When a class inherits from another class, the class name of the child class contains the class name of the parent class. For example:

<code class="java">class Child extends Parent {
    // ...
}</code>

When a class implements an interface, the implements keyword will be added after the class name, followed by The name of the interface. For example:

<code class="java">class Employee implements Comparable<Employee> {
    // ...
}</code>
