try{
BufferedReader breader=new BufferedReader(new InputStreamReader(System.in));
String days[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
java.util.Date date = new java.util.Date(); java.sql.Time cur_time = new java.sql.Time(date.getTime());
/*this is my database connectivity code from where I am getting second date that I am comparing. This is right. Don't bother it.
Connection c= ConnectionManager.getConnection(); String sql = "select t from datesheet where subjectCode=? and sessional=? and d=?"; PreparedStatement ps = c.prepareStatement(sql); ps.setString(1,subjectCode); ps.setString(2,sessional); ps.setDate(3,cur_date); ResultSet rs = ps.executeQuery();*/ if(rs.next()) { java.sql.Time t = rs.getTime("t"); long diff = cur_time.getTime()-t.getTime(); }
Then I am converting it to seconds, minutes and hours, but the problem is time that we get from cur_time.getTime() has more digits than time that we get from t.getTime(), so it is always greater than t.getTime() even when it is not.
long seconds = (diff/1000)%60; long minutes = (diff/60000)%60; long hours = (diff/(60*60*1000))%24;
So I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
I am trying to run a class with a client code and I get the following error
The method add(TimeSpan) is undefined for the type TEST
Why i get this error?
package timespan; // Represents a time span of hours and minutes elapsed. // Class invariant: minutes < 60 public class TimeSpan { private int hours; private int minutes;
I have written a program student record system but can not save data to view or submit record. Able to run the program but failed to submit record or view pre-submitted records.
Prompt for the project is "Write a program that will ask the user for a number of seconds and output the equivalent period of time in days, hours, minutes, and seconds.The program should:
-Use modulo division to calculate the number of days, hours, and minutes. -Use compound operators when making assignments. -Proper formatting and use of comments -Symbolic constants defined as the number of seconds in a minute, hour, and day.
For example: final int sec_in_min = 60;"
public class Mod1 { public static void main (String[] args) { int sec, min, hr, day; final int SEC_IN_MIN = 60; final int SEC_IN_HR = 60 * 60; final int SEC_IN_DAY = 60 * 60 * 24;
I am working on trying to show the average daily sales for the store. I cannot quite figure out why my calculation is not working. Everything works except my average sales is always $0.00... lines 185-189 is where my calculation is located.
Java Code:

I've created several methods in another class to perform certain matrix calculations. Do I need to have mutator method in this calculation class to define the column length of the matrix object? I understand why the following code is not working, but I was hoping to get a quick and easy workaround. I'm not sure how to initialize the size of the column for newMatrix within the method.
public int [][] sum(int matrixOne[][], int matrixTwo[][]) { int sumMatrix [][] = new int[matrixOne.length]["WHAT TO PUT HERE"]; for (int i = 0; i < matrixOne.length; i++) { for (int j = 0; j < matrixOne[i].length; j++) { sumMatrix[i][j] = matrixOne[i][j] + matrixTwo[i][j]; System.out.println("matrixSum" + sumMatrix[i][j]); } } return sumMatrix; }
Then I will use this method to print the new matrix:
public void printMatrix(int newMatrix [][]) { for (int i = 0; i < newMatrix.length; i++) { for (int j = 0; j < newMatrix[i].length; j++) { System.out.print(newMatrix[i][j] + " "); } System.out.println(""); } }
Is all of this overkill and should I just define all the methods within the same class to avoid these issues?
Hospital management system in java. I have designed Hospital, Doctor, Patient, Appointment classes. I am able to add doctor list and patient list and show the doctor list and patient list. How to take new appointment from a patient and assign it to a particular doctor and how to generate a report for inpatient and outpatient on a daily basis.
why my code isn't working. I have to make it so that any time over 40 hours results in time and a half (1.5). Whenever I run the code, it makes it as if EVERY hour is time and a half when it shouldn't be.
import java.util.*; public class lab3 { public static void main(String []args) { double grosspay, pay, hours, federal, fica, state, totaltaxes, netpay; Scanner input=new Scanner(System.in); System.out.println(""); System.out.print("Enter Your Hours Worked: "); hours=input.nextDouble(); System.out.print("Enter Your Pay Rate: "); pay=input.nextDouble();
Basically I need to increase the hours of an employee at the given index. Index is the position of the employee in the array, and amount is how many hours you will be increasing by.

So I have two related tables - Country (Master) Projects (Detail). Country has a OneToMany relationship with Projects. I put a link on my AllProjects.xhtml page. When tyhe link is clicked it uses a data model class to to display the current (clicked) project record (projectRecord object). After editing all the details, the UPDATE button calls a merge method in the DAO class. On the first attempt to update, nothing happens and the record is returned as it is with no errors. If I try updating again, I get:
Is the 'new' keyword in the entity class causing the Inser statement in the DAO because the JPA thinks I want to create a new object therefore invokes INSERT instead of UPDATE?
I am working on web project in java. i have taken buttons in column..and projects is my column..when i click on a button in first row ,i want fetch all information about selected project....so how can i do that?
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub String delete = ("DELETE FROM anagrafica WHERE Nome = ?

and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.
if (addrecord == true){System.out.printnl("record added");}
I close the interface then enter search for the record i just added using add record method but i do not find it what i am trying to say the added record using my application is not there. The question is how to save this record in the database ...
I am running this method but for some reason I am not able to find the data record, it keeps going to the catch. I have the data.txt file in the same directory as the java file.
public static Games[] gamesRecord(){ Games[] game = new Games[50]; try{ Scanner dataFile = new Scanner(new File("data.txt")); for(int i = 0; i > 50; i++){ game[i].title = dataFile.next(); game[i].releaseDate = dataFile.nextInt(); game[i].redistributions = dataFile.nextInt(); game[i].platformRelease = dataFile.next();
In my java web jsf seam jboss application, I want to add a row in a table with some data fields such as date type, String etc, but one field will be a word attachment, how to do it?
Basically, there is a loop to create some rows of data in a table, before each table row data creation, I will create a word file and saved to a local path(the physical file path is hardcoded), then I will create a table row and attach this word file to that row. the loop will continue until the end of loop.
I'm making a game to teach myself programming java so I can start making android. I have this game I'm making where there will be objects(so far its asteroids) will be falling with a progressive velocity (they will move faster as time goes on). The object is the click on the objects before they hit the bottom. It's still early meaning not all the parts I want to implement are there but it works the way I want it to so far besides my click function.
I'm using the Mouse.isButtonDown(0) to record left click but It lets me hold it down and hover over them instead of clicking on each one. Here is a snippet of the part of the code im talking about :
I uploaded a .jar and a exe file so you can see what I mean [URL] .... -jar [URL] .... -exe
public void update(GameContainer gc, int d) throws SlickException { posX = Mouse.getX(); posY = (Mouse.getY()-height)*-1; timePassed += d; deltaTime= deltaTime();
I want an app that I can use to save the name, address, item sold, subject discussed and date that I visited someone - in a job similar to a sales rep. I would like to be able to choose how to sort the info so that if I sort by date I can see who hasn't been visited for the longest and start there. If I think of someone's name then of course I want to sort by name.
One of my friends says he works with "php"[? I'm still learning these terms] and everything happens online. I would like it to be an android app so it can be done without an internet connection ....
