Create Program That Prints Time Between 00:00 (0:00 Am) And 23:45 (11:45 Pm)
Feb 8, 2014
I was told to create a program that prints the time between 00:00 (0:00 a.m.) and 23:45 (11:45 p.m.) in the 24-hour clock and 12-hour clock format like this:
24-hour Clock 12-hour Clock
-----------------------------
00:00 0:00 a.m.
00:15 0:15 a.m.
00:30 0:30 a.m.
00:45 0:45 a.m.
01:00 1:00 a.m.
01:15 1:15 a.m.
01:30 1:30 a.m.
01:45 1:45 a.m.
02:00 2:00 a.m.
ect...
but cant seem to create the program and my program doesnt seem to run.

I need to add Logger function in the catch block that prints time, date and description of the what had happened.
public class InputUtil {
public static final String[] SPECIAL_CHARACTERS = { "!", "#","%", "^", "=",
"+", ";", "[", "]", "|", "<", ">", "?", "~", "`", "-", "" };
public static String deleteSpecialCharacters(String inputString) {
String outputString = inputString;

I'm trying to create a circular array which prints out 8 numbers that increase by one and don't exceed 9. If they do, the remaining numbers are printed from 0 on-wards. I have code below which does this job, but it doesn't really use an array to loop back.
Java Code:
package Practice;
public class Practice
{
public static void main(String[] test)
{
number(7);
number(9);
[code]...

I have to make two classes. The first one crates an instance of an array of several integers and prints data (average, greatest, lowest, et cetera) based on the second class, which contains the methods. I'm having a problem with the syntax for the first class required to use the methods.
Here's a shortened version of what I have right now just based on processing the number of integers in the array (because if I can get just one method properly connected, I could figure out everything else).
Driver
import java.util.Arrays;
public class ArrayMethodsDriver
{
//Creates the ArrayMethods object
public static void main(String[] args)
{
int[] a = {7,8,8,3,4,9,8,7};
[Code] ....
When I try to compile this, I currently get the "class expected" error on the count part.

When I run this code, it is supposed to get one value from turnTimer(); and return it, just as a test. This works when I enter a valid pit. For example. If I were to input "A" when it's player one's turn, it will return 1, like it should. However, if I were to type "H" when it's player one's turn, it returns "Not a valid pit!"(like it should) but then it also returns 12. It shouldn't know that H is 12 because it's in a separate method. I'm confused as to why it's printing both values.
import java.util.*;
public class Mancala {
static Scanner input = new Scanner(System.in);
public static int pit;
public static void main(String[]args) {
Mancala mancala = new Mancala();
int[] board = {0,3,3,3,3,3,3,0,3,3,3,3,3,3};
[Code] .....

So I'm trying to write a program that prints out the "most-repeated integer" in an Array.
For example: if an array contains {1,2,2,3} It would print out 2 as the result.This is what I got so far and according to my knowledge I think I'm correct but for some reason it doesn't work.. Please give me some inputs.
public class MostInt{
public MostInt (){
int[] array = {0};
for(int i = 0;i>array.length;i++){
if(i==i++){
System.out.println(i);

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.
import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

Write a program that asks the user for an integer andthen prints out all its factors in increasing order. Use a class FactorGenerator with a constructor FactorGenerator(int numberToFactor) and methods nextFactor and hasMoreFactors. Supply a class FactorTester whose main methods reads a user input, constructs a FactorGenerator object and prints the factors.
Here is what I have so far for my main class and tester class
public class FactorGenerator
{
int factor;
int number;
int x;
FactorGenerator(int numberToFactor)
{
number = numberToFactor;
}

I am having trouble with methods. What I want to do is be able to create 4 types of strings under the same method, but only draw one of them at a time.
i.e
UI.initialise;
UI.addButton ("pipe", this::drain);
public void drain(){
this.pipe ("pipe1");
this.pipe ("pipe2");
[Code] ....
When I press the button "drain" it will print=
pipe1
pipe2
pipe3
pipe4
I am having a lot of difficulty just printing one out after each time I press drain.
"drain"
pipe1
"drain"
pipe2 etc..

I'm trying to create a server which sends the clients connected to it its local time. Looking at a few tutorials I've managed to connect the clients to the server, but can't send data to the clients. I've successfully done easier examples, without threading. I guess the problem might be im me not knowing what exceptions are for.
Client: When running the code "AAAAAAA" does execute but "BBBB" doesn't, so I guess the problem should be in fraseRecibida = entradaDesdeServidor.readLine();
import java.io.*;
import java.net.*;
import java.util.Scanner;
public class Client {
public static void main(String[] args) throws Exception{
String fraseRecibida;
[code]....
I don't understand the exceptions, maybe I should give them a look before continuing with sockets. Being frank I'm not really sure why the while(true) is there.
import java.io.*;
import java.net.*;
import java.util.Calendar;
public class ServerThread extends Thread{
Socket socket;
ServerThread(Socket socket){
this.socket = socket;

So, here is the question I have been working on: Write a java class named Time that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example the elapsed time is 9630 seconds, and then the output is 2:40:30 ).Hint: an hour has 3600 seconds and a minute has 60 seconds. Use Scanner class for reading the input.
Here is my code:
import java.util.Scanner;
public class Time {
public static void main(String[] args) {
Scanner scan= new Scanner(System.in);
System.out.println("Enter the elapsed time in seconds:");
int totalseconds= scan.nextInt();
[Code] .....
Now, I know I am supposed to use the remainder operator to figure out the time in minutes and seconds, but the hours has be a little confused. Right now this code compiles but gives me an exception.

What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.
However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:
-year:<year(s)>
-rank:<rank(s)>
-artist:<artist>
-title:<title>
-sortBy:<field>
Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.

i am very new to java programming what i am doing wrong here. Write a program that calculates how much an employee would earn over a period of time (in months), if, every month, the employee’ pay-per-hour rate is one dollar more than the month before (so if his starting perhour rate is 7.25, next month it will be 8.25, next month 9.25, and so on). The employee is going to work 20 hours per week, 4 weeks per month.
The program should input from the user and validate both number of months (which should be a positive integer larger than 0) and the pay-per-hour rate (which should be a floating-point number larger than $7.25 – the minimum federal wage pay-per-hour rate). For each one of these values; if the value is wrong, the program should repetitively ask for that value until the value entered is correct. The program should confirm/output the correct value.
/*
This program calculates how much as employee would earn if every month the employee pay per hour would increase by a dollar

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:
Hours: - Population:
0 ------- 1000
12 ----- 2000
24 ----- 4000
I've created the code, but don't understand how to increment hours by 12 and double the population by 2 each time.
public class Population
{
public static void main (String[] args) {
int hours = 0;
int population;
