;
      Gets the degree.
      @return the degree
   public int getDegree()
      return degree;
   private double coeff;
   private int degree;
}

Answer 1

I bet this means your enclosing class isn't called Term
is there an enclosing class at all ? what are those two declarations at the end ? member variables ?
When posting code, take care that the curly braces match, please (ie dont post half blocks of code)
