Answer
To share code among related classes. Frame the concept in practical terms so you can explain it during interview discussion.
An abstract class can provide default behavior using implemented methods, whereas an interface cannot. This is useful when related classes share common code. For instance, an abstract class 'ElectronicProduct' can have implemented methods like 'powerOn()' that are common across all electronic products, reducing code duplication compared to using only interfaces.
