Solution
The false statement about abstract classes in Java is: "A class can inherit from multiple abstract classes."
In Java, a class cannot inherit from multiple abstract classes because Java does not support multiple inheritance. A class can only inherit from one parent class, whether it's abstract or not. However, a class can implement multiple interfaces.
