What is the default access modifier for a class in Java/C#?
Difficulty: 2/10
Default Class Accessibility
The answer differs between Java and C#. In Java, a top-level class with no modifier has package-private accessibility, meaning it is accessible only within the same package. A nested Java class follows member access rules. In C#, a top-level class defaults to internal accessibility, while a nested class defaults to private when no access modifier is specified. This distinction is important when designing module and assembly boundaries.
