Using Parallel Arrays To Store Names And Job Titles Then Display Combo Depending On Input
Dec 24, 2014
I am trying to use parallel arrays to store names and job titles, then display the name/job title combo depending on which is entered. I have always struggled with arrays, so I'm sure that's where my issue is, but I am not sure how to resolve this one. I tried to use the toString() method with the jobs to see if that would allow the job title to match to one of the titles listed, and I tried to not use the toString() method with the names to see if that would allow the name entered to match to one of the names listed in the array. Both options only display the "invalid" message no matter what I enter. What would be the best choice to use the arrays to properly display the information ....
import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JEmployeeTitle2 extends JApplet implements ActionListener
{
Container con = getContentPane();

public static void main(String[] args)
{
int v1 =0, v2 = 0, v3 = 0, v4 = 0;
int n;
char response;
System.out.print("Enter number of rolls (100-1000): ");

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.

The assignment was to create 3 parallel arrays to make a student database.The first array will contain 4 digit student id's, the second a string array with student names, and the third array is student gpa's. The user is to receive a dialog box asking to enter the student id, and if the id is correct the user is to see the student name and grade. If the user input does not match any value in the student id array, the user is to receive a message stating invalid id. Here is the code I have so far.
For some reason no matter what the user enters, the information for the last array entry is displayed.
public class parallelStudent
{
public static int sequentialSearch(int[] array, int value)
{
int index; //loop control variable
int element; //element the value is found at
boolean found; //flag indicating search results

I am trying to sort a set of parallel arrays. I really believe that the code is correct, but it is not working out as expected.This is the specific code for the sort:
Java Code: for (int y = 1; y < (dataArray.length + 1); y++)
{
for (int x = 0; x < dataArray.length - 1 ; x++)
{
if ((dataArray[x][1]) <= (dataArray[x + 1][1]));
{
tempOpen = dataArray[x][1];
dataArray[x][1] = dataArray[x + 1][1];
dataArray[x + 1][1] = tempOpen;
[code]....

I'm building a text based "game" where you are communicating with this android creature called Gargoid , at a VERY primitive level . how it works is, simply the user type in a sentence which is decoded for meaning by comparing it with a built in list of words in order to figure out what the user is saying, and then reply with a a relevant response also from a list of built in words. the whole thing would look something like this,
user: what is your name
Gargoid : my name is Gargoid, nice to meet you
user: how is the weather
Gargoid: the weather is wonderful
so far I have 11 arrays which are the following
String[] for user typed in words used for comparison to find meaning ..An Array of String[] , 7 so far, to hold what I call the Gargoid dictionary for example String[] greeting={hi,hello,aloha}, words that indicates greeting int[] called frequency to determine which of the 7 arrays have the greatest "relevancy" to what is being said. and finally another String[] for responses here's the actual code, I want you guys to tell me if there's a way to reduce all this never ending number of arrays? and also is this code a good application of object oriented programming?
MainClass
public class GargoidMain {
public static void main(String[] args) {
TheKeyBoard keyboard=new TheKeyBoard();
TheTranslator translator=new TheTranslator();
TheBrain brain=new TheBrain();
translator.translate(keyboard.userSaysWhat());
brain.respond(translator.userSays());

I have to write a program that calculates the average temperature for a month using parallel arrays (it is mandatory to use a parallel array). I'm new to Java (I'm more familiar with C++) so I get confused with the use of methods. I know how to compute the averages already, I just setting up the parallel arrays. This is what I have so far:
Java Code:
import javax.swing.*;
import java.util.Scanner;
public class Temperature {
public static void main(String[] args) {
String[] day = {"Monday", "Tuesday", "Wednesday",
"Thursday", "Friday", "Saturday", "Sunday"};
int[] temp = new int [7];
[Code] .....
For now I just want to show the contents in my array before I start computing averages.

I'm not asking the code to make this program, I have trouble to understand the algorithm to make this program ...

I am having an issue with a parallel array that I created that returns array values based on an input. The code only works for the first four array locations just fine. The remaining values are not found. I thought it might be a memory allocation issue with the array size, I tried to dimension the array, however, using the Eclipse editor get errors.
import java.util.*;
import javax.swing.JOptionPane;
public class StudentIDArray {
static String[] studentNum = new String[]
{"1234", "2345", "3456", "4567", "5678", "6789", "7890", "8901", "9012", "0123"};
static String[] studentName = new String[]

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

When I add an array of action-objects (the class extends AbstractAction)
to a combo box, I do receive the action performed events, great!
But the combo box items show the long string of the action object, of course!
How to render that string in a way that only the Action.NAME appears?
I was experimenting a little, but could not make it to work:

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.

I have a college question ask me to write a class StringRevert which does the following:
-prompting user for an interger n
-creating an array of n string
-repeatedly read character string from user input and store them in the array until end of array is reached or user input -quit(quit should not saved in array)
-print the string from array in reverse order, from last enter to first enter.
-assume user always supplie correct input
This is what I've done so far but how to get it working.
import java.util.Scanner;
public class StringRevert {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("enter value of n: ");
int n1 = in.nextInt();

I'm playing with vectors for the first time... What I'm trying to do is to allow a user to input one or more integers and store them in a vector for manipulation later on in the program... Here's the portion of the program I'm working with:
Java Code:
package com.itse2317;
import java.util.*;
public class VectorTest
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
[code]...
My question is this: Is there any way to move from inputting integers to printing them, without entering a non-integer (for example, hitting enter)? I looked at the API for the Vector class, and either I'm not thinking about the problem the right way to be able to find an answer, or it's just not there.

Write a program to maintain a list of the high scores obtained in a game. The program should first ask the user how many scores they want to maintain and then repeatedly accept new scores from the user and should add the score to the list of high scores (in the appropriate position) if it is higher than any of the existing high scores. You must include the following functions:
-initialiseHighScores () which sets all high scores to zero.
-printHighScores() which prints the high scores in the format: “The high scores are 345, 300, 234”, for all exisiting high scores in the list (remember that sometimes it won’t be full).
-higherThan() which takes the high scores and a new score and returns whether the passed score is higher than any of those in the high score list.
-insertScore() which takes the current high score list and a new score and updates it by inserting the new score at the appropriate position in the list

I am writing a program that grab user input number which represent beats per minute separated by commas. It then parses the numbers and reorders them from smallest to largest and then outputs the average, medium, maximum and minimum number all in separate lines. I am having trouble getting the array to sort the input from smallest to largest. It is currently only working for 3 numbers inputted. Anything more will not reorder it.

I am new to using arrays. I need to collect user input for book title, author, and # of pages... store that in an array... and then I'm going to need to be able to sort that array. The dialog boxes come up prompting the user for 5 sets of title, author, and # of pages, but when I try to display that information, it isn't working. I am assuming this means that it's not storing the information correctly... so I want to get this corrected before I even try to sort??
