An example of an AI chatbot conversation about Java method return types.
What are the different return types in Java methods?
In Java, methods can return various types, including primitive types (like int, double), objects, and void.
Can you explain what 'void' means in this context?
'Void' means that the method does not return any value. It's used when you only want to perform an action.
What about returning objects? Can you give an example?
Sure! For example, a method can return a String object like this: public String getName() { return "John"; }.
Are there any restrictions on what a method can return?
Yes, a method can only return a type that matches its declared return type. If it declares to return an int, it can't return a String.
