Which of the following is not a valid way to declare a char variable in Java?
A. char x = 'A'
B. char y = 'n'
C. char z = 65
D. char w = 0x0041
Answer: Option D
Solution(By Examveda Team)
The correct answer is Option D: char w = 0x0041.In Java, Options A, B, and C are valid ways to declare a char variable, but Option D is not.
Here's the breakdown:
Option A: char x = 'A' - This is a valid way to declare a char variable in Java and initialize it with the character 'A'.
Option B: char y = 'n' - This is a valid way to declare a char variable in Java and initialize it with the character 'n'.
Option C: char z = 65 - This is a valid way to declare a char variable in Java and initialize it with the decimal value 65, which corresponds to the character 'A' in the Unicode character set.
Option D: char w = 0x0041 - This is not a valid way to declare a char variable in Java. It attempts to assign a hexadecimal value (0x0041) to a char variable, which is not allowed without type casting.
So, the correct options for declaring a char variable in Java are Options A, B, and C, while Option D is not valid.
