An example of an AI chatbot conversation about Java constants and variables.
What is the difference between constants and variables in Java?
In Java, a variable is a container for storing data values that can change, while a constant is a fixed value that cannot be altered.
Can you give me an example of a constant in Java?
Sure! You can declare a constant in Java using the final keyword. For example: final int MAX_VALUE = 100; This means MAX_VALUE cannot be changed.
What happens if I try to change a constant?
If you try to change a constant, the compiler will throw an error, indicating that you cannot assign a new value to a final variable.
Are there any best practices for using constants in Java?
Yes! It's best to use uppercase letters for constant names and to group related constants in an interface or a class.
