On the Codechef August long challenge, AUG21C > CHFINVNT, this is the code that I wrote, but the submit doesn't work. It's showing RE(NZEC) error.
The output still works.... but it won't submit. Please help.

Obviously, you have a flaw in your code. NZEC means non-zero exit code. Your code probably triggered an uncaught exception. Although you have a broad catch statement, there are exceptions outside of your catch clause.
In the question statement, N can be as large as 10^9.
If that happens, int[] A = new int[N]; tries to allocate that memory. That is over the memory constraints. Probably that is causing the problem. Even if you could allocate that memory, you would hit the time limits: even counting to 10^9 shall fail on CodeChef.
Not directly related to the question, but I want to comment on your code from the perspective of software engineering and competitive coding best practices.
Having a broad catch block will hide any exceptions you may have. Even if you get an index-out-of-bounds exception, you shall not be able to see that in your trials. You may avoid catching broad exceptions.
Your code does not have a proper indentation. That makes reading & debugging cumbersome. Especially in competitive programming, speed is important. So, a proper indentation is critical in that regard. You may just use an IDE to format the code.
Your Java code does not follow the general conventions of Java. One of the rules is "local variables start with a lowercase". The local variables A and N violate that rule.
The code you submitted contains many empty lines. While submitting your code to StackOverflow, removing unnecessary lines shall ease the reading and increase the probability of getting a good answer.

If keep receiving runtimeException

I tried your code over the site you mentioned. I changed the class visibility to be default to avoid some compilation error. It produced internal error with no further details and it suggested to test the code on https://ideone.com/ site. I used the sample test case and it passed successfully on ideone site..I suggest that you use hacker rank, I think it is more handy. In hacker rank you can unlock test cases to trace errors, bugs in your code, also you can have discussion with colleagues there over the problem. On the other hand I couldn't get the exception you mentioned "NoSuchElementFoundException" if you have detailed stack trace kindly include it and I shall update my answer accordingly.

Some meta-help for future reference:
Compiler errors: these are when you experience an error that occurs at compile time. For Java, this is when you use javac, and your Java code is being turned into bytecode files for interpretation later.
Runtime errors: this is when you experience an error that occurs when you run your code. For Java, this is when you use java, and your Java code is being run.
If you find the two confusing, add into your question the thing you typed in order to experience the error. Specify all the flags and options you used, and format it with a code block, for example like this:
java -jar code.jar
When asking questions here - or indeed anywhere on the web where you can get technical help - try to ask yourself what clarifications you would need if you saw your question for the first time. Your first edit did not include your code, so ask yourself: would you be able to ascertain someone else's similar problem without code? Broadly here the answer is "no", and thus the moral of this story is: always include your code.
Also, do spend a moment to learn the code formatting tools. To use them, paste your block of code into the question, select it, and click the "code" button. It will apply a four-space Markdown indent, which you can now see in the question.
If you need to add clarifications to your post, it is OK to add them as comments, but do also edit the body of the question so that new readers can understand the question. It is well worth spending time making it as readable and clear as possible, so you can get the best possible help, and so that people do not take a look and decide that another question is a better use of their time.
Since you are using an IDE, do you get any warnings/errors in the editor, to help you identify potential problems in you code? If so, and you do not understand them, then paste them into your question, in order to clarify it.

Thanks for your advices... Finally made it working..

I want to add text fields a01, a02, ... to the array a.
I want to display the value of val so that I would know if the text is being taken from text fields. This code does not show any errors, but, well, it doesn't give me output as well.
int i, j;
JTextField[][] a = new JTextField[9][9];
int[][] val = new int[9][9];
for (i = 0; i < 9; i++)
{
for (j = 0; j < 9; j++)
{
val[i][j] = Integer.parseInt(a[i][j].getText());
System.out.println(val[i][j]);
}
}
It is from my old question here.

You did not give them value
int i,j; // counter
JTextField[][] a = new JTextField[9][9];
for(i=0;i<9;i++)
{
for(j=0;j<9;j++)
{
JTextField tf = new JTextField();
tf.setText("a"+i+j);
a[i][j] = tf;
}
}
In your version the call to a[i][j].getText() should throw a NullPointerException. This should either kill your application, end up on the console or you have somewhere something like
try {
// more code here
} catch (Exception ex){}
which will silently swallow the exception and is veeeeery bad practice.

The code you have shown us does generate an error - it throws a NullPointerException when you try to access the text of the text fields via a[i][j].getText().
You didn't initialize the JTextFields in your array a.

It seems to be a very common question relating with arrays and comparing in java, however I couldn't find the right answer in all of these for my case.
In this application I am trying to make a program which 'encrypts' text given by the user. For example: user gives characters 'a b c' and the program returns it as '# # $'. But as you may notice I am having some issues in the code
"pozita[i] = j;".
Why won't this code work? It doesn't give me an error? Or is there anyway of doing it as "new pozita[i]" or anything like that?
Well, I'd be glad if someone could help me through. I am stuck for a while. Thanks in advance! :)
import java.util.*;
import javax.swing.*;
import java.awt.*;
public class TestPerProgram extends JFrame
{
char[] alfabeti = {'a','b','c','r','n','t'};
char[] kodimi = {'#','#','%','*','^','$'};
int[] pozita;
//Scanner merr = new Scanner(System.in);
String fn = JOptionPane.showInputDialog("Jepe tekstin:");
char[] input = fn.toCharArray();
void numro()
{
for (int i=0; i<=input.length; i++)
{
for(int j=0; j<=input.length; j++)
{
if(alfabeti[j] == input[i])
{
pozita[i] = j;
System.out.println(pozita[i]);
}
}
}
/*
for (int k=0; k<=input.length; k++)
{
System.out.println(pozita[k]);
}
*/
}
public static void main(String[] args)
{
TestPerProgram pjesa = new TestPerProgram();
pjesa.numro();
}
}

I'm not 100% clear on how your algorithm is supposed to work, but it seems you may want to replace the line
pozita[i] = j;
with
pozita[i] = kodimi[j];
Right now, you are only writing the matching index to pozita, not a replacement character.
If my assumption is correct, you would also change
int[] pozita;
to
char[] pozita;
and initialize it to an array of length input.Length.

You never instantiated the array pozita. After you instantiate pozita, you can then start overriding the values in pozita. You are assigning j to posita[i] , posita is null.
Do something like:
int posita[] = new int[20]
and if you don't want to set size then just use an arraylist.

You have not requested memory to be allocated for your variable pozita or otherwise instantiated it. The way you are currently using it, you would write pozita[] = new int[input.length]; at some point after retrieving your input from the user.
