Program To Read / Compare Time Intervals - Showing Wrong Output
Feb 24, 2015
the below program is to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class. and i have written like this
import java.io.*;
import java.util.*;
public class Main
{
static int k1,k2,v1,v2;
public static void main(String args[]) throws IOException

We use a Java program to read an XML file and put its content into a database. We also use Date() to get the current date and insert it into a field in database with content from XML file. Everything worked flawlessly until today, the last day of 2013. We are getting 2014 for the year instead of 2013!!! System date shows correct year, so this must not be an issue.

My code is :
try {
String s_ActivDate = getValueFromTable("S", "EXCEPTION_NAME", "EXCEPTION_NAME", s_exceptionName, "EXCEPTION_NAME_DATE_ACTIVE");
String s_InactiveDate = getValueFromTable("S", "EXCEPTION_NAME", "EXCEPTION_NAME", s_exceptionName, "EXCEPTION_NAME_DATE_INACTIVE");

I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:
- .... .
t
h
... - .-. .. -. --.
s
t
r
i
n
The English-->Morse works just fine.
import java.util.Scanner;
public class project1

"s", "t", "u", "v", "w", "x", "y", "z", " "

8
5/8
Enter numerator; then denominator.

I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error.
2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{
int value = 0;
Base(){
addValue();
}
void addValue(){
value += 10;

This is my code for the driver class:
import java.util.*;
public class SavingsAccountDriver {
public static void main(String[] args) {
System.out.printf("%10s%10s%10s%10s%10s" , "Month" , "Account #" , "Balance" ,
"Account #" , "Balance");
[Code] .....
Here is the output I get :
Month Account # Balance Account # Balance
----- --------- ------- --------- -------
0 10002 2000.00 10003 3000.00
1 10002 2002.00 10003 0.00
2 10002 2004.00 10003 0.00
3 10002 2006.01 10003 3030.00
4 10002 2008.01 10003 0.00
5 10002 2010.02 10003 0.00
6 10002 2012.03 10003 3060.30
7 10002 2014.04 10003 0.00
8 10002 2016.06 10003 0.00
9 10002 2018.07 10003 3090.90
10 10002 2020.09 10003 0.00
11 10002 2022.11 10003 0.00
12 10002 2024.13 10003 3121.81
Why is it not showing those months updated balance? I feel like I'm pretty close. I guess I should specify that this is supposed to calculate monthly interest for one account and quarterly interest for the other. This is what the output should look like.
Month Account # Balance Account # Balance
----- --------- ------- --------- -------
0 10002 2000.00 10003 3000.00
1 10002 2002.00 10003 3000.00
2 10002 2004.00 10003 3000.00
3 10002 2006.00 10003 3030.00
4 10002 2008.01 10003 3030.00
... ... 12 ... ...
The quarterly interest is the one that is giving me trouble.

I have 3 csv files as follows -
author file columns - emailID | firstname | lastname
books file columns - title | isbn | author_email | description
magazine file Columns - title | isbn | author_email | releasedate
I need to display -
1) Based on the ISBN display all books and magazines
2) All books and magazines by an author
3) All books and magazines by title
I am using Buffered reader as of now -
String csvFileToRead = "csvFiles/authors.csv";
BufferedReader br = null;
String line = "";
String splitBy = ";";
[Code] ....
I am confused about how to proceed with multiple files. Here are the approaches that i have considered -
1) change string csv csvFileToRead to a string array -
String[] csvFileToRead = {"data/autoren.csv", "data/buecher.csv", "data/zeitschriften.csv"};
Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?
2) Should i make 3 different classes with getters and setters for authors, book and magazine?

I am new to java and I have this assignment that I started but I am now stuck . The instructions are:
Create an ElapsedTimeCalculator class that computes the amount of time that passes between a starting time and an ending time, in military format.
For example, suppose the two times are 1445 and 1730. Then the program output should look something like this:
Start time:1445
End time: 1730
Exactly 2 hour(s) and 45 minute(s) have passed.
Total elapsed time in minutes:165
Total elapsed time in hours:2.75
ElapsedTimeCalculator Class Specifications:
1.Your class will have a constructor that takes two parameters: the starting time and the ending time in military format
2.Your class will also have these methods:
-Get method to return the starting and ending times
-Set method that resets the starting and ending times to values passed as parameters
-a method that returns the hour portion of the elapsed time
-a method that returns the minute portion of the elapsed time
-a method that returns the total elapsed time in minutes
-a method that returns the total elapsed time in hours
Now here below you can see what I have so far...
public class ElapsedTimeCalculator {
private int startTime, endTime;
private int hours;
private int minutes;
private int seconds;
//constructor
ElapsedTimeCalculator(int start, int end)
[Code] ....
I don't have any errors so far, I am more stuck on how to begin a method that returns the hour, minute, etc.. (the third bullet).

I am trying to write to an output file that the user names. I have flushed and closed the printwriter, so now I am at a loss. The console output works fine with the formatting, and the file is created, but I cannot get the file to populate. I have the following:
public static void main(String[] args) {
try
{
Scanner kb = new Scanner(System.in);
System.out.print("Input file: ");
String inputFileName = kb.next();
System.out.print("Output file: ");
String outputFileName = kb.next();
// Construct the Scanner and PrintWriter objects for reading and writing
File inputFile = new File(inputFileName);
Scanner in = new Scanner(inputFile);
PrintWriter out = new PrintWriter(outputFileName);

I have a list of Tabs which are dynamic depending on how many cars are in a database. If there are 10 cars there will be 10 tabs called car 1, car 2, car 3, etc. Each tab simply displays a photo and details of the car.
I have a JMenuItem that says start SlideShow and end SlideShow
What i would like to do is automatically slide through tabs when the start Slideshow is clicked.

Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)
//add button clicked
private class BtnAddActionListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
((DefaultTableModel)table.getModel()).addRow(new Object[]{
cbMonth.getSelectedItem() + "/" + txtDay.getText() + "/" + cbYear.getSelectedItem(),
cbCategory.getSelectedItem(),
[Code] .....
So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.

Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner;
public class ShoutAndWhisper
{
public static void main(String[] args)
{
Scanner scannerObject = new Scanner (System.in);
System.out.println("Enter the text: ");
scannerObject.next();
System.out.println("The text in all upper case is: ");
