Question

Will the following statement sequence compile? If not which line causes the compile error? The line numbers are just for reference. _________ int i; int j = i; j = 3; ________ Select one:

a. yes
b. no, line 3
c. no, line 1
d. no, line 2

Answer 1

The statement sequence will not compile due to an error on line 2 where an uninitialized variable 'i' is used to initialize another variable 'j'.

Step-by-step explanation:

The student asked whether the statement sequence would compile, and if not, which line would cause the compile error.

The answer is d. no, line 2. In line 1, the variable i is declared but not initialized; it's a compilation error to use an uninitialized local variable in Java. In line 2, the variable j is being initialized with the value of i. Since i is not initialized, this line will result in a compile-time error.

Line 3, which assigns the value 3 to variable j, is correct and would not cause an error if the previous lines were correct.
