Which of the following is the correct way to declare a byte variable named myByte and initialize it to 5 in Java?
A. byte myByte = 5
B. byte myByte = "5"
C. byte myByte = '5'
D. byte myByte = 5.0
Answer: Option A
Solution(By Examveda Team)
The correct answer is Option A: byte myByte = 5.In Java, the correct way to declare a byte variable named myByte and initialize it to the integer value 5 is by using Option A.
Here's the breakdown:
Option A: byte myByte = 5 - This is the correct way to declare a byte variable in Java and initialize it to the integer value 5.
Option B: byte myByte = "5" - This is not a valid way to declare a byte variable because it attempts to assign a String value ("5") to a byte variable, which is not allowed without type casting.
Option C: byte myByte = '5' - This is not a valid way to declare a byte variable because it attempts to assign a character ('5') to a byte variable, which is not the same as an integer value.
Option D: byte myByte = 5.0 - This is not a valid way to declare a byte variable because it attempts to assign a double value (5.0) to a byte variable without type casting.
So, the correct way to declare a byte variable named myByte and initialize it to 5 in Java is byte myByte = 5.
