JSP :: Convert Minutes To Hours And Minutes Using JSTL And Java
Sep 19, 2014
I'm fairly new to JSTL. Can I convert the minutes JSTL expression into hours and minutes using a java method. I'm not sure how to go about.
<% CalendarUtilities.getHoursAndMinutes(%> ${minutes} <% ) %>

I need to write a simple program that reads an amount of minutes and displays the approximate number of years and days for the minutes. For simplicity, assume a year has 365 days and the resulting amount of days is a whole number.

I want to compare two times. What I am doing is
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;

I have an application which is doing a fine job of placing the total hours on the interface.
Where I am breaking down is that I am unable to split the string into two distinct groups: hours and minutes
private HtmlElement createTravelTimeRow(ShowSet showSet) {
HtmlElement tr = new HtmlElement(ROW_OPEN, ROW_CLOSE);
HtmlElement td = new HtmlElement(CELL_OPEN, CELL_CLOSE);
[Code].....
I came across something which showed how to split the String but I am still very unsure how to do this.

I'm trying to put in a countdown timer into my project, but want to get it working first. I am finding trouble because I have a couple of errors.
Java Code:
package Project;
import java.awt.event.ActionEvent;

public class Minutes {
int count = 30; //Integer count is set equal to 30.
int delay = 1000; // Integer delay is equal to 1000. 1000 being in milliseconds which is 1 second.

I'm using this methodology for Java connection between client and server, the server allows the user to stay connected while it is sending messages, but if you stay an average time of 5 minutes without send anything it is disconnected, I need to increase that time to about 30 minutes or disable this disconnection for inactivity.
Settings:
Netbeans 8.0
Windows Seven 64 Bits Ultimante
The following code:
package redes;
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Font;
import java.awt.event.ActionEvent;

I have a timer where it counts down from 300 to 0 then does something. But I want the display for the clock to show the time in minutes. I tried:
double showTimeLeft = timeLeft / 60;
o.setDisplay(String.format("%.2f", showTimeLeft) + " Minutes");
But Every so many seconds it skips like:
Time = 3.38
Time = 3.37
Time = 3.35
Time = 3.34
It skipped 3.56
How to do this right?

I have a servlet with a method:
/**
* @return <code>double</code> Hours
*/
public double getDriveHours() {
return getAsDouble("DriveTime", 0.0D);
}
I would like to change the time to minutes. I will create a new entry in the db for the minutes, but wondered if the time minutes is also double.

Finding a strategy that allow process 12 millions of records in less than 1 hour. Each record can be modified by business rules. In this process are performed insert, update and select in other 3 tables.
The end result of this process is update monetary fields (for the calculations is used BigDecimal) of records in another table.
This process is part of the migration of Cobol to Java/Oracle. In cobol this process takes approximately one hour. Is it possible?

I am working on an assignment that I can't seem to figure out the final part to. The program takes in course data such as the time the class starts and how long it lasts. The time is in military time (0000 - 2400)
I need the output time to be the time the class started, plus the length of the class, and displayed in military time.
for example,
Start Time = 0930
Length = 50 minutes
Endtime = 1020
I can't for the life of me figure out how to do this. I have gotten a program that works for this time and minutes, and displays the correct 1020. But when I change the information to say
Start time: 0700
Length = 90 minutes
I get:
Endtime = 90
90 is technically correct, the way the formula is setup, but I need it to display 0900 not 90.
Here is the code that I have. Be easy, I'm still learning, and this is just the file I created to get the formula to work. Also, the verbose in here is just for my own debugging to make sure values should be what I'm expecting them to be.
public class calc
{
public static void main(String[] args) {
double hours, minutes, length;
double temp;
int time = 2400;
hours = time / 100;
System.out.println("Hours are: " + hours);

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.
This is what I have so far,
public void increaseHours(int index, double amount){
for(Employee e: employees){
if(e instanceof HourlyEmployee){
HourlyEmployee he = (HourlyEmployee)e
he.increaseHours(amount);
}
}
}
}
I'm not sure how to use the index to do this correctly, all it's doing right now is adding hours to every hourly employee

I need to convert c# function to java method. The important thing is String strKey. Parameters for testing are strMask= 4634958 and strSN=1394901184 and the result must be strKey = 2156325482!!! The result that I am getting with my Java code is 2138641814.This is C# code:
public static bool Key (String strMask, String strSN, ref String strKey)
{
System.UInt16 wLo, wHi;
System.UInt32 dwSNx, dwKey;
System.UInt32 dwSN, dwMask;
if (strMask=="") strMask="0";

I am suppose to have a method called save() which should marshall the list of computer parts in the right panel to an XML file. In reverse, another method called load() that should unmarshall the saved XML file back into an object. So basically, the Save event will call save() method and save the list of parts in the right panel to an XML file. The Load event should clear the right panel, and call load() method. When load() is called, it should display the unmarshalled data in the right panel. I got "Exit" to work.
I'm having hard time figuring out the "Load" and "Save" parts though.
