Program To Store Total Rainfall For Each Of 12 Months Into Array Of Doubles
Oct 26, 2014
"Create a project called RainFall and a class nameD RainFall. Write a program that stores the total rainfall for each of 12 months into an array of doubles. The program should display total rainfall for the year, the average monthly rainfall, the month with the most rain and the month with the least rain. When outputting the month with the most and least rain, output the name of the month. This is what I have so far.
Write a program that stores the total rainfall for each of the 12 months into an array of doubles. The program should have methods that return the following:
The total rainfall for the year The average monthly rainfall The month with the most rain The month with the least rain
I was wondering how can I calculate total age in months and store it as variable? this is what I have so far:
* * You will ask the user to provide their name (as a single word, assume first name here) * You will ask the user their age in full years (no fraction or months) * You will ask the user how many full months since their last birthday (again, whole numbers here). * * You will use this information to calculate the user's age in months and use that information to print out a greeting. */ import java.util.Scanner;
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
In this main class, create 5 objects of the class Menu, as defined in the table below.

Exercise d In your main class create an array of length 5, and store the 5 objects (Exercise c) into the array. You can use any name for your array.
From the array, use a loop to: Print the details of all the objects using the method you defined in Exercise b.
Exercise e Use another loop to: -Print only the name and cooking time of all the dishes that take less than 30 minutes to cook. Hint: you may use the getter methods for the name and cooking time attributes, and then, print these values (name, cooking time).
Exercise f Use another loop to : -Calculate and print the total price of all the objects (in the array). -Calculate the total price of all the objects with VAT included for each dish (VAT rate is 17.5%).
Submission -Create a folder with your index number as its name. -Copy your Java Project folder into the created folder. -Print a hard copy of your classes. -Submit both soft copy and hard copy of your project
i'm trying to write a program that uses an array to store 10 numbers. The numbers should be randomly generated ( Math.random() ), and they should be between 1 and 100 ( 1 and 100 inclusive ). The program should produce an output like the one below:
Element 1 = 23 ( Odd ) Element 2 = 15 ( Odd ) Element 3 = 32 ( Even ) Element 4 - 10 ( Even ) Element 5 - 99 ( Odd ) Element 6 - 1 ( Odd )
[Code]...
I have written code for this but its only showing me 0's after first number can you check whats wrong with my code. my code is.
class even/odd{ public static void main(String[]args){ int y=0; int z=0; int[] array= new int[11]; for(int x=1; x <array.length ; x++){ array[x]= (int) (Math.random()* 100);
public class MonthsName { static String monthsName[]; public static void main(String[] args) { String[] months = new String[13]; months[0] = null ;
[Code] .....
I keep getting 1 error that tells me this. Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at MonthsName.main(MonthsName.java:22) Java Result: 1
Just before that netbeans couldn't find the main class. I was wondering if it netbeans or my code that's wrong.
The main method will drive your program by doing the following:
-Create an array to hold all the individual golfers and par scores (type is Golfer[ ]). -Prompt the user for a data file containing the Par scores and the player names and score. The format of the input file should look like
import java.util.Scanner; public class SophiaKeyProgram1 { public static void main(String[] args) { // TODO Auto-generated method stub int numQuarter; //number of quarters in a year double rainfall=0; //the amount of rain
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 */ package nick.employee; import java.util.Scanner; public class nickemployee {
I'm allowing the user to choose certain items to buy that is moved to an array.Now I'm trying to add those thing in the array use a different class. how I can call the array from my driver class to my checkout class that adds them together.
Write a Java method that returns the largest value of an array of doubles passed to the method as an argument.
Back into java wasn't sure how to do it for doubles did one in the main for integers and then added a method changed from int to double and now i'm lost as go why its not working.
package kickstarter9; public class Kickstarter9 { public static void main(String[] args){ double myList; double[] myList = {6.0, 4.1, 2.4, 6.8, 1.9, 9.4, 2.8, 4.6, 9.3}; // find the largest value in the list
So I need to generate 10 random integers in the range 1-20 but i have to store them in an array called numbers. Then I have to call a method called displayArray which displays the contents of the array and for the assignment i have to use a for loop to traverse the array. The method header for the displayArray method is:
public static void displayArray(int[] array)
This is what I have done
public class RandomIntegers { static int numbers = 0; public static void displayArray(int[] array) { System.out.println(numbers + "Numbers Generated");
I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner; import java.text.DecimalFormat; public class PenniesForPay { public static void main(String[] args) { int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?
I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder; import javax.swing.*; public class UseOrder { /** * @param args the command line arguments */ public static void main(String[] args) { Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?
You have been given the job of writing a program to assist pilots who fly the Beechcraft Starship-‐‑1 executive aircraft.As with any airplane, it is essential that the pilot know the total weight of the loaded plane at takeoff and its center of gravity. If the plane weighs too much, it won'ʹt be able to lift off. If the center of gravity is outside the limits established for the plane, it might be impossible to control. Your task is to write a program that will determine the total weight and center of gravity of this plane
Inputs: The number of crew members, number of passengers, weight of the forward baggage compartment contents, aft baggage compartment contents weight, and the amount of fuel in gallons are to be accepted as INTEGER values in the order stated. Be sure the input values are within acceptable ranges
Outputs:You must echo the input values, annotated with their appropriate names,calculate and display the total weight, and the center of gravity.
So I've attempted a for loop for this type of problem:If you receive $0.01 on the first day of your allowance, and the daily rate doubles each day after, calculate the total earnings for 30 days.
Output should be like: Day ----- Daily allowance - Total allowance 1 -------- 0.01 -------------- 0.01 2 -------- 0.02 -------------- 0.03 3 -------- 0.04 -------------- 0.07
My code so far:
public class Allowance { public static void main (String[] args) { int day = 0; double daily = 0.0; double total = 0.1; System.out.println("Day Daily Allowance Total Allowance"); for(day = 0; day <= 30; )
i have a program that is to store DVD information and when i enter all the information asked it returns no info. I have a DVD inventory file and a DVD extended file.

Here is my problem: if I want to add a number of X consecutive values in an array and get the minimal total value along with the indexes that caused this result, how can I do that?
For example:
X = 2 array[4] = (5,2,8,6,7)
start adding every 2 consecutive values as following:
Recently I have missed a few weeks of my class due to family emergencies. Because of this I have missed very important lectures. My professor has assigned me the following assignment:
Prices Write a Java program that specifies three one-dimensional arrays names price, amount, and total. Each array should be capable of holding 10 elements. Using a loop, input values for the price and amount arrays. The entries in the total array should be the product of the corresponding values in the price and amount arrays. After all the data have been entered, display the following output:
Total Price Amount
==== ==== ======
Under each column heading display the appropriate value.
I know how to display everything using printf, how to create the actual arrays and define the array size, but I am confused on how and what loop to use and how to construct it. This is what I have managed to write up so far:
import java.util.Scanner; // Imports the Scanner class import java.text.DecimalFormat; // Imports the DecimalFormat class
public class Prices { public static void main(String [] args) { double[] price = new double[10]; double[] amount = new double[10]; double[] total = new double[10];
// Create a new Scanner object Scanner keyboard = new Scanner(System.in); } //End of main method } // End of public class
How could I store the currency and amount in an array? A 2x2 array would do this but how to store them and retrieve them is the challenge. For example, I have a method that asks the user for two inputs, the currency and the amount and using the array as a chat table where I could map the currency to the the currency input entered by the user, I could do some calculations with the amount entered by the user. how I could represent the 2x2 array?
I have a file called statecapitals.txt that is read in, I want to store it in either a 2d array or hashmap and select a random state then Ask the user for the name of the capital. Then I want to Let them know if they are correct or not and have a choice to play as many times as they like. When they no longer want to play,I want to let them know how many they got correct and how many incorrect. I am not sure which would be better a hash map or 2d array and dont know where to start with each.
here is what the text file looks like:
Alabama - Montgomery Alaska - Juneau Arizona - Phoenix Arkansas - Little Rock California - Sacramento Colorado - Denver
Code below. I am not sure if my logic is correct. I want to prompt a user to enter registration numbers from 100 to 1000, store the numbers in an array then sort them.
import java.util.Scanner; class regnumber { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("registration number ", 100,1000);
What is printed is much larger than what I've copy and pasted but I can't post it all here.
The error I get is:
Exception in thread "main" java.io.IOException: Stream closed at java.io.BufferedReader.ensureOpen(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at Map.importMap(Map.java:26) at Map.main(Map.java:44)
So i wanted to try something new like find an image within an image. So for my "find" method I would like to take an image and use it to scan and compare sum of absolute differences with the bigger image. So that the smallest SAD would be the exact image that I am using to scan. What I am thinking is to put each pixel value of both images into two separate arrays and compare them via Math.abs(image1[i][j]-image2[i][j]); . My only problem is that I do not know how to put each pixel value into an array.
Also, If I only want to compare just the green in the picture. I saw that the Pixel class has a getGreen(); method. If I want to find the SAD of the green, would Math.abs(image1.getGreen()-image2.getGreen()); work? I was planning to have 2 nested loops running through each column and row for each image and just find the SAD of the green value.
