Question on Assertions

[majohnad majohnad]

What will be the value of variable "totalParams" after line 7;if the following code is executed from command line as - java -ea AssertTest?
(Assume that the code is compiled and run with assertions enabled)

1.public class AssertTest
2.{
3.public static void main(String args[])
4.{
5.int count = args.length;
6.assert (Math.abs(count) == count);
7.int totalParams = count;
8.//more code
9.}
10.}
The Ans for the above question is given
It will throw an AssertionError at runtime at line 6, and statements after that line are not executed;hence value of totalParams can not be determined
I think this is wrong, it will print 0 as output.
kindly correct me If i am wrong..
Thanks in advance.

I ran it in my machine with no problems. I don't know why it should throw assertion error.

public class Test
{
public static void main(String args[])
{
int count = args.length;
assert (Math.abs(count) == count);
int totalParams = count;
//more code
}
}

I think this is wrong, it will print 0 as output.
I think is wrong too.. but why do you think it prints 0?

Hi Majohnad,
The args.length is 0,if you are not providing any command line arguments. Here Math.abs(count) == count returns true.
If the expression in the assert statement is true it won't throw any assertion error.
assert(Math.abs(count) == count) becomes assert(true). The control goes to next line. It prints 0, If you have System.out.println(totalParams).
