Answer: Option A
Solution
Answer: Option A
Solution:
The correct answer is Option A: 0.In Java, if an int variable is not explicitly initialized, it will be assigned the default value of 0.
This default value is used when no initial value is provided for an integer variable.
Option B, Option C, and Option D are not the default values for an uninitialized int variable in Java.
