I saw couple of similar questions but still cannot figure out my own case. Here is the complete codes: package inclass; class OneInt { int n; http://stackoverflow.com/questions/15857377/new-to-java-and-have-the-error-int-cannot-be-dereferenced OneInt(int n) { this.n = n; } @Override public boolean equals(Object that) { if (that instanceof OneInt) { OneInt thatInt = (OneInt) that; return n.equals(thatInt.n); // error happens here } else { return false; } } public static void main(String[] args) { Object c = new OneInt(9); Object c2 = new OneInt(9); System.out.println(c.equals(c2)); System.out.println(c.equals("doesn't work")); } } Thank you very much for helping me with this little trouble. java share|improve this question edited Apr 7 '13 at 0:08 paulsm4 57.5k67192 asked Apr 7 '13 at 0:04 Tian 3313 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted equals is a method of a class. int is a primitive, not a class.
