Can someone help me and complete this simple polynomial program(can be demonstrated using linked lists);

public class Polynomial {
/* Constructs a new polynomial of degree zero */
public Polynomial() {
}

/* Returns an integer representing the coefficient
* of the x^power term
*/
int getCoefficients(int power) {
}

/* Sets the coefficient of the x^power term to coef. */
void setCoefficients(int coef, int power) {
}

/* Returns the String representation of the polynomial.
* For example, a polynomial can be represented as either
* 3 * x^2 + 2 * x + 1 or
* 3x^2 + 2x + 1
* Any term whose coefficient is zero should not appear
* in the string unless the polynomial has only a single
* constant term of zero.
*/
public String toString() {
}

/* Evaluates the polynomial for the value x and returns
* the result p(x).
*/
double evaluate(double x) {
}

/* Add to this polynomial the polynomial "other" and
* return the resulting polynomial.
*/
}
}

Exactly the correct answer for a "Please do my homework for me" request.

This is homework. You should write the code. You'll learn better that way.

A hint to help you get started: Consider the relationship between int power and the LinkedList index. Doing this might inspire a really good idea.

Why do not u use array? thaz much easier.....

Because you don't know in advance how many entries will be needed. The implementations of 'java.lang.List' let you add entries at runtime very easily. Personally, I would favor ArrayList for this assignment. But linked lists were mentioned, so maybe the instructor expects LinkedList.
