How do i write in Excel file the value of individual popup and each popup contains the table

The below code executes on 21 rows and, when clicking on each row, a popup appears which contains a table that I need to write to an Excel file.
Row 0, 1,2 and 3 are just printing the name of page and other headings.
From the row 5th it should print each table of each popup(21 popups value).
Following code writing only last measure and also printing only the last row of that particular table(popup). I don't know to increment the rows for next popup/table to write on excel also need to increase the number of rows for a inner loop for(int j=0;j<totalNoOfLOB.size();j++) to print all values.
And int totalNoOfPopupRows =totalNoOfRows+1; gives me the total number of rows for each popup. Any help will be appreciated.

compare lines in JTextArea

Im working on a project where I create an online-shop-like application. Have everything working apart from last thing, which is reading the whole basket(items added to basket)
I have a button that adds item to the order(they are displayed in jtextarea).
I have another button that finishes shopping and is supposed to print your items which were added to jtextarea. Unfortunately I was only able to figure out how to read the last line in jtextarea. so basically what happens :
customer orders x, amount 1
customer orders y, amount 3
customer orders z, amount 7
It will only print the last line. any suggestion?
Here is the code
btnFinish.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int end = textArea.getDocument().getLength();
int start = 0;
try {
start = Utilities.getRowStart(textArea, end);
} catch (BadLocationException e1) {
e1.printStackTrace();
}
while (start == end)
{
end--;
try {
start = Utilities.getRowStart(textArea, end);
} catch (BadLocationException e1) {
e1.printStackTrace();
}
}
String text = null;
try {
text = textArea.getText(start, end - start);
} catch (BadLocationException e1) {
e1.printStackTrace();
}
System.out.println("(" + text + ")"); ```

how to implement a linked list properly using java

I am working in a project with linked list (JAVA) but I am not being able to figure out how to insert the person. How could I get the switch to work? Or should I use something else? I also thought about creating a class outside the main method and just call it but it did not work as well. Any help will be much appreciate
public void listOfPeople() { // Beginning of the method listOfPeople where shows the employees
// *** instance the person object ad loading your variables
Personqueue p1 = new Personqueue(); //saving the employee in a variable???
p1.setFname("John");

p1.setDOA(15);
p1.setPassportN(306589);
p1.setNumber(1);
vectorObj.add(p1); // add the employee in a vector
Personqueue p2 = new Personqueue(); //saving the employee in a variable???
p1.setFname("Paul");
p1.setLname("Clooney");
p1.setDOA(5);
p1.setPassportN(30614584);
p1.setNumber(2);
vectorObj.add(p2); // add the employee in a vector
}
public void ascendingOrder(Vector<Personqueue> vector) { // bubble sort method to order the vector
int j;
boolean flag = true; // set flag to true to begin first pass
Personqueue temp; // holding the variable temporarily
while (flag) {
flag = false; // set flag to false awaiting a possible swap
for (j = 0; j < vector.size() - 1; j++) {
if (vector.get(j).getNumber() > vector.get(j + 1).getNumber()) {
temp = vector.get(j); // swap elements
vector.set(j, vector.get(j + 1));
vector.set(j + 1, temp);
flag = true; // shows a swap occurred
}
}
}
}

Check your variables in listOfPeople(...), p2 was not used correctly.

for loop with ArrayList in java

i got a Productclass stored in ArrayList myValues.
I want to go trough each xth ( for example each 3th) element and have the user
add some Integer values to that class.
In my for(...) he tells me: The left-hand side of an assignment must be a variable. I wonder if i messed up some of the .get(j) or if i have to synchronize my methods so that the size wont change ( there is no multi-threading but maybe thats why i get an error?
) or the solution is more simple.
Thx
public void prioPerProduct (){
System.out.println("");
System.out.println("Please enter storing and upgrading cost:");
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
int storingCost = 0;
int ruestCost = 0;
int countRes = countRessources;
int sizemyValues = myValues.size();
for(int j = 0; j < sizemyValues; j = j+countRes){
System.out.println("Please enter storingcost " + myValues.get(j).getProduct() +":" );
try {
storingCost = Integer.valueOf(br.readLine());
} catch (NumberFormatException e) {
System.out.println("No number entered");
e.printStackTrace();
} catch (IOException e) {
System.out.println("No number entered");
e.printStackTrace();
}
System.out.println("Please enter upgradingcost " + myValues.get(j).getProduct() +":" );
try {
ruestCost = Integer.valueOf(br.readLine());
} catch (NumberFormatException e) {
System.out.println("No number entered");
e.printStackTrace();
} catch (IOException e) {
System.out.println("No number entered");
e.printStackTrace();
}
myValues.get(j).setstoringCost(storingCost);
myValues.get(j).setupgradingCost(ruestCost);
}
}

The left-hand side of an assignment must be a variable is generally caused by something like this:
methodCall() = somvalue...
The left hand side must be a variable rather than a method call. Your code looks fine in this regard.
The code where you declare your model class and a full stack trace are more helpful.

Use the set method to change the value of an object inside of an ArrayList.
myValues.set(j,myValues.get().setstoringCost(storingCost));
myValues.set(j,myValues.get().setupgradingCost(ruestCost));

Apache poi. Formula evalution. evaluteAll vs setForceFormulaRecalculation

[better quality]:. http://imageshack.us/photo/my-images/51/v5cg.png/
Problem: i use formulas in my workBook.xlsx. Depending on the circumstances i change value (3,3). At this example i changed 10 to 20. And after that i want to calculate the formula, which use this cell. When it has finished, it will override the value of the cells, remove formula and record the value. This cell no longer be used for the calculations again.
Code:
public class ReaderXlsx {
public List<List<String>> ReaderXlsx(String sfilename, int firstColumn, int columnsCount, int rowsCount, int moduleCount){
int lastColumn=firstColumn+columnsCount;
List<List<String>> rowsContent = new ArrayList<List<String>>();
try ( FileInputStream fileInputStream = new FileInputStream("C:\\Users\\student3\\"+sfilename+".xlsx");)
{
XSSFWorkbook workBook = new XSSFWorkbook(fileInputStream);
XSSFSheet sheet = workBook.getSheetAt(0);
int firstRow = findOneInFirstColumn(sheet,50);
setModuleCount(sheet,moduleCount);
workBook.getCreationHelper().createFormulaEvaluator().evaluateAll();
toNewLine:
for (int lineId=firstRow;lineId<rowsCount;lineId++) {
List<String> columnsContent = new ArrayList<String>();
Row row = sheet.getRow(lineId);
if (row==null){continue toNewLine;}
if (row.getCell(2)==null || row.getCell(2).getStringCellValue().equals("") ) {continue toNewLine;}
for (int columnId=firstColumn+1;columnId<lastColumn;columnId++) {
Cell cell = row.getCell(columnId-1);
if ((cell==null)) { continue toNewLine;}
cell.setCellType(Cell.CELL_TYPE_STRING);
if ((columnId==0 & cell.getStringCellValue().equals(""))) {continue toNewLine;}
if ((columnId==5 & cell.getStringCellValue().equals("")) || (columnId==6 & cell.getStringCellValue().equals(""))) cell.setCellValue("0");
columnsContent.add(cell.getStringCellValue());
}
rowsContent.add(columnsContent);
}
try(FileOutputStream out = new FileOutputStream("C:\\Users\\student3\\Used"+sfilename+".xlsx"); ) {
workBook.write(out);
out.close(); }
}
catch (IOException e) {
e.printStackTrace();
}
return rowsContent;
}
private Integer findOneInFirstColumn(XSSFSheet sheet, Integer maxRows){
int result=0;
toNextLine:
for (int lineId=0;lineId<maxRows;lineId++){
Row row = sheet.getRow(lineId);
if (row==null | row.getCell(0)==null) {result++; continue toNextLine; }
else{
row.getCell(0).setCellType(Cell.CELL_TYPE_STRING);
if (row.getCell(0).getStringCellValue().equals("1")){return result;}
else {result++;}
}
}
return result;
}
private void setModuleCount(XSSFSheet sheet, Integer moduleCount){
Row row = sheet.getRow(1);
if (moduleCount==0) {}
if (moduleCount>0) {row.createCell(2).setCellValue(moduleCount.toString());}
}
}
Now i use 2 files, because i need to save my formulas. I want to use only 1 (source) and update it correctly.
