JDBC :: How To Determine DATE Data Type Of Parameter If It Is Not Specified

Feb 2, 2015

Oracle JDBC driver determine the DATE data type of parameter correctly without any typecasting.

Example:
ps = conn.prepareStatement("SELECT ? FROM DUAL");
ps.setObject(1, Date.valueOf("2014-01-11")) ;
 
I have tried the same example with other database driver but it gives error.

PostgreSQL JDBC driver:
org.postgresql.util.PSQLException: ERROR: could not determine data type of parameter $1
 
ps = conn.prepareStatement("SELECT ?");
ps.setObject(4, Date.valueOf("2005-01-01"));
 
so I want to know how Oracle JDBC driver determine the DATE data type of parameter.

Read Date From File / Calculate And Then Displays That Data In Table Format On Screen

Apr 22, 2015

The intent of the code is to read date from a file, does calculation and then displays that data in a table format on the screen. Then creates another file with those values:

Reads file: Beginningbalance.txt
Displays Data with calculation
Creates a file called "Newbalance.txt" with the following values:

111
251.41
222
402.00

With the way the code is written I can get it to create the file but it only displays one of the customers (111). I know that I need to create a loop but I am not sure how to build that. I tried creating another while loop and changing it to outFile but that was without success.

import java.io.*;
import java.util.Scanner;
import java.text.DecimalFormat;
public class Output {
public static void main(String[]args) throws IOException {

Given a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?

Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...

I am looking for 01,02,03 etc...

Replacing Characters In Array?

Mar 7, 2014

Is that the only way to code the JOptionPane? Seems rather similar to Sys.out

--- Update ---

I had more than this, but post was deleted somehow and this was the gist of it:

for(i = 0 ; i < charArray.length; i++){
if(Character.isDigit(charArray(i))){
address.replace("6", "*");
address.replace("7", "*");

Is there a better way to scan a character array for digits and replace any number in the array with another character ("*") in this case? The array is the address, " 1234 Runner Road " .

Replacing Old With New Values In Array

May 24, 2014

how to replace the values in my array with the results of my function factorial.

public static void main(String[] args) {
//this is my main function:
int[] array = {5,4,3,2,1};
int i = 0;
System.out.print("results: ");
for (i = 0; i < array.length; i++){
System.out.print(factorial(array[i]));

[code]....

So, what I'm trying to do is change the contents of the array "array" into their factorial value. So, they should be replaced with {120,24,6,2,1}. then add those using linear sum but that's a different story.

Replacing And Checking Character In String?

Jul 24, 2014

so my task is to write a code which would ask user to input the year as integer and first three letters of the month with first being an upper case letter. Than the program would determine the number of days for given year and month.

Currently I have a brain crash on how to check, if the user has provided the month with first character being upper Case. If not, than the program would automatically correct the character. Problem starts at line 17.

import java.util.Scanner;

public class DaysOfMonth4_17 {
public static void main (String[] args) {
//Initiate scanner
Scanner input = new Scanner (System.in);
//Ask for year input and use is as INT
System.out.println("Enter the year");

DAO Based Application - Replacing Old Textfile

Apr 16, 2014

I'm currently trying to build a DAO based application where you use a text file as a data source. It have worked out well until I tried to delete lines from the file.

public void delete(DTOBil dtobil) {
try{
reader = Files.newBufferedReader(Paths.get("databilar.txt"),charset);
writer = Files.newBufferedWriter(Paths.get("temp.txt"), charset, StandardOpenOption.CREATE_NEW);
String line = null;
while((line = reader.readLine()) != null){

[Code] ....

I've managed to fill out the temp file with everything except the line I wanted to remove, but when I try to replace the original file with the temp file it won't work. It casts the error: "temp.txt -> databilar.txt".

I've also tried to use the renameTo method without any success...

Replacing Null Values Within Multidimensional Array

Feb 18, 2014

I have a file which contains certain positions ([a][b]) that require to be placed in a certain multi-dimensional array. For example I might have an array String[][] that is a size of 6x6 but only have values in positions [2][1] and [3][2]. Because it is important for me to maintain the given array size and also do certain actions with the given positions I cannot modify the size. In addition I need to count the surrounding neighbors each element has (including elements that are null). However because some of my further code cant process with null elements I need to remove all null elements with " " (blank).

I am not sure how this is done or if it's even possible. If it is not possible how can I do something as close as possible to my needs?

Regex Replacing Entire Text Rather Than Match

Feb 14, 2014

With the code below, I am trying to replace all regex matches for visa cards within a given text file.

My first test was with a text "new3.txt" exclusively containing the visa test card 4111111111111111. My objective was to replace the card with "xxxx-xxxx-xxxx-xxxx". This was successful.

However, when modifying the text file to include other characters and text before and after (ex: " qwerty 4111111111111111 adsf zxcv"), it gives mixed results. Although it successfully validates the match, it replaces the whole text in the file, rather than replacing solely the match.

When trying this search and replace with words (rather than a regex match), it does not have this behavior. What am I missing?

import java.io.*;
import java.util.regex.*;
public class BTest
{
//VISA Test
private final static String PATTERN = "(?s).*4[0-9]{12}(?:[0-9]{3})?.*";
public static void main(String args[])
{
try

[Code]...

StringBuilder - Replacing Each Letter Without Reverse Tool

May 28, 2014

How can I replace each letter for example "abcde" to "edcba" with StringBuilder only and without the reverse tool. This is what I tried:

StringBuilder str=new StringBuilder("abcde");
int indexBegin=0;
int indexEnd=4;
for(int i=0;i<str.length();i++){
str.setCharAt(i, str.charAt(indexEnd));
indexEnd--;
}
System.out.println(str);

The output is:edcde with i understand why its wrong ,the last two letters already swap so it didnt take from the original str.

Replacing String In Case Of Exact Match Only

Oct 15, 2014

I have 2 strings

String value ="/abc_12_1/abc234/abc/filename.txt";
String src="abc"
Sring tgt=xyz

Now I have to replace the string in variable value in case of exact match; I am trying to do the following :

if(value.contains(src)
{
value.replaceall(src,tgt);
 }

Now the problem here is it replaces all the occurrence of abc in the string value and I get the below output as :

value=""/xyz_12_1/xyz234/xyz/filename.txt";

However my requirement is only in the case the value exactly matches with source the replacement shd happen. I am expecting the output like this :

String value ="/abc_12_1/abc234/xyz/filename.txt";

Also the above code is in a function which will be called multiple times and the values will keep  on changing. However the target and source will remain the same always.

Replacing Underscores In Array Implementation Of Hangman Game

Jun 5, 2014

For an array implementation of a Hangman game I have created an array to hold the game board progress. It is initialized as "_ _ _ " where the underscores represent the number of letter in the word to be guessed. I have written the following method to replace underscores with a correct guess. It is functioning correctly in that it is replacing the underscore with a correct character guess, but it is only replacing the first time this letter appears in the word. I.e. for "greed" guessing "e" would only replace the first e: _ _ e _ _how I may be able to fix this issue.

// Updates gameboard from "_" to current guess if guess is correct
if (isCorrectGuess(move)==true){
if(inWinningState()==false){
guessProgress[charLocation] = guess;}
return true;}

JavaFX 2.0 :: Replacing SplashScreen With Preloader Stage - Flickering?

Aug 29, 2014

I'm trying to set up a splash screen where a native splash screen is shown initially and then replaced with the stage from my preloader.  This is fairly simple to do.  I use the below code to get everything lined up properly. 

private void alignStage(Stage stage) {
    SplashScreen splashScreen = SplashScreen.getSplashScreen();
    if (splashScreen != null) {
        // Align the stage based on the current splash location
        Rectangle bounds = splashScreen.getBounds();
        stage.setX(bounds.getX());
        stage.setY(bounds.getY());

[Code] ....
 
The problem I'm having is that my Stage isn't actually shown by the time the commented event gets fired.  The API for onShown says:
 
Called just after the Window is shown.

My guess is the window has transitioned to being shown, but there's a slight delay until it gets rendered on screen.  If that's a decent assumption, is there a reliable way I can make sure my preloader stage is visible on screen before I hide the native splash?
 
The best option I can think of so far is to delay hiding the native splash until the preloader gets the BEFORE_START notification.  This works (no flicker), but, since both splash screens are actually visible for a while, using a transparent splash doesn't work very well (which actually isn't too big of a deal).
