What is the minimum and maximum number of abstract classes a class can inherit from in Java?

In Java, a class can only inherit from one class, whether abstract or concrete. That is:

• Minimum number of abstract classes for inheritance — 0 (if the class inherits from a concrete class or from Object).
• Maximum number — 1, since multiple inheritance of classes is not supported in Java.

However, a class can implement multiple interfaces, including interfaces with abstract methods, which allows achieving functionality similar to multiple inheritance.
