What's that mean by faulty program in java? I am told that it is any wrong in calculation for numerical program. Really appreciate if someone could give examples here to clarify about this topic.
Thanks in advance

A faulty program would compile and run without throwing any exceptions but would give the wrong result in some cases. A program designed to calculate the factorial of a number would be faulty if it gave say, 0 for the factorial of 0, even if it gives correct results for the other positive integers.

How about this:
original program: a > b
to get it fault, you change to b < a
After run, we get different result so we know that there is code error in the program. Is that so..?
thanks for the explanation.
Alright then one more question regarding this please, from your experience is there any example of complete numerical java program (open source)?
so from that I could learn to create/extract many faults.....

Depends on what you mean by "complete numerical". Any program that uses a numerical type could be deemed numerical. You can write a program for solving a quadratic equation and play around with it or one to do a cubic spline e.t.c you can find lots of such programs on the internet. My bet is that it will be more fun if you write one yourself.

complete here means - complete java program from open source which i can exctract many2 faults from it. and yeah as what you've said any program uses a numerical we can play with it...right. shall work on it.many thanks to you.
have a nice day!
friends,
I do need confirmation about my java program. Please refer code below to see my question: - public ComplexNumber multDouble(double m)
-
{
-
ComplexNumber multDouble = new ComplexNumber(a,b);
-
a=m*a; //is this statement involves with two executions?
-
b=m*b; // ''
-
-
return multDouble;
-
}
My lecturer was mentioning about focus on two executions in numerical java program. Please share few words...thanks.

What do you mean by two executions?
What do you mean by two executions?
a = m * a
variable 'm' - one execution and 'a' one execution.
so to get them fault, I could change like a= m/a have you heard something like this before?
hope someone could help me to get a clear picture about:
What is 'real life java program/software' ? is that something about to solve real problems?
If there is an example of this program please share with me...perhaps computation prog.
Really appreciate any efforts made to answer my this question.
thanks

A complete java program? That would be my guess for a 'real life java program' - one that can compile and run in a JVM.

Really..okay..
I've heard my lecturer say is something like graph theory.

Taken out of context, i can only offer my best guess - you should talk to your professor and figure out if he's talking about a specific project he is working on (ie, RealLife Program), or if there is something else that is missing (ie, "analysis of real life program").
Of course, it's also possible one of the other people here have heard of it. Anyone?

thank you Sicarie. Really appreciate your say :)
that's why, i was hearing something like java programs
that solve real problems.

No worries mate.

Basically all programming laguages can solve some real life problems. With Java it is easy to model a real life situation by making use of object oriented programming principles.

Yes, that's right.
I read in few articles some examples of real like programs are from SourceForge - such BooleanExpression or Commons.Math - Apache Jakarta & etc...
