happening in my if statement at the bottom, where it says "equals" is an error and "int cannot be dereferenced." Hope to get some assistance as I have no idea what to do. Thank you in advance! public class Catalog { private Item[] list; private int size; // Construct an empty catalog with the specified capacity. public Catalog(int max) { list = new Item[max]; size = 0; } // Insert a new item into the catalog. // Throw a CatalogFull exception if the catalog is full. public void insert(Item obj) throws CatalogFull { if (list.length == size) { throw new CatalogFull(); } list[size] = obj; ++size; } // Search the catalog for the item whose item number // is the parameter id.

Hello, I'm getting an "int cannot be dereferenced error" with my method. I'm trying to add two rational numbers (fractions) together and return the new rational number. From what I've read in my book and online, I've figured out that I can't invoked methods on primitives. But then how else would I get the numerator and denominator of the two rational numbers? Any help is greatly appreciated, thanks! Java Code: public RationalNumber add(RationalNumber other) { this.numerator = number.getNumerator() * other.getNumerator() + number.getDenominator() * other.getDenominator(); this.denominator = number.getDenominator() * other.getDenominator(); RationalNumber addedNumber = new RationalNumber(addNumerator, addDenominator); return addedNumber; } Reply With Quote 12-14-2011,08:43 AM #2 pbrockway2 Moderator Join Date Feb 2009 Location New Zealand Posts 4,712 Rep Power 14 Re: How to solve "int cannot be dereferenced" error? how else would I get the numerator and denominator of the two rational numbers? Quite possibly with .numerator and .denominator as you are already doing with "this". But that's only a guess. For better, post the Rational class so we can see how it's defined. And the full and exact compiler message. Also say precisely what this method is supposed to do. At the moment you have it doing two things: creating and return a new Rational, and also altering the state of "this". ----- Also you might want to check your formula. a/b +c/d != (ac+bd)/bd Reply With Quote « error when adding actionlistener | data type validation » Similar Threads How To Solve "Too Many Connections" error message By ahmed30 in forum JDBC Replies: 2 Last Post: 01-24-2011, 01:2
