There are key differences between an ArrayList and an Array. You are trying to find the length of an ArrayList, not an array. You are looking for med.size() not med.length

I am asked to copy an array and return a deep copy of the idx index, this is what i did but told i am still not copying the array. I have no idea what to do.
public static int[][] getOrder(int idx) {
int[][] product = null;
int noOrders;
if (idx >= 0 && idx < ORDERS.length) {
for (noOrders = 0; noOrders < ORDERS.length; noOrders++) {
if (noOrders == idx) {
product = ORDERS[noOrders].clone();
}
}
} else {
System.err.println("idx: " + idx + " is not valid!");
return null;
}
return product;
}
}

Am new in Java and l have an issue which l urgently need a help. But let me explain in detail so that my question could be understood.
First of all, there is a domain and there is also a PC with windows server 2012 which have an Active directory. And through this Active Directory, all other PCs in the domain can be seen.
Now, l was given a project which l need to develop a programme that have to access files and folders in each PC seen in the Active Directory.
How can l achieve that? Which lib or API do l use. l need any idea to achieve that.
l have used the DirContext in JNDI API, still l don't get.
l need help in that. Thanks

Hello;
I'm beginner in java ; I want to implement the ACO algorithme for solving a problem of shortest path (minimize the time of target) in java and I don't know where I should start.
Please I need a help if you have.
thanks;

Start with something simpler. You say you are a beginner, so what have you actually learned up to now? Have you worked through all the tutorials at The Java™ Tutorials[^]?

Thank you for your answer;
yes,I read a lot of toturials for java and I win to implement an interface for writing the informations of my subject(departure and arrival hours of vehicle and their price ; target time...) in a file .txt
and reading them .
now I need to know how can adapt the ant colony system for this problem? what is the steps?
thank you in advance.

1. Research the subject.
2. Create a design for your program (GUI or Text based)
3. Code and Test.

I'm in last step"code and test" and I have a problem in this step exactly.
I implement the graph (nodes "cities"; arcs"line of the mode of transport" and the modes of transport )
now I search to know how can implement the algorithm of ant colony system for calculate the minimum times for a travel from a node source to a node destiation ?
Thank you for your help.

Implementing an algorithm is merely writing the code to do the calculations. I do not know this algorithm so cannot offer any suggestions.

Hi all,
I am trying to execute javascript in a PDF that will allow the form to be submitted via email with a subject line that will pull a value from a field in the form. I am able to get the email portion to work, but I have not been able to customize the subject line to pull from the field. Below is the base script I am using to send the email without the customized subject line:
this.submitForm({
cURL: "mailto:aamos@lrrc.com?subject=TSC Form&body=",
cSubmitAs: "PDF"
});
The field I am wanting to pull from is labeled "Name". Below was one of my attempts, all of which have not worked.
Failed Script:
this.submitForm({
var Name = this.getField("Name").value;
cURL: "mailto:aamos@lrrc.com?subject=TSC Form (Name)&body= ) ",
cSubmitAs: "PDF"
});
Can some one point me in the right direction or help me with where I went wrong in the script? I am new to this, and glad I was able to execute the first script successfully but I feel I am in over my head with the customization.
Thanks in advance your your assistance.

UPDATE data SET
full_name = "SARA",
reg_num = "dawdawdaw",
note = "note",
price = 15,
date = 2017-05-17,
totalPay = 16,
expiration_date = 2017-06-16,
WHERE id = 1;
if I run this SQL statement it throws the following syntax error:
WHERE[*] id = 1 "; expected "identifier"; SQL statement:
What did I do wrong?

Is this Java code? If so, then some of your variables look to be in the wrong format. Strings need to be bounded with double quotes. Not sure about those data values.
|
|

|

Thanks for your reply I edited the values of the String type with the double quotes
|
|
|
|

You have an additional comma after the last column to be set:
expiration_date = 2017-06-16, The parser expects another column to be set beginning with an identifier but it found the WHERE keyword.
So remove that comma:
UPDATE data SET
full_name = "SARA",
reg_num = "dawdawdaw",
note = "note",
price = 15,
date = 2017-05-17,
totalPay = 16,
expiration_date = 2017-06-16
WHERE id = 1;

Thank you so much it works now

Are you sure? I suspect you'll probably need quotes around the date values. Otherwise, 2017-05-17 will become 1995.

"it's working now" probably means no exceptions were thrown.

Dates are not handled this way.
This
date = 2017-05-17
translate as
date = 1995
