I have a requirement to fetch the details from pos transaction and use it in my application(Based on Java) for business purpose.
Please suggest best possible solution to proceed.
on discussions i found few possible solution to start are Applets or Active X . But didnt get much information on how to start with any of the above option or any other possible solution.
Any input will be really appreciated
Thanks in advance

The first thing to research is how the POS presents its data, and through what interface.

I am unable a to understand a concept. double variable and double array are declared outside the function and a function which increments the value of both is made. Values from the functions are not returned still the value of the double array gets incremented where as it is not the same case with double variable. Why ? Same with Double class
double x = 100.5;
p.m1( x );
System.out.println("" + x);
double[] xa1 = {10,20,30,40};
for (int i=0;i<4;i++){
System.out.println(xa1[i]);
}
public void m1(double a) {
a += 100;
}
public void m5(double[] x) {
for(int i=0; i < x.length; i++)
x[i] += 100;
}
OUTPUT : 100.5
110.0 120.0 130.0 140.0

'a' is an instance and it is copied when you call m1().
'x' is a reference so when 'x' is used in m5() the original, not a copy is used.
The above is a simple explanation and it is not exactly true semantically but is true conceptually. But without understanding what you are trying to understand I don't want to explain what is actually going on.

how to read large 8gb json text file in java program.
I am try with FileInputStream in java but after 2gb it's not work.

If you are trying to read all that much data into memory then it will never work. You need to read it in smaller blocks and process only the data you can hold in memory.

It is not clear what your problem is. The above would appear to be some XML formatted data, so you can use the XMLReader (Java Platform SE 7 )[^] to extract the fields from it.

The spark of current version is used FMJ library as media library,
and so the voice chatting can't progress.
If the libjitsi library replace fmj, I don't know it to be impossible.

I have one large json file in that each cv have two or more degree ie mention.

In Cv there are lot of other degree so how to calculate exact 4 year completed degree ?
is there nay idea ?

How did you tell BE is 4-year degree? There isn't enough information. You have to add one more piece of information say "length of study" for each degree.

There is no way to do it with just those letters, as they could mean anything.

Hello,
I have an application that needs to print the contents of a JPanel, and I using this code
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(new Printable() {
@Override
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex > 0) {
return NO_SUCH_PAGE;
}
int marge=30;
int x = (int)pageFormat.getImageableX();
int y = (int)pageFormat.getImageableY();
graphics.setFont(new Font("Times new roman", Font.BOLD, 14));
graphics.setColor(Color.BLACK);
graphics.drawString("ACTE DEMANDER\n", x + marge, y + marge);
panel.print(graphics);;
return PAGE_EXISTS;
}
});
boolean doPrint = job.printDialog();
if(doPrint) {
try {
job.print();
}
catch (PrinterException e1) {
JOptionPane.showMessageDialog(null, e1);
}
}
and it works well, but that code display the border of JTextArea, which is supposed to be borderless after being printed and the content of this JTextArea are not all displayed texts are cut.
So I decided to print one by one the contents of this JPanel but its content does not switch to the line as I did in my interface but it is superimposed one above the other.
this is my second code
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(new Printable() {
@Override
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex > 0) {
return NO_SUCH_PAGE;
}
int marge=30;
int x = (int)pageFormat.getImageableX();
int y = (int)pageFormat.getImageableY();
graphics.setFont(new Font("Times new roman", Font.BOLD, 14));
graphics.setColor(Color.BLACK);
graphics.drawString("ACTE DEMANDER\n", x + marge, y + marge);
jLabel1.print(graphics);
jLabel2.print(graphics);
jLabel3.print(graphics);
jTextArea1.print(graphics);
jTextPane1.print(graphics);
return PAGE_EXISTS;
}
});
boolean doPrint = job.printDialog();
if(doPrint) {
try {
job.print();
}
catch (PrinterException e1) {
JOptionPane.showMessageDialog(null, e1);
}
}
How then could I do to make them lines or retrieve the contents of my JTextArea whatever the length of the text and there is newline. All help in both cases are welcome.
thank you for helping me
Best regards.

You define a
discrete random variable X that assumes values represent your awards and losses when you play the
game. For simplicity, assume that the awards are positive and the losses are negative. Each award
or a loss is associated with a probability. You run the game many times, at each time you randomly
select a value for the random variable and multiply the result by its probability. After m runs of the
programs, your program must give a recommendation whether you play the game or not.
Remember if the expected value of the random variable is negative, it is a losing game; wining
otherwise.
You program should allow the user to input the values of the random variable and their associated
probability and the number of runs m. After doing the experiment, the program prints the
recommendation.
please help i cant do it!!!!!
