View Replies View RelatedAdding Rows And Columns In A Matrix?
Apr 16, 2015I have a 5x5 array of which I read from an external file and I am supposed to print out the original matrix and then add up each row and column, proceeding to store them into the sixth positions in my matrix. After that I print out the new matrix.
For example this just using a 2 by 2,
Original
1 2 3 4 5
1 2 3 4 5
New 3 by 3
1 2 3 4 5 15
1 2 3 4 5 15
2 4 6 8 10 30

Find Number Of Rows In CSV File
Feb 13, 2014I am working through a text and I am supposed to complete the following tasks.
Your ReadFiles.java class requires the following methods:
Method: check to see if the file exists
Method: find number of rows in csv file
Method: Converts the csv file to a mutli-dimensional array
Method: PrintArray
Method: Return array using a get method
Create a file DataAnalyzer.java. This file will be used to call the methods in ReadFiles.java. Be sure to demonstrate that all of your methods work through DataAnalyzer.java.
The problem is that it does not really provide any information on how to go about reading a file into an array. I am stuck at the third task of converting the file to an array and I have tried several ways to do this unsuccessfully. I thought that I would at least try to get things to print out (line 87) to see if I could get that to work, but all that prints in null over and over again.
Java Code:
public class DataAnalyzer {
public static void main (String[] args) {
ReadFiles aReadFiles = new ReadFiles();
aReadFiles.fileCheck();
aReadFiles.findRows();
aReadFiles.convertFile();

JDBC :: BatchUpdate Rows Affected Is Always -2
Mar 27, 2015I have a batch process which does Bulk UPDATE statement.
After implementing batch support using Spring JDBC 4.1.6 and Oracle Jdbc Driver (ojdbc7 and ucp), the number of records affected for individual update requests (in the batch) are always retrieved as -2 (Statement.SUCCESS_NO_INFO).
Is there any way to know the rows affected for individual cases, as I have to retry the same argument with an INSERT statement after this. Technically trying to develop this as an UPSERT implementation
I tried this batch update in Three Different Ways, and in all three methods the results are same -- (It just tells me Statement.SUCCESS_NO_INFO (-2) )
Method 1 -- Direct UCP Connection and PreparedStatement
connectionPoolMgr.startConnectionPool("mgr_pool");
Connection connection = pds.getConnection();
PreparedStatement pstmt = connection.prepareStatement(dmlSQL);
pstmt.setInt(1, pkId);
pstmt.setInt(2, idx * 10);
pstmt.addBatch();

Rows And Columns In The Form Of Multiplication Table?
Mar 12, 2014I am making rows and columns in the form of a multiplication table, listed below is my code:
package assignments;
public class MultTable {
public static void main (String [] args) {
int row, column, x, y;
for(row = 0; row < 8; row++)
[Code] .....
If you see my sample run you can see that I have the multiplication table down but, I haven't completed it. I have to make the bottom left half of the whole table blank somehow. For example, I have to make it halfway through the middle of the table the bottom left half full of white space...
5 6 7 8 9
12 14 16 18
21 24 27
32 36
90
hm, it's supposed to be the other way around horizontally.

JSP :: Best Way To Retrieve Thousand Rows From Database For Encoding?
Mar 6, 2015I have to create a webpage such that there is an 'import' and 'save' button.
When the user clicks import button, it will retrieve inventories under PRODUCTS table which contains product title, SRP and Sold by (input field) under his account. Average possible returned rows will be around 1k-5k. If the 'Sold By' has value, it will show as read only. But if not, it will be editable.
Then the user has a list of product IDS printed on a paper that was sold by his employees and he has to scan each product id and put the name of his employee under Sold By and the price sold. This is a manual procedure..
Then after he finishes encoding, he has to click save button to save changes in the db.
what is the best way to implement this? Is it efficient to use js functions such as datatables?

Matrix Algebra - Number Of Rows And Columns
Mar 19, 2015I am continuing on in trying to build up the basics of matrix algebra from scratch.
I have created an object class called Matrix
import java.util.ArrayList;
public class Matrix {
public int NumRows;
public int NumColumns;
// This array contains the entries of our matrix.
ArrayList<Double> entry = new ArrayList<Double>();
[Code] ......
Bottom line: a matrix has a number of rows and a number of columns, and for each pair of row and column, we have a number in our matrix. The DisplayMatrix method prints my matrix to the screen, and the GetEntry method returns a particular value. This all works fine and dandy as far as I can tell.
A fundamental operation done to matrices to obtain a special matrix called the RREF is the process of switching 2 rows. Here is a method I have written that switches two rows of a matrix, and outputs the result as a new matrix. Note that I want the original matrix to be unchanged.
// Switch two rows
public static Matrix SwapRows(Matrix A, int r1, int r2){
if(r1<1 || r1>A.NumRows || r2<1 || r2>A.NumRows)
PRINTLN("illegally switching rows");
Matrix C = A;
double dummy[] = new double[A.NumColumns];
[Code] ....
How I call this, inside a public static void main(String[] args), is as follows:
// Declares that A is a 2 by 2 matrix.
Matrix A = new Matrix(2,2);
// We now add values in. The top left entry of A is 4, the top right entry of A is 1, the bottom left entry of A is 2, and the bottom right entry of A is 6.
double pony[]= new double[4];
pony[0]=4;
pony[1]=1;
pony[2]=2;
pony[3]=6;
A.AddEntries(pony);
// We can display the matrix in the output, and it looks exactly as expected!
A.DisplayMatrix();
// I am now going to create a new matrix called B. It is going to be obtained by flipping the first and second rows of A.
//Note that I want A is stay as I initialized it.
//I dont want A to have it's 2 rows switched. I want B to the matrix obtained by switching two rows of A.
Matrix B=SwapRows(A,1,2);
B.DisplayMatrix();
// Displaying B gives me the desired result. However, if I now display A again, it is the same as B.
A.DisplayMatrix();
Why is my matrix A being modified? Of course, I am more than capable of providing more details/comments if requested. I suspect that this is a super silly mistake.
