Solution

Answer

The statement is True.

Explanation:

In Java, when an interface extends multiple interfaces, it can inherit the abstract methods from all parent interfaces. In the provided code:

  1. Interface A declares a method aMethod().
  2. Interface B declares a method bMethod().
  3. Interface C extends both A and B, which means C inherits both aMethod() and bMethod().
  4. Additionally, C has its own method cMethod().

This is a valid way to define interfaces in Java, allowing for multiple inheritance of method signatures. Thus, the program as described is correct.

This problem has been solved
