How to sort data in a table data structure in Java?
- by rgksugan
I need to sort data based on the third column of the table data structure. I tried based on the answers for the following question. But my sorting does not work. Please help me in this.
Here goes my code.
Object[] data = new Object[y];
rst.beforeFirst();
while (rst.next()) {
int p_id = Integer.parseInt(rst.getString(1));
String sw2 = "select sum(quantity) from tbl_order_detail where product_id=" + p_id;
rst1 = stmt1.executeQuery(sw2);
rst1.next();
String sw3 = "select max(order_date) from tbl_order where tbl_order.`Order_ID` in (select tbl_order_detail.`Order_ID` from tbl_order_detail where product_id=" + p_id + ")";
rst2 = stmt2.executeQuery(sw3);
rst2.next();
data[i] = new Object[]{new String(rst.getString(2)), new String(rst.getString(3)), new Integer(rst1.getString(1)), new String(rst2.getString(1))};
i++;
}
ColumnComparator cc = new ColumnComparator(2);
Arrays.sort(data, cc);
if (i == 0) {
table.addCell("");
table.addCell("");
table.addCell("");
table.addCell("");
} else {
for (int j = 0; j < y; j++) {
Object[] theRow = (Object[]) data[j];
table.addCell((String) theRow[0]);
table.addCell((String) theRow[1]);
table.addCell((String) theRow[2]);
table.addCell((String) theRow[3]);
}
