Can We Create an Object of a Final Class in Java?

No, you cannot create an object of a final class in Java.

Here's why:

• Final Classes are Immutable: When a class is declared as final, it becomes immutable. This means you cannot extend or inherit from it.
• No Subclasses: Since you cannot create subclasses of a final class, you cannot create objects of a final class using the new keyword.

Example:

final class MyFinalClass {
    // Class definition
}

// This will result in a compile-time error:
MyFinalClass obj = new MyFinalClass(); 

Practical Insight:

Final classes are often used to prevent accidental modification or extension of a class. This ensures the integrity and consistency of the class's behavior.

Example Use Cases:

• String Class: The String class in Java is final to prevent modification of its internal representation.
• Math Class: The Math class is final to ensure its mathematical functions remain consistent and reliable.
