Question
What will be the error in the following Java code? byte ct = 67; ct = ct * 67;Options* operator has converted ct * 67 into int, which can not be converted to byte without castingct cannot contain value 100, limited by its rangect cannot contain value 67No error in this code
Solution
The error in the given Java code is that the * operator has converted ct * 67 into int, which cannot be converted to byte without casting.
Here's why:
In Java, when you perform a mathematical operation, the result is automatically upcasted to int if the operands are byte, short, or int. This is called type promotion.
In the given code, ct is a byte and 67 is an int. When you multiply them, the result is an int. However, you're trying to assign this int result back to a byte variable (ct). This is not allowed in Java without explicit casting.
So, to fix the error, you need to cast the result back to byte:
byte ct = 67;
ct = (byte) (ct * 67);
This will tell the compiler to treat the result as a byte, not an int.
