Calculate SUM And AVERAGE Of ODD Number Digits Between 25 And 75
Jun 19, 2014
You are to write a parallel program that will receive a large array of unsorted integers containing digits from 0 to 99. The program will have to calculate the SUM and AVERAGE of ODD number digits between 25 and 75 (inclusive).
The user may specify the size or the array and the total processor that the machine has. The size of the array must be divisible by number of processor. Based on the given size, the computer will generate random integer numbers automatically to populate the array.
The program should display the status of the calculation for each processor. The result should be displayed after all calculations are completed.Error messages should be displayed appropriately
a) Write a sequential (non-parallel) program that will accomplish above task.
b) Write a concurrent (parallel) program that will produce the result of the above task.

Goal is to: Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
First I don't know where I made mistakes here, and the only error it finds right now is that str2 was not initialized and I cannot figure out where/when to initialize it.
import javax.swing.JOptionPane; public class DigitsAndSum { public static void main (String[] args) { String str1; String str2; int int1 = 0; int int2 = 0;
I am having a problem with my program. I can't get my program to calculate properly. Everything compiles and run but its just giving me a wrong answer. I am suposse to get 115.50 but instead I am getting .30...
order.java public class Order { double salesTaxRate; //initializing a variable for the sales tax rate. double subTotal; //initializing a varliable for the sub total. double shippingCost; //initializing a variable for shipping cost. double salesTax; //initializing a variable for sales tax. double totalCost; // initializing a variable for totale cost.
Make a program which takes input from the user (6-digit number) and check how many times each digit gets repeated in the number. Java GUI was used (Netbeans 6.5.1).This is my code. I took the input via a JTextField named tf and displayed the output on JTextArea ta.
- arrays not used as we haven't studied them yet
int num= Integer.parseInt(tf.getText()); int no=num; if(num<100000) ta.setText("Invalid Input. Please Enter 6 digit number"); int n1= num%10; num=num/10; //stores last digit
[code]....
How do I omit the last 5 lines? This problem occurs whenever I input a digit with any recurring digit.What changes/additions should I make?
I wasn't supposed to use the % in front of f.I have to make a program to calculate the average temperature and annual precipitation in Jacksonville. I get this error on line 49:
java.util.IllegalFormatPrecisionException; null (in java.util.Formatter$FormatSpecifier)
I don't get any errors during compilation.Here is my code (I'm not using the system selection yet):
import java.util.Scanner; public class AnnualClimate1 { public static void main(String[] args) { double[] temperaturesInJacksonville = {53.1, 55.8, 61.6, 66.6, 73.4, 79.1, 81.6, 80.8, 77.8, 69.4, 61.7, 55.0};
Write a program to simulate this airport's operation. You might assume a simulated clock that advances in one-minute intervals. For each minute, generate two random numbers: If the first in less than LandingTime /60, a "landing arrival" has occurred and is added to the landing queue, and if the second is less than TakeOffTime /60, a "takeoff arrival" has occurred and is added to the takeoff queue.
Next, check whether the runway is free. If it is, first check whether the landing queue is nonempty, and if so, allow the first plane to land; otherwise, consider the takeoff queue. Have the program calculate the average queue length and the average time that an airplane spends in a queue.
I have most of the code done as you can see below:
Right now, I am stuck on the first calculation which is trying to figure out the average size of the landing queue. For some reason, as you can see at the bottom of my demo program, the average always comes out to be 0.0 and I'm not sure what's wrong.
Secondly, how to calculate the average time a plane stays inside a queue for.
Given a Numbers instance, whose fields are arrays of all the built-in Java numeric types (int, long, float, double, big-decimal, etc), write a method to sort all the numbers into a master list, and then print out the numbers where the number of digits past the decimal point is equal to the index of the number in the master list.
Is there a function in Java that will give me just the numbers after the decimal? I tried Decimalformat but couldn't get it to work. Here is what I have so far; however, I think I might be on the wrong track.
public class Numbers { public static void main(String[] args) { Byte bNum = new Byte((byte) -50); Integer iNum = new Integer(168); Long lNum = new Long(100000L); Short sNum = new Short((short) 10000); Float fNum = new Float(12.19f); Double dNum = new Double(23.123); BigDecimal bd = new BigDecimal("3.14159265358979323846");
I have returned with yet another problem but I think this one might be a bit easier to fix.
So the whole MO of this program is to take user input, and display the sum of the digits of the number they entered. I am supposed to do this by utilizing methods. So far this is what I have and when I compile it tells me that it "cannot find symbol", which I don't understand as I define what "m" is in the for loop. The other error is that it says:
"Exercise6_2.java:22: error: incompatible types: possible lossy conversion from long to int return result; ^
I don't understand why it's giving me this error nor do I understand why result seems to inherently be an int. (Also the public static int sumDigits(long n) method was given to me by the book so that is what I am supposed to use).
import java.util.Scanner; public class Exercise6_2 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter a integer"); long n = input.nextLong();
In a forest, there are some bamboo trees .The length of each tree get doubled during winter and increases by one unit in summer , write a Java program to calculate the total length of n number of bamboo trees in M number of seasons. The season always starts with winter.
import java.util.Scanner; public class Tree { public static void main(String args[]) { int length; int season;
Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
Now I have a code for spacing out the integers, and I have a separate code for adding the digits. But I am not sure how to merge them together. Both of them work independently
Spacing code: import java.util.*; public class SumoftheIntegers { static Scanner console=new Scanner(System.in); public static void main(String []args) { int num1, test, rem; int counter = 0;
[Code]...
Now the sum of the integers code:
import java.util.Scanner; public class sum { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in); // Enter amount System.out.print("Enter an integer: "); int integer = input.nextInt();
Find the numbers which is closest to the average sum for a given array of N (1<=N<=50) of natural numbers. If there are two numbers who meet the requirement, return the smaller of the two.
For example for the array of: 1,2,3,4,5,6 the average sum is 3.5, so both 3 and 4 are the closest to that, but the program has to return 3, because it's smaller than 4.
The array can also contain duplicates. First we type the number of elements in the array, then in each line we add the numbers. Name of the class: Array
**Note**: Create a data structure array and use it.
And this is what they have given to me, I just need to type the code:
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class Array<E> { public static int closestNumber( ) {
I am writing a program using a given test drive... I am supposed to write two classes according to the test drive. The calculated correct answer should be 115.50 but i keep getting 115.52 instead and i just can't figure out what i'm doing wrong.
Here is the test drive code:
import java.text.NumberFormat; public class FinalTester { public static void main(String[] args) { double avgPurchase; Order[] lastYear = new Order[4];
I am to design a program in java that will allow a user to Input a list of your family members along with their age and state where they reside. Determine and print the average age of your family and print the names of anyone who live in Texas. I have tried but my results are wrong.
My objective is to execute quick sort ( i was told to convert the pseudocode from the Cormen book) using arrays of increasing sizes and find the average number of comparisons for each of those sizes over 100 iterations. This is a school project and the numbers I am getting are far larger than those of my friends, so I am clearly doing something wrong. I believe it must be in the way that I am collecting and averaging my number of comparisons. I will first give the method in which most of that calculating is done, then I will include the whole program.
public static void tests(int arraySize) { long numComparisons = 0; long averageComparisons = 0; long[] numComparisonsArray = new long[100]; for(int i = 0; i<100; i++) { int[] array= genRandomArray(arraySize);
code a 10 * 10 matrix, with random numbers from 1 to 100,
i) Find the most repeated number. ii) Use the Binary Sort, to sort the matrix in ascending order. iii) Find the Column, with the highest average number.
Write a recursive method that calculates the Nth number in the Fibonacci sequence. The first and second numbers in the sequence (the base cases) are both 1. After that, each subsequent number is the sum of the previous two. Stated a bit more formally:
fib(n)={1fib(n−1)+fib(n−2)n<2otherwise
For example, here is the first few numbers in the sequence:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
Your fib method should be part of a class named Fibonacci. In addition to the fib method, the Fibonacci class should have a main method that calls fib(9). If the result doesn't equal 34, you should print an error message. Otherwise, it should print out a message saying that it was successful.
After writing your Fibonacci class, answer the following question: How many times is the fibonacci method called when calculating the 5th number in the sequence?
lines 7, 8, &12 "primes" are underline in red (prime cannot be resolved) is what pops up when i hover over the x's.
i don't get why that is.
package assignment7; public class Exercise3 { public static void main(String[] args) { Prime.setSize(1000); for (int p = Primes.next(); p < 30; p = Primes.next())
Lines 7, 8, &12 "primes" are underline in red (prime cannot be resolved) is what pops up when i hover over the x's.
I don't get why that is.
Java Code :
public class Exercise3 { public static void main(String[] args) { Prime.setSize(1000); for (int p = Primes.next(); p < 30; p = Primes.next()) { int n = (int)Math.round(Math.pow(2,p)) - 1; System.out.printf("%d 2^%d-1%d", p, p, n); if (Primes.isPrime(n))
I have to create a program that calculates the nth Fibonacci number and returns that to the user. Fibonacci said his number sequence would describe the ideal breeding patterns of immortal rabbits. So, you are going to make this vision a reality.
First, take in a numeric value from the user and calculate that value in the fibonacci series. Next, find an image of a rabbit and display the image on a GUI (put the image as an icon on a label!) the number of times returned by the algorithm (Put all the aforementioned labels on one panel with FlowLayout!).
You need to remove the old images from the Panel. Probably the easiest way to do this is to create a whole new panel and remove the old one (hint: the remove method of JPanel should come in handy)
You could use an array of JLabels You will need to create a new JLabel and add each member of the array to the panel I should be able to scroll to see any images that are off screen
I am having difficultly on to making the array list for JLabel, and getting the Fibonacci sequence to show the pictures of rabbits. Below is my current code.
import java.awt.FlowLayout; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Rabbit extends JFrame
This is supposed to get a certain number of items, and then calculate how much every item costs. It adds up the sum of those prices and checks if it is over 150$, if it is, it returns true, if it's not, it returns false.
import java.util.*; class Cust { public static boolean DelPay (int a) { Scanner reader=new Scanner (System.in); int b,s=0; for (int i=1;i<=a;i++) { b=reader.nextInt(); s=s+b; } if (s>150) return true; return false; } }
