To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) compiletime error at lines 1,2,3,4,5 - This option is incorrect. It suggests that there are compile-time errors at all the given lines, which is not true.
Option B) compiletime error at lines 2,3,4,5 - This option is correct. There are compile-time errors at lines 2, 3, 4, and 5.
Option C) compiletime error at lines 2,3,4 - This option is incorrect. It suggests that there are compile-time errors at lines 2, 3, and 4, but not line 5.
Option D) No error - This option is incorrect. There are indeed compile-time errors in the code.
Now, let's analyze the code:
- The code declares a class
C
with a public integer variable i
.
- Inside the
main
method, there is a declaration of a local integer variable i
. This variable declaration shadows the class variable i
. This is allowed, but it can lead to confusion. However, there is no compile-time error at this line.
- The code declares a private integer variable
a
and initializes it with the value 1. This is allowed, and there is no compile-time error at this line.
- The code declares a protected integer variable
b
and initializes it with the value 1. This is allowed, and there is no compile-time error at this line.
- The code declares a public integer variable
c
and initializes it with the value 1. This is allowed, and there is no compile-time error at this line.
- The code tries to print the sum of
a
, b
, and c
. However, this line is outside any method, which is not allowed in Java. This leads to a compile-time error.
The correct answer is B) compiletime error at lines 2,3,4,5. This option correctly identifies the lines with compile-time errors.
