To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) java test - This option will not produce an AssertionError because the -ea
flag is not used to enable assertions.
Option B) java -ea test - This option will produce an AssertionError because the -ea
flag is used to enable assertions. The assertion on line 10 (assert a.length == 1;
) will fail if the length of a
is not equal to 1.
Option C) java test file1 - This option will not produce an AssertionError because the -ea
flag is not used to enable assertions.
Option D) java -ea test file1 - This option will not produce an AssertionError because the -ea
flag is used to enable assertions, but the program does not have any assertions to check.
Option E) java -ea test file1 file2 - This option will produce an AssertionError because the -ea
flag is used to enable assertions. The assertion on line 10 (assert a.length == 1;
) will fail if the length of a
is not equal to 1.
Option F) java -ea:test test file1 - This option will not produce an AssertionError because the -ea
flag is used to enable assertions, but the program does not have any assertions to check.
The correct answers are B and E. These options will produce an AssertionError because they include the -ea
flag to enable assertions, and the assertion on line 10 will fail if the length of a
is not equal to 1.
