My "for loop" on java only return the result on the first row of jtable and repeat it for the rest number of row

So I have some issue on my for loop. It only work on the first row of jtable and printed the same result to the whole rows. here's my code:
try {
int row = tblHasil.getRowCount();
for (int i = 0; i < row; i++) {
String tempA = (String) tblHasil.getModel().getValueAt(i, 3);
String tempB = (String) tblHasil.getModel().getValueAt(i, 4);
String tempC = (String) tblHasil.getModel().getValueAt(i, 5);
double a = Double.parseDouble(tempA);
double b = Double.parseDouble(tempB);
double c = Double.parseDouble(tempC);
VNilaiRataRata.setNilaiRataRata(a);
VTanggungan.setTanggungan(b);
VPenghasilan.setPenghasilan(c);
Rules.hitung_u();
Rules.hitung_z();
DecimalFormat df = new DecimalFormat("#########.###");
double hasildef = Double.parseDouble(df.format(Rules.defuzzifikasi()));
VKeterangan.setKeterangan(hasildef);
double keterangan = VKeterangan.getKeterangan();
double tidakLolos = VKeterangan.tidaklolos();
double cadangan = VKeterangan.cadangan();
double lolos = VKeterangan.lolos();
String desc;
if (lolos > cadangan && lolos > tidakLolos) {
desc = "Lolos";
tblHasil.setValueAt(desc, i, 6);
} else if (cadangan > tidakLolos && cadangan > lolos) {
desc = "Cadangan";
tblHasil.setValueAt(desc, i, 6);
} else {
desc = "Tidak Lolos";
tblHasil.setValueAt(desc, i, 6);
}
System.out.println("Nama : " + tblHasil.getModel().getValueAt(i, 1));
System.out.println("Hasil Fuzzi : " + hasildef);
System.out.println("Keterangan Value : " + keterangan);
System.out.println("Keterangan Tidak Lolos : " + tidakLolos);
System.out.println("Keterangan Cadangan : " + cadangan);
System.out.println("Keterangan Lolos : " + lolos);
System.out.println("Nilai Rata2 : " + VNilaiRataRata.getNilaiRataRata());
System.out.println("Tangungan : " + VTanggungan.getTanggungan());
System.out.println("Penghasilan : " + VPenghasilan.getPenghasilan());
System.out.println("Keterangan : " + desc);
System.out.println("================================");
System.out.println();
Connection cn = DriverManager.getConnection("jdbc:mysql://localhost/db_siswa", "root", "");
int nis = Integer.parseInt(tblHasil.getModel().getValueAt(i, 0).toString());
String sql = "UPDATE nilaisiswa SET hasil='" + desc + "' WHERE nis = '" + nis + "'";
cn.createStatement().executeUpdate(sql);
}
} catch (Exception e) {
e.printStackTrace();
java.util.logging.Logger.getLogger(Proses.class.getName()).log(Level.SEVERE, null, e);
}
And here's the result (marked with red circle) :

xmlhttp.status returns 0

I have this java script code for ajax and I'm having trouble of get response.
xmlhttp.status always become 0. I have repeatCallHr Servlet and getting parameters from jsp page as follows.
function loadResults() {
var tt = document.getElementById("StartDate");
alert(tt);
if (xmlhttp) {
var query = "repeatCallHr?skill="
+ document.getElementById("ServiceCode").value
+"&startDate="+document.getElementById("StartDate").value
+"&startTime="+document.getElementById("StartTime").value
+"&endDate="+document.getElementById("EndDate").value
+"&endTime="+document.getElementById("EndTime").value;
xmlhttp.open("GET", query, true);
xmlhttp.onreadystatechange = loadStallsResponse;
xmlhttp.send(null);
} else {
alert("Browser not supported!");
}}
In following code I'm calling AJAX request and try to get response out of it.
function loadStallsResponse() {
alert("come here");
alert(xmlhttp.readyState);
if (xmlhttp.readyState == 4) {
alert("status is :"+xmlhttp.status);
if (xmlhttp.status == 200) {
resultList = [];
if (xmlhttp.responseText.indexOf("Error") == -1) {
alert("come to inside of status::")
console.log(xmlhttp.responseText);
stallList = $.parseJSON(xmlhttp.responseText);
populateStallData();
} else {
alert(xmlhttp.responseText);
}
} else {
alert("Error in loading salesman data");
}
}}
function populateStallData() {
var table = "<tr><th>Date</th><th>Time</th><th>Skill</th><th>Total Call</th><th>Unique Calls</th><th>Repeat Calls</th></tr>";
for (var i = 0; i < resultList.length; i++) {
table += "</td><td width='140'>"
+ resultList[i].date
+ "</td><td width='140'>"
+ resultList[i].time
+ "</td><td width='140'>"
+ resultList[i].skill
+ "</td><td width='140'><a style='color: -webkit-link; text-decoration: underline; cursor: auto;' href='http://"
+ resultList[i].totalCall
+ "</td><td width='140'>"
+ resultList[i].uniqueCall
+ "</td><td width='140'>"
+ resultList[i].repeatCall
+ "</td></tr>";
}
document.getElementById("ResultTable").innerHTML = table;}
But it gives xmlhttp.status as 0. Please help me to figure out what is the issue.

Want to filter products based on price of the products and print the filtered one

I am trying to filter the products by getting listOfProducts and ittirating over it..
public List<Products> filterByPrice(int min,int max){
List<Products> listofproducts = products.retrieveProducts();
System.out.println(listofproducts +" size: " +listofproducts.size());
for (Products productsVar : listofproducts) {
if(productsVar.getPrice()>= min && productsVar.getPrice()<= max){
return listofproducts; //here how do i print the reduced listOfProducts
}
}
return null;
}
May be its very easy one but not getting how to print out the reduced filtered products from the list
Thanks

You are printing and returning the whole list, try this:
List<Products> listofproducts = New List<Products>();
//System.out.println(listofproducts +" size: " +listofproducts.size());
for (Products productsVar : products.retrieveProducts()){
if(productsVar.getPrice()>= min && productsVar.getPrice()<= max){
listofproducts.add(productsVar);
}
return listofproducts; // may return blank list if no products fall between min and max price range

The best way for doing this is Java 8 Streams
List<Products> filteredListOfProducts = listofproducts.stream()
.filter(p -> p.getPrice >= min && p.getPrice() <= max)
.collect(Collectors.toList());
...
return filteredListOfProducts;
You can add here a lot of other type of your products processing. See java.util.stream.Stream javaDoc

This code is to add a price range and value filter for products
Please correct if wrong :)
Add this method to your sevlet
public int[] getMaxMinForConstraint() {
int[] array = new int[4]; //statement
String query = "SELECT min(price),max(price),min(owners),max(owners) from products";
PreparedStatement pst = null;
ResultSet rs = null;
try {
pst = conn.prepareStatement(query);
rs = pst.executeQuery();
if (rs != null) {
if(rs.next()) {
for(int i=1;i<=4;i++)
{
array[i-1]=rs.getInt(i);
}
Then add this code to your jsp or html to insert slider for price and input box for number of owners
<div class="slider">
<label>Custom Price</label>
<div id="price" data-min="0" data-max="
<%=getMaxMinForContraint[1]%>" data-min-name="min_price" data-max-name="min_price"
data-unit="USD" class="slider" aria-disabled="false"></div>
<div class="clearfix"></div>
</div>
<div class="form">
<div class="input">
<select id="owners" class="form">
<option value=""> </option>
<%for (int i = getMaxMinForConstraint[3]; i <= maxminValuesForSearch[4]; i++) {%>
<option value="<%=i%>"><%=i%></option>
<%}%>
</select>
<i class=""></i>
</div>
</div>
<button class="btn" onclick="myfun()">Find Product</button>
Then add this function to find the product
function myfun()
{
var $min_price = $("#price").slider("values", 0);
var $max_price = $("#price").slider("values", 1);
var $owners = $("#owners").val();
if ($min_price == null || $min_price == "" || $min_price < 0)
$min_price = -1;
if ($max_price == null || $max_price == "" || $max_price < 0)
$max_price = -1;
if ($owners == null || $owners == "" || $owners < 0)
$owners = -1;
var obj = {
"min_price": $min_price,
"max_price": $max_price,
"owners":
};
//alert(JSON.stringify(obj));
// console.log(JSON.stringify(obj));
var string = ""
$.ajax({
type: "post",
url: "SearchProduct",
//cache: false,
data: JSON.stringify(obj),
success: function (result) {
manageHtml(result);
},
error: function () {
alert("Request can not Proceed at this time");
}
});
}
function manageHtml($r)
{
var $str;
var $table = $("#example1").DataTable();
$("#arrnum").text($r.length);
$("#example1").empty();
//$("#tb1").html("");
for (var i = 0; i < $r.length; i++)
{
}
$str = "<tr><td><div class=\'col-lg-12 col-md-12\'><div class=\'product listing, product 1\'><div class=\'product\'><a href=\'SingleProduct.jsp?id=" + $r[i].id + "\'><img src=\'" + $r[i].pictures + "\' class=\'img-fluid \' alt=\'\'><\/a>" <h4 class=\'productname\'><a href=\'SingleProduct.jsp?id=" + $r[i].id + "\'>" + $r[i].name + "<\/a><\/h4><img src=\'\/img\/addProduct.png\' class=\'img-fluid'><\/a><\/div><\/div><div class=\'price\'><h4 class=\'price\'>$ " + ($r[i].price) + " <\/h4><\/div><div class=\'detail-btn\'><a href=\'SingleProduct.jsp?id=" + $r[i].id + "\' class=\'more-btn\'>More Info<\/a><\/div><\/div><\/div><\/div><\/div><\/td><\/tr>";
console.log($str);
$("#example1").append($str);
Finally add the following code to your search product servlet
String jsonString = "";
BufferedReader br
= new BufferedReader(new
InputStreamReader(request.getInputStream()));
String json = "";
if (br != null) {
jsonString = br.readLine();
System.out.println("recieve" + jsonString);
}
System.out.println(jsonString != null);
if (jsonString != null /*&& logged_in && role.compareToIgnoreCase("buyer")==0*/) {
int buyer_id = ((BuyerDAO) session.getAttribute("buyer")).getId();
JSONObject obj = new JSONObject(jsonString);
int min_price, max_price,
int owners;
min_price = obj.getInt("min_price");
max_price = obj.getInt("max_price");
owners = obj.getInt("owners");
String condition = "";
if (min_price != -1) {
condition += "price>=" + min_price + " And ";
}
if (max_price != -1) {
condition += "price<=" + max_price + " And ";
}
if (owners != -1) {
condition += "owners=" + owners + " And ";
}
condition += "1=1";
ProductDB db = new ProductDB();
//set buyer id from seesion
JSONArray arr = new JSONArray(db.getAllProducts(condition, buyer_id));
// System.out.println("recieve" + obj.toString());
out.println(arr.toString());
} else {
out.println("0");
}
} else {
out.println("0");

Better to use Apache POI and do one thing if you are not using maven download the below jars and keep it in your lib
dom4j-1.6.1.jar,
poi-3.9-20121203.jar,
poi-ooxml-3.9-20121203.jar,
poi-ooxml-schemas-3.9-20121203.jar,
xmlbeans-2.3.0.jar
and then using some classes you can read excel file even a row wise or cell wise
Try this I Hope this will you.....

Hope this helps`
public class ReadExcelfile {
public static void main(String[] args) throws Exception {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Statement stmt = DriverManager.getConnection("jdbc:odbc:employee").createStatement();
ResultSet rs = stmt
.executeQuery("select lastname, firstname, id from [Sheet1$]");
while (rs.next()) {
String lname = rs.getString(1);
String fname = rs.getString(2);
int id = rs.getInt(3);
System.out.println(fname + " " + lname + " id : " + id);
}
rs.close();
stmt.close();
}

How to make pagination using sublist

hello there i got a problem with pagination with sublist..
right know i can load the first 50 data from data..but when i click "2" link to load other page its doesnt load anything i notice that my code is use from and to and it will load only from and to..but how to increment from and to???can anyone give me some example..
here is the example
int from= 0;
int to = 50;
List subList = logList.subList(from, to);
//pagination
if (logList.size()>50){
setTotalSessionRecord(logList.size());
int sessionCountPages = (logList.size()/subList.size());
if ((logList.size() % subList.size()) > 0) {
sessionCountPages++;
}
setTotalSessionPage(sessionCountPages);
if (getSessionPage() == 0) {
setSessionPage(1);
} else if (getSessionPage() > getTotalSessionPage()) {
setSessionPage(getTotalSessionPage());
}
int startPages = (getSessionPage() - 1) * logList.size();
startPages++;
arg = new ArgumentBuilder();
arg.addArg(getSessionLogId());
arg.addArg(startPages);
arg.addArg(logList.size());
arg.addArg(isAsCending());
//end of pagination
in my jsp
function toSessionPage(sessionPage, ascOrderSession , id,
folderId , numberOfSessions , selectedSessionPages) {
var tURL = '<%=request.getContextPath()%>/home/Folder.action?
listSessionLogEvents=&sessionLogId=' + id + '&folderID=' + folderId +
'&sessionPage=' + sessionPage + '&numberOfSessionPages='+ numberOfSessions
+ '&selectedSessionPages=' + selectedSessionPages
+ '&asCending=' + ascOrderSession ;
jQuery.ajax({
url: tURL,
dataType: 'html',
success: function(returnData) {
jQuery('#detailTR' + id).html(returnData);
}
});
}
function toSelectedSessionPages(sessionPage, selectedSessionPages,
ascOrderSession,id ,folderId) {
var tURL = '<%=request.getContextPath()%>/home/Folder.action?
listSessionLogEvents=&sessionLogId=' + id + '&folderID=' + "11"
+ '&sessionPage=' + sessionPage + '&selectedSessionPages='
+ selectedSessionPages +'&asCending=' + ascOrderSession ;
jQuery.ajax({
url: tURL,
dataType: 'html',
success: function(returnData) {
jQuery('#detailTR' + id).html(returnData);
}
});
}
in load jsp..
<td align="center" width = "60%" >

<%
int toSessionPage = 0;
if(fa.getTotalSessionPage() - fa.getNumberOfSessionPages() > 20){
toSessionPage = fa.getNumberOfSessionPages() + 19;
}else{

}
int i = 0;
