Unable To Pull Out Lowest Week Number In Program
Apr 29, 2014
This program reads off of a text file that I have attached to my post. It is supposed to:
display the total sales for each week
the average daily sales for each week
the total sales for all of the weeks
the average weekly sales
the week number that had the highest amount of sales
the week number that had the lowest amount of sales
I can get everything but the very last one. In my code you will see that I tried to use a really large number so it would pull out the lowest amount, but it still didn't work: low = 100000000;
SalesData.txt (173bytes)
Number of downloads: 29

Why does setting the first day of week to Sunday changes week number? This piece of code
public static void main(String[] args) throws Exception {
System.out.println(System.getProperty("java.runtime.name") + " " +
System.getProperty("java.runtime.version"));

I am not getting the result I am looking for, but I'm sure I'm on the right track. I have an array, names + times of marathon runners, and should end up with a program that displays the slowest runner, and the next-slowest runner.
Currently, I get this:
The lowest time is 273.
The lowest time is 243.
Changing names.length to times.length changes nothing.
for (i = 1;... ) changes nothing.
The displayed number should currently only be 243. Why is it displaying 273 first, and at all?
The code:
class Marathon {
public static void main (String[] arguments) {
String[] names = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil", "Matt", "Alex", "Emma", "John", "James", "Jane", "Emily", "Daniel", "Neda", "Aaron", "Kate"};
int[] times = {341, 273, 278, 329, 445, 402, 388, 275, 243, 334, 412, 393, 299, 343, 317, 265};
int min = times [0];
for (int i = 0; i < times.length; i++) {
if (times[i] < min){
min = times[i];
System.out.println("The lowest time is " + min +".");
}

I've been trying to pull data from another class file "Calculations.java" and have it be displayed in a TextField in "DataAnalyzerGUI.java". Here is how the hierarchy is broken down for my assignment:
DataAnalyzerGUI.java extends JFrame
ReadFiles.java extends DataAnalyzerGUI.java
Calculations.java extends ReadFiles.java
Everything displays and functions correctly in a command prompt if I use a line like this:
System.out.println ("Lowest opening " + dateArray[lowestOpenIndex] + ": " + dataArray[lowestOpenIndex][2]);
But trying to get it to display in a GUI has been quite troubling.
I know the code is supposed to look something like this:
dataOutput.setText(DESIRED CODE HERE);
But I am unable to find anything of value to work out.
I have attached my complete project....

I'm trying to print out the results of a program that calculates the number of seats the parties will get in an election.I have to print the partial results and the national results.
I can print te number of seats per party in each constituency, but how can i sum all seats per party in each constituency and print the national results?I'm working with vectors, which I know it might not be the best option, but everything is working, except the fact that I can't loop throuhg the vector and retrieve the total sum per party.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.Is it possible, or doIhave to create a method in Parties class to solve the problem?
This is what I have now.
for (Parties p : h.geral) {
show += String.format("Constituency - %5s - %5s - %d%n",
p.getConstituency(), p.getParty(), p.getNum_seats());
}

I have to find the average, highest, and lowest numbers in an array. I already have the average and highest, and I thought I could find the lowest number the same way I found the highest, but it's not working. It just keeps coming out to 0. I've tried out different ways, but I want to see if there are better ways than doing MAX_VALUE for the lowest, then looping it through.
import java.util.Scanner;
public class Test_Scores {
public static void main(String[] args) {
//array,scanner,values

1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.

I'm quite new in android programming and I've meet some problem in push and pull method. I have created 2 activity in my app 1 of them call Push_activity and Pull activity(Code are shown below). The String that I keyed in PushActivity have to "transfer" to the PullActivity when the button is pressed:
PullActivity
but1 = (Button)findViewById(R.id.buttonll);
tx = (TextView)findViewById(R.id.editText1);
tx.setText(getIntent().getStringExtra("extra"));
but1.setonclickListener(new onclickListener(){
[Code] ....
The app works fine when it started. When I press the button in PushActivity, it crashed and the error came from my textview in PullActivity.

I'm unable to get the output for "AverageDriver" to print correctly(5 scores in descending order and average). The output displays the scores the same way they are entered and the average is always zero. The output for the Average program works fine and with the correct output.

import java.util.Random;
public class Karakterbok {
public static void main(String[] args) {

I need to create a simple Java program that calculates the difference between two entered days of the week with the following requirements:
-Ask the user to enter in a day of the week by name (e.g. Monday)
- Ask the user to enter in another day of the week by name (e.g. Friday)
- Create a static method other than main that takes in two Strings as input, and returns an integer value equal to the difference between the two days
- Use an array with the days of the week in it to find each entered in day of the week, and use their indices to calculate the difference
- Output the difference for the user to see

I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h
My guess is too high?
My fifth guess is 16: h
*** I am unlucky this round. I give up.
Let's play!
My first guess is 10:
etc..
import java.util.*;
import java.lang.Math;
public class numguessprac1 {
// Declaring variables
public static String input;
public static int quit;
public static int guess;
public static int wins;

Here is what I'm trying to do using arrays.
gather sales amount for the week
display the total of sales
display the average of sale
display the highest sale amount
display the lowest sale amount
using occurrences determine how many times the amount occurred for the week
make a sales main
make a sales data
This is what i have so far but I'm confused on how to start the occurrence and where it would be placed in order to get the information from the array
public class SalesData {
private double[] sales; // The sales data
/**
The constructor copies the elements in an array to the sales array.
@param s The array to copy.

Having just started college, Bob has been busy looking for a part-time job to fund his new college social life and after only two weeks of looking he has managed to get two job offers! Each job comes with different hours, basic rates of pay and over-time rates so he needs to work out which would get him the most money.
Develop an application that would allow Bob to enter his basic pay rate, his number of regular hours work per week and his number of overtime hours per week. The application should then calculate and display Bobs total basic pay for the week, his overtime pay for the week and his total pay including overtime.
Your application should use instantiable classes to separate the calculations from the user input and output.
Save the instantiable class as Pay.java
Note: The overtime rate is 1.5 times the basic rate of pay
This is my instantiable class code which compiles correctly
public class Pay{
//Declare Data members/Variables
private double pay;
private double hours;
private double overtime;
private double totalBasicPay;
[Code] .....
My errors in the second bit of code that i have never seen before
"C:UsersAndreDownloadsPayApp.java:25: error: no suitable method found for println(<null>,String)
System.out.println(null,"Please enter Basic Pay");
^
method PrintStream.println() is not applicable
(actual and formal argument lists differ in length)

I am developing a java swing application. In which i want to set a different text to a label in same program ( in single JFrame). I dont want to use another JFrame instead i want to use setText method of java and set different text to a label at different intervals of time according to my need.
I am using java 1.7 sdk and pupy linux as OS. Below i am giving source code.
What i am doing is in constructor of class i am setting an image to JFrame and setting text "Welcom...". And when user clicks on this JFrame a method is called which will clear the text "Welcome.." and sets new text to another label "Enter...." and from there another method is called and it clears label "Enter..." and sets a text "Plzz wait..". and yet there are more methods, i havnt provided here.
But what is happening is it shows welcome text and then directly Plzz wait..
Its not showing text Enter... because control is finished after last method gets executed.
My concern is i want to show all the setText (my messages) in a sequence. Without using another JFrame. There is no any user input other than user will click on first welcome page.
public class BackgroundFrame extends javax.swing.JFrame {
JLabel setTitle1;
JLabel setTitle2;
JLabel setTitle3;
JLabel setTitle4;

I am trying to create a program for class the uses two dimensional arrays. I am stuck on the second step that states Use two parallel arrays. One is a two-dimensional array -- a row of this array will hold six values in this order: [0] number of hours worked, [1] hourly pay rate, [2] gross pay, [3] net pay, [4] federal withholding, and [5] state withholding.
This is what I have so far:
Java Code:
double [][] data = new double [30][6];
String [] names = new String [30];
String str = null;
String detail = null;
int n = input(data, names, inputFile); mh_sh_highlight_all('java');
(there's more but i don't believe it pertains to this question)
My question is how would I create this array. Or, is that right above? I've searched online and in my book and I just don't understand.
