Я создал класс Address
, как показано ниже. Затем я хотел проверить равенство двух Address
es. Если все поля идентичны, два Address
es считаются идентичными.
Так, Я реализовал методы hashCode
и equals
.
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;
}
}
В TestCase для этого класса я попытался создать два идентичных адреса и вызвать assertEquals .. Однако это не удается ..
Класс AddressTests расширяет UnitTest {
@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);
}
}
Сбой assertEquals
Failure, expected: models.Address<#1000,South Avenue,null,null,New York,null,U.S,null> but was: models.Address<#1000,South Avenue,null,null,New York,null,U.S,null>
Может кто-нибудь помочь мне понять, почему это не удалось?
