Explain use of final and super keywords in Java.

### The `final` Keyword:

In Java, the `final` keyword is used to restrict the functionality of a class, method, or variable. Once a class is declared as `final`, it cannot be subclassed, meaning no other class can extend it. When applied to a method, the `final` keyword indicates that the method cannot be overridden by subclasses. Finally, when used with a variable, it means the variable is a constant and cannot be reassigned after its initial assignment.

#### 1. Final Classes:

```java
final class Example {
    // Class implementation
}
```

In this example, the class "Example" is declared as final, and no other class can extend it.

#### 2. Final Methods:

```java
class Parent {
    final void display() {
