Looping And Month Printing
Oct 4, 2014
Im working on an assignment with the following instructions:
Create a Date class with the following capabilities:
a)Output the date in multiple formats such as
MM/DD/YYYY
June 14, 1992
b )Use overloaded constructors to create Date objects initialized with dates of the formats in part a).
You should only have 3 member data: integer month, integer day, and integer year. Also, you should have at least 2 constructors and 2 methods in your Date.java.

I've been working on a question using parallel arrays where the user inputs an integer 1-12 and the output will be the name of the month and the number of days in that month. This is what I have so far
import java.util.*;
public class DaysMonth
{
public static void main (String args[]) {
Scanner keyIn = new Scanner(System.in);
int[] days = new int[]{31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
[Code] ....
After I enter the user int it just ends.

I have written program for rainfall that will store and give total, average, least and most. The program stores the input of rainfall for each month. However at the end it suppose to print out the month with the least and most rainfall. I am getting this on the print for
The month with the most rainfall: [Ljava.lang.String;@79a7bd3b
and for
The month with the least rainfall: [D@7378aae2[Ljava.lang.String;@79a7bd3b
. What have i done wrong?

I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.

I have Georgian Calendar object
GregorianCalendar date = (GregorianCalendar)pageContext.getAttribute("datetime");
System.out.println("date :::: "+date);
It prints :
date :::: java.util.GregorianCalendar[time=1408045500000,areFieldsSet=true,
areAllFieldsSet=true,lenient=false,zone=sun.util.calendar.ZoneInfo[id="GMT+05:30",
offset=19800000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],
firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2014,MONTH=7,
[Code] ....
I want month and year from this like August 2014. How can i do the same.

I'm working on a program that prompts the user to enter the year and first day of the year and displays the calendar table for that year on the console. For example, if the user entered the year 2005, and 6 for Saturday, Juanuary,1, 2005, the program should then display the calendar for each month of the year.
I have written the program and solved the problem for the most part. Only, I'm having terrific difficulty getting the output to properly format. I'm *almost* there. I'll post my program below and then output.
import java.util.Scanner;
public class DisplayCalendar {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter the year: ");
int year = scanner.nextInt();
[Code] ....

looping through 2d arrays.
This code works when printing '*' to show the number of elements in a 2d array:
static int [][] gameboard = new int[3][7];
for (int i = 0; i < gameboard.length ; i++) {
for (int j = 0; j < gameboard[0].length ; j++) {
System.out.print("*");
Thread.sleep(1000);
but then this does not:
static int [][] gameboard = new int[3][7];
for (int i = 0; i < gameboard.length ; i++) {
for (int j = 0; j < gameboard[i].length ; j++) {
System.out.print("*");
Thread.sleep(1000);
The difference is on the third line where i did gameboard[i] instead of gameboard[0]. I get a runtime error on the second one.

I have an assignment where I'm supposed to write a program where the user inputs a month between 1-12 and then the right amount number in every month. I've tweaked the code a bunch of times, but I keep getting this error message:
insert "}" to complete StatementKALENDER_3.java
insert "}" to complete BlockKALENDER_3.java
The code:
import java.util.*;
import java.util.Scanner;
public class KALENDER_3
}
public static void main(String[] args){
Scanner scanner = new Scanner (System.in);
System.out.print("Skriv ett manadsnummer: ");
[code].....
I think I have just forgot to put in a few { } symbols, maybe an open loop?

Write a program that asks the user for the low and high integer in a range of integers. The program then asks the user for integers to be added up. The program computes two sums:
The sum of integers that are in the range (inclusive), and the sum of integers that are outside of the range. The user signals the end of input with a 0.
Your output should look like this:
Sample input/output
In-range Adder Low end of range: 20
High end of range: 50
Enter data: 21
Enter data: 60
Enter data: 49
Enter data: 30
Enter data: 91
Enter data: 0
Sum of in range values: 100
Sum of out of range values: 151
This is my assignment and below is my code.
import java.util.Scanner;
class InRangeAdder {
public static void main(String[] args) {
Scanner scan = new Scanner (System.in);
int low, high, data=1, rangesum=0, outrangesum=0;
[Code] ....
The problem is that the program simply gives an output of 0 for both "rangesum" and "outrangesum". I don't quite understand why that is. Also i have a quick question, the program needs me to end the program when the value of data is 0 but in order to initialize it I need to give it a value. Usually I would give it a value of 0 like I have for rangesum and outrangesum but if I do the program does not run till the loop as it considers the value of data to be 0 and ends the program right away. What would be a work around to this and when do I need to have a value to initialize an integer? for example, I do not need a value for low and high. Is this because the program recognizes that a value is going to be defined but cannot do that for the other integers as they are inside a loop?

I have a program ive been working on and it works, but the flags in the runnables seem to shift the output down 1. for instance i commented playa3. start(); to see whats going on, if i just run playa1 i got no issues, as soon as i enable playa2, i get this output:
Game continues...
Dealer places King and Queen on the table.
Game continues...
Dealer places Queen and Ace on the table.
Player one with 'Ace' places his card on the table.
Player one with 'Ace' wins the current deal.
King Queen
Game continues...
Dealer places Queen and King on the table.
Player two with 'King' places his card on the table.
Player two with 'King' wins the current deal.
Queen Ace
the second time the dealer deals, player one places his cards on the table when he was supposed to do that for the first deal which he didnt. the last line there, (king queen) is just a print statement that is referring to the dealers hand that, that iteration is responding too. below is my code, i
import java.util.*;
import java.io.*;
import java.lang.*;
public class P5
{
public static int i, count, dealerFirstCard, dealerSecondCard, player1, player2, player3;
public static String cardSet [] = {"Ace","King", "Queen"};
public static volatile boolean dealerFinished= false;
public static volatile boolean playersFinished= false;

I'm having some issues, trying to solve this problem in java. I want to print some election results, and i have to loop through a vector of objects and retrieve the partial sums of each party's seats for each constituency and the national results for each party. For now i can print the results per contituency, but i'm having problems in getting the national results. Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.
This is what i have.
Java Code:
while (i < h.geral.size()) {
show += "Constituency - "
+ ((Party) h.geral.elementAt(i)).getConstituency() + "

int x = 10;
do{
System.out.print("value of x : " + x );
x++;
System.out.print("");
}while( x + x == 22 );
When i put x+x==22 than it gives 2 values of x which are 10 and 11, they are wrong but when i put any other value like x+x==24 it just shows 1 value which is 10. I am not able to understand what mistake is there. I have been searching it for past whole month but didn't got any reason.

The player is defined as having 8 attributes which are in the array. The user enter attribute ratings that are restricted between 1 and 10. The total number of attribute points per player to allocate is 60. So my checks are that the inputted numbers are between 1 and 10 and the sum of them is 60. I continue to get an infinite loop when the code hits the if statement defining jamesTotalQuarter != 60. The code works however if the total is 60. What I want it to do is if the total != 60 revert back to the top of the code to allow the user to re-input their ratings. I've tried different combinations of continue and break statements without the outcome I'm looking for.
[public static void lebronJames() {
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
//Declare an array to hold 8 intgers values
int lebronJamesAttributes[] = new int[8];
int attribute = 0;
System.out.println("Please allocate your attribute points for Lebron James in the following order. Your point allocations per attribute should be between 1 and 10. You have a total of 60 points to allocate");
System.out.println("-----------------");
System.out.println("Close Range" + "

I have written a small program that creates a loop that only fails to continue once we reach a StackOverflowError exception. It looks just like:
class MyFirstApp {
static int counter;
public static void main(String[] args) {
counter++;
System.out.println(counter + " in main.");
roundAbout();
}
public static void roundAbout() {
counter++;
System.out.println(counter + " in roundAbout.");
main( new String[0] );
}
}
The idea of the program is to go between each method without using an object. Each time the method is entered the static int counter variable is incremented and outputted along with its respective loop. The loop does, however, fail eventually.
By calling the between the methods we build a tower of stack frames that eventually topples. The number of times this runs before the StackOverflowError occurs varies, though. Sometimes I get 6553, 6554 or something else close to these values.
Is there a way to pop a method of the stack or clear part of the stack so I can keep this going? I don't know where I would use this but it would be nice to know.

I have to create a method to find the current month with the input being a number of milliseconds using System.currentTimeMillis(). Now I was able to solve the problem with the following extremely cumbersome method:
public static int monthLeap(long ms) {
int result = 0;
int jan = 31, mar = 31, may = 31, jul = 31, aug = 31, oct = 31, dec = 31;
int apr = 30, jun = 30, sep = 30, nov = 30;
int feb = 28;
int febLeap = 29;
[Code] ....
I first go through a loop that goes through all the years and subtracting the number of days of a normal year or a leap year in milliseconds from the total milliseconds. At the end I should have a rest value of milliseconds that represents the amount of milliseconds that have passed already this year. Out of this number I then find the month we are currently in.
My problem is that the above method is way to large and I get a checkstyle warning: "NPath Complexity is 12,288 (max allowed is 80)".
I know that this can somehow be solved with a for loop iterating through the time and counting up months until there is no more month left. My problem though is the different lengths of the months. If each month was the same I could just subtract the amount of days in each month from the rest value.
(Since I already got it down to <= 12 months, I shouldnt bother with the extra days to find the month. Yet if I want to find the month when the date is the first or last day of the month it is important to be very precise) ....

I'm making a program to handle temperature conversion. All the math is working properly, but I'm having trouble with making a loop to not let the user proceed until a valid input is given. The expected input is a double, then a space (though I found using enter works as well), then a char to represent Fahrenheit or Celsius. If I run this piece of code in the entire program with proper input, it works. When I use an invalid input, the catch works, and the code loops, but then the user isn't allowed to enter a new input, so thirdTester stays as equal to 2, so the loop repeats indefinitely.
do{
try{
System.out.println("Enter the temperature (example: 98.35 F).");
temperature = keyboard.nextDouble();
unit = (keyboard.next().charAt(0));

I have created an enumerated data type that represents months. In my program I have asked the user for the month. I hold the month entered by user into a string variable. From that string variable I'm trying to display the month using my enumerated data type. I know I can use if statements, but is there another simple way to do it?
import java.util.Scanner;
public class demo {
//Enum class called month that has constants in it representing months

I am working on my second javafx program and I am getting confused. The program that I am writing is a payroll calculator. A secondary window opens at the start of the program where the user first enters the number of employees and clicks submit to save the number and to close this window. Then, the user begins to enters the employee information (first name, last name, pay rate and hours worked) when the user clicks the NextEmp button, I want the data in the text fields to be entered into arrays for later use, then clear the fields for the next use. I am running into 2 issues. The first is the close event for the secondary window that pops up. I cannot figure out the syntax. The second issue that I am running into is the loop to store the data into the arrays. I believe I am getting the text field data correctly, but I cannot figure out how to stop the loop until the NextEmp button is pressed again.
