    copied!<p>I created an <code>Address</code> class like below,Then I wanted to check equality of two <code>Address</code>es.If all the fields are identical,the two <code>Address</code>es are considered identical.</p> <p>So,I implemented the <code>hashCode</code> and <code>equals</code> methods.</p> <pre><code>public class Address{ public String addressLine1; public String addressLine2; public String city; public String state; public String pincode; public String phoneNumber; public String country; public Address() { } public Address(String addressLine1, String addressLine2, String city, String state, String pincode, String phoneNumber, String country) { this.addressLine1 = addressLine1; this.addressLine2 = addressLine2; this.city = city; this.state = state; this.pincode = pincode; this.phoneNumber = phoneNumber; this.country = country; } @Override public int hashCode() { final int prime = 31; int result = super.hashCode(); result = prime * result + ((addressLine1 == null) ? 0 : addressLine1.hashCode()); result = prime * result + ((addressLine2 == null) ? 0 : addressLine2.hashCode()); result = prime * result + ((city == null) ? 0 : city.hashCode()); result = prime * result + ((country == null) ? 0 : country.hashCode()); result = prime * result + ((phoneNumber == null) ? 0 : phoneNumber.hashCode()); result = prime * result + ((pincode == null) ? 0 : pincode.hashCode()); result = prime * result + ((state == null) ? 0 : state.hashCode()); return result; } @Override public boolean equals(Object obj) { System.out.println("equals("+obj); if (this == obj) return true; if (!super.equals(obj)) return false; if (getClass() != obj.getClass()) return false; Address other = (Address) obj; if (addressLine1 == null) { if (other.addressLine1 != null) return false; } else if (!addressLine1.equals(other.addressLine1)) return false; if (addressLine2 == null) { if (other.addressLine2 != null) return false; } else if (!addressLine2.equals(other.addressLine2)) return false; if (city == null) { if (other.city != null) return false; } else if (!city.equals(other.city)) return false; if (country == null) { if (other.country != null) return false; } else if (!country.equals(other.country)) return false; if (phoneNumber == null) { if (other.phoneNumber != null) return false; } else if (!phoneNumber.equals(other.phoneNumber)) return false; if (pincode == null) { if (other.pincode != null) return false; } else if (!pincode.equals(other.pincode)) return false; if (state == null) { if (other.state != null) return false; } else if (!state.equals(other.state)) return false; return true; } public String toString() { return this.addressLine1+","+this.addressLine2+","+this.city+","+this.state+","+this.pincode+","+this.country+","+this.phoneNumber; } } </code></pre> <p>In the TestCase for this class ,I tried to create two identical addresses and calls assertEquals..This fails however..</p> <p>class AddressTests extends UnitTest {</p> <pre><code>@Test public void testAddressEquality() { Address address1 = new Address(); address1.addressLine1 = "#1000,South Avenue"; address1.state = "New York"; address1.country = "U.S"; System.out.println("address1="+address1); Address address2 = new Address(); address2.addressLine1 = "#1000,South Avenue"; address2.state = "New York"; address2.country = "U.S"; System.out.println("address2="+address2); assertEquals(address1,address2); } </code></pre> <p>}</p> <p>assertEquals fails </p> <pre><code>Failure, expected: models.Address&lt;#1000,South Avenue,null,null,New York,null,U.S,null&gt; but was: models.Address&lt;#1000,South Avenue,null,null,New York,null,U.S,null&gt; </code></pre> <p>Can someone help me understand why this failed?</p>
