What is the minimum value that can be stored in a char variable in Java?
A. 0
B. -128
C. -32768
D. 'a'
Answer: Option A
Solution(By Examveda Team)
The correct answer is Option A: 0.In Java, a char variable is a 16-bit unsigned data type that can represent Unicode characters. The minimum value that can be stored in a char variable is 0, which corresponds to the Unicode character with the code point of zero.
Here's the breakdown:
Option A: 0 - This is the correct minimum value that can be stored in a char variable in Java. It represents the Unicode character with the code point of zero.
Option B: -128 - This value is not applicable to char variables in Java. It's more relevant to signed integer types.
Option C: -32768 - This value is not applicable to char variables. It's a range associated with short or int data types in Java.
Option D: 'a' - This represents the character 'a', not a numeric value, and it is not the minimum value that can be stored in a char variable.
So, the correct minimum value that can be stored in a char variable in Java is 0
