10 What modifiers would be legal at XX in the following code? public class MyClass1 { public static void main(String argv[]){ } /*Modifier at XX */ class MyInner {} }
-
a. public
-
b. private
-
c. static
-
d. friend
For inner classes (non-static nested classes), the modifiers public and private are legal at the class level within an outer class. However, 'static' is NOT legal for a non-static inner class - to make it static, it must be explicitly declared as a 'static nested class' with different syntax. The 'friend' keyword doesn't exist in Java.
To determine which modifiers would be legal at XX in the given code, let's go through each option:
Option A) Public - This option is correct because the "public" modifier can be used for nested classes. It allows the class to be accessed from any other class.
Option B) Private - This option is correct because the "private" modifier can also be used for nested classes. It restricts the visibility of the class to only within the enclosing class.
Option C) Static - This option is incorrect because the "static" modifier cannot be used for nested classes. It can only be used for top-level classes, interfaces, and inner interfaces.
Option D) Friend - This option is incorrect because the "friend" modifier does not exist in Java. It is a modifier used in other programming languages like C++.
Therefore, the correct modifiers that would be legal at XX in the given code are A) Public and B) Private.
