Non ``++final++`` classes shouldn't use a hardcoded class name in the ``++equals++`` method. Doing so breaks the method for subclasses. Instead, make the comparison dynamic.
== Noncompliant Code Example
----
public class Fruit {
private Season ripe;
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (Fruit.class == obj.class) { // Noncompliant
return false;
}
// ...
----
== Compliant Solution
----
public class Fruit {
private Season ripe;
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (this.class == obj.class) { // will work for subclasses too
