Answer:
Line E.
Explanation:
The given program is as follows:
public class Fishing {
byte b1 = 4; int i1 = 123456; long L1 = (long) i1; //Line A
short s2 = (short) i1; //Line B
byte b2 = (byte) i1; //Line C
int i2 = (int)123.456; //Line D
byte b3 = b1 + 7; //Line E
}
In the above code Line E will not compile and give following compilation error:
error: incompatible types: possible lossy conversion from int to byte
This error is coming because in Java b1 + 7 will be interpreted as int variable expression. Therefore in order to make code of Line E work the expression should be type casted as byte.
The correct code will be as follows:
public class Fishing {
byte b1 = 4; int i1 = 123456; long L1 = (long) i1; //Line A
short s2 = (short) i1; //Line B
byte b2 = (byte) i1; //Line C
int i2 = (int)123.456; //Line D
byte b3 = (byte)(b1 + 7); //Line E
}
