Final answer:
The statement is false; getters in the JavaBeans convention must have a non-void return type that matches the property they access.
Step-by-step explanation:
The statement that getters that comply with the JavaBeans convention are always declared with a void return type is false. In fact, getters in the JavaBeans convention are methods that are used to retrieve the value of a property. They must have a non-void return type that matches the type of the property they are accessing and should start with the prefix 'get' followed by the property name with the first letter capitalized.
For example, if there is a property named 'age', the corresponding getter method should be named 'getAge' and return an integer if 'age' is an integer. Getters allow the internal state of an object to be accessed in a controlled manner.
