An example of an AI chatbot conversation about whether interfaces can have variables in Java.
Can interfaces have variables in Java?
In Java, interfaces cannot have instance variables, but they can have constants.
What do you mean by constants in interfaces?
Constants in interfaces are declared using the 'public static final' modifiers, and they are implicitly static and final.
Can you give me an example of a constant in an interface?
Sure! For example: public interface MyInterface { int CONSTANT_VALUE = 10; }.
Are there any restrictions on the types of variables in interfaces?
Yes, all variables in an interface must be public, static, and final, meaning they cannot be changed.
