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.
