  2. False

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of strongly-typed languages.

Option A) True - This option is correct. Java is indeed a strongly-typed language. In strongly-typed languages like Java, each variable must be declared with its data type, and the type of a variable cannot be changed after it is declared. This strict type checking ensures that variables are used in a consistent and predictable manner.

Option B) False - This option is incorrect. Java is a strongly-typed language, as explained above.

The correct answer is A) True. Java is a strongly-typed language because it requires explicit declaration of variable types and enforces strict type checking.
