Question: 1 / 400

Which of the following statements is correct about constants?

Constants are written using uppercase letters because the compiler ignores constants declared in lowercase letters.

The data stored inside a final variable can be changed using an assignment statement.

You can make a variable constant by using the constant reserved word while declaring the variable.

Variables defined using final make a code snippet more readable and easier to maintain.

The statement about defining variables using the final keyword indeed highlights an important aspect of programming that promotes code clarity and maintainability. When a variable is declared as final, it signifies that its value cannot be changed once initialized. This helps convey the programmer's intent that the variable should remain constant throughout its scope, making it apparent to anyone reading the code that certain values are meant to remain unchanged.

This practice of using final variables contributes to better readability, as developers can quickly identify which values are fixed and which may change. Additionally, this can prevent accidental modifications of important values, reducing the potential for bugs and making the code easier to understand and maintain over time. Overall, utilizing final for constants allows for clearer signaling of the variable's purpose and enhances the overall organization of the code.
