import com.google.common.base.Objects; class Person { private String name; private int age; public int hashCode() { return Objects.hashCode(name, age); } }
import com.google.common.base.Objects; class Address { private String street; private String city; private String state; private String zip; public boolean equals(Object o) { if (o == null || !(o instanceof Address)) { return false; } Address other = (Address) o; return Objects.equal(street, other.street) && Objects.equal(city, other.city) && Objects.equal(state, other.state) && Objects.equal(zip, other.zip); } }In this example, the equals() method of the Address class uses the Objects.equal() method to compare the object to another object of the same type. The method returns true if all of the object's properties are equal to the other object's properties. Overall, the com.google.common.base.Objects package library provides convenient utility methods for working with objects in Java.
