Keeping Track Of Product With Highest Price - Loop Condition
Sep 22, 2014
The Program prompts the user to enter the number of products in the product catalog. The program should then prompt the user for the name and the price of each product in the product catalog. Once all of the products have been entered, the program should output the product information (name and price) of the most expensive product in the catalog. Your solution to keep track of the product with the highest price.
import java.util.Scanner;
public class ProductTester {
private static final String price = null;
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
System.out.print("Enter the number of Products: ");
int count = console.nextInt();

Here are my conditions: You are developing a program to keep track of team standings in a league. When a game is played, the winning team (the team with the higher score) gets 2 points and the losing team gets no points. If there is a tie, both teams get 1 point. The order of the standings must be adjusted whenever the results of a game between two teams are reported. The following class records the results of one game.
public class GameResult
{
public String homeTeam() // name of home team
{ /* code not shown */ }
public String awayTeam() // name of away team
[Code] ....
The class TeamStandings stores information on the team standings. A partial declaration is shown below.
public class TeamStandings
{
TeamInfo[] standings; // maintained in decreasing order by points,
// teams with equal points can be in any order
public void recordGameResult(GameResult result)
[Code] ....
And here is the actual question:
Write the method adjust. The method adjust should increment the team points for the team found at the index position in standings by the amount given by the parameter points. In addition, the position of the team found at index in standings should be changed to maintain standings in decreasing order by points; teams for which points are equal can appear in any order.
And here is what I have so far:
private void adjust(int index, int points)
{
int Score[] = new int[standings.length]
for ( int i=0; i <= standings.length; i++)
{
Score[i] = index, points;
}
}

My program is supposed to be used to keep track of inventory for a company. The user is prompted with a menu that asks them which item they want to update and then gives them another menu that allows them to buy, sell, or change the price of the items. For this, I need to have the variable values to change (based on the input of the user), because they are initially set to specific numbers. How would I do this?
Here's the part of my code that is relevant to this question:
balance = 4000.00;
lampQuantity = 400;
lampPrice = 10;
chairQuantity = 250;
chairPrice = 20.00;
deskQuantity = 300;
deskPrice = 100.00;
System.out.println("Current Balance: $" + balance);
System.out.print("1. Lamps " + lampQuantity);
System.out.println(" at $" + lampPrice);
System.out.print("2. Chairs " + chairQuantity);
System.out.println(" at $" + chairPrice);
[Code] .....

I have a TableView and it is scrolled to have some rows visible. Lets call the top visible row T, and the bottom one B.
I now replace the items in the TableView with a whole new list of items (so new data to view), but I want to scroll back to either T or B.
It seems to me that I have to somehow keep track of the topmost visible row, or the bottom-most visible row, but I can't figure out how to do that.

So, I have this simple program that paints a string on JPanel using g2.drawString("Hello world", 40, 120). Basically, I want to be able to keep track of many strings on the JPanel at once. I'm not sure how to do this. For example, I would want to have an ArrayList of objects that keep track of these strings.
I want to be able to click-and-drag these strings so I will need to know there locations, etc.
Right now, using g2.drawString, it only draws the string. I want something like gw.draw(myStringObject).

I am trying to design a monopoly board game with a class and a main program. I can not make the method to keep track of the player's position after every roll. After every roll it prints "Previous position: 0".The player should also not go over 14th spot because the board is just 15 including 0. That is what I have (just the particular method and the part from the main program which call it).
public int getpospl1()
{
System.out.println( getplayer1name() + " Rolls "
+ "Dice 1: " + getrolld1() + "" + "Dice 2: " + getrolld2() + "" );
int spot1 = 14; //The end spot
int start = 0;
int previousPosition = start;

I'm not following how it calculated to 95 since I'm confused with this

I wanted to know if I was off to the right start. I am trying to write a program using the for loop the calculate the product of the consecutive numbers 4 through 8 but so for I am getting 3 values output and I only want 1 value at the print out.
The code I am using outputs the numbers too large. I am trying to see where I went wrong.
for ( int i = 4 ; i <= 8; i++)
{
int j = i++;
int k = j++;
int l = k++;
int m = l++;
System.out.println( + (i*j*k*l*m) );

What I am trying to do here is allow input to loop until 0 is entered for the product number. When 0 is entered, it should then dump the total for each individual product. I've tried it about a dozen different ways and have yet to be able to get the loop to function as intended. The way I have the code below, the loop will not function at all (where as before it looped, but never finished).
import java.util.Scanner;
public class Sales {
public static void main(String[] args) {
double total1=0.0;
double total2=0.0;
double total3=0.0;
double total4=0.0;
double total5=0.0;
int product;

I am trying to split a string into a String[] tokens array to declare variables for an object; however, I'm having an issue getting the string to tokenize correctly. Here's an example of the input:
a : 100 : John Smith : 20 Main St.
a : 101 : Mary Jones : 32 Brook Rd.
Here is the basic code I have now, to properly sort each line of text, etc. (without the split() method):
Java Code:
while (scanner.hasNextLine()) {
currentLine = scanner.nextLine();
lineScan = new Scanner(currentLine);
if (currentLine.startsWith("/") || currentLine.trim().isEmpty())
continue;
[Code] ....
I was able to eliminate the comments and identifiers from the text by trimming the first two characters of the string. For the split, I tried String[] tempArray = currentLine.split("s+"); however, that also took the spaces out of the addresses and names...so the results looked like this:
100
John
Smith
20
Main
St.
As you can see, it splits via space regardless, including where I replaced all the :'s with spaces. Is there any way to do this?

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 am not sure what is happening with my code, but it is giving me a negative number. I am trying to write a program that calculates the product of the odd integers between 1 and 25. I messed with the program and as soon as you enter a number over 22, the end result is a negative number.
int total = 1;
for (int i = 1; i <= 25; i += 2){
total *= i;
}
System.out.println("Product:" + total);

The question is when you send two messages from the client to the server does the server read the messages as one input or do you have to read both inputs on the server side?
Im using DataInputStream and DataOutputStream
On the client side I send two messages one for the database action to be performed and the send is the information needed to get the job done.
Example I want to search for a product in the database.
I send to the server an output message saying search product. I then send to the server which product I want to be searched.
The server then retrieves the message by in.readUTF(); switch statement determines what database action should be performed. Within that case I call another in.readUTF() to pass the information to the database on what product to search for.
Would this work or would the server read both messages from the client as one input stream?

Below is current process :
We have an application running successfully where we fetch the weight of product currently on Production Line using Java.
All the products on line belong to same order and are of same type.
User at beginning enter the type of product and starts the production line.
Proposed new process: Now client want that multiple type of product can belong to same production order. i.e. on a production line different type of products can come one after other. So we should now fetch the type of product also.
The Question : what are different possibilities in which we can find the type of product. Can java fetch color of a box ? If we use scanner on line that scans the product and sends the color information to Java.
Above is just a possibility. Can there be any other parameters that Java can use to differentiate in type of product ?
Currently we are clueless. What ever are the possibilities in Java we can propose the same to client. Even if that requires additional hardware.

For an assignment
-I am too write a program that checks if 3 numbers (scannerinputted) are three sides of a triangle if not just ignore it.
-If they are the 3 sides to a triangle tell what kinda triangle it is Right/scalene/equilateral etc.
-ignore the 3 numbers if they are <=0
if(side1+side2>side3 && side1+side3>side2 && side2+side3>side1)
System.out.println("This is a Triangle.");
else
System.out.println("Not a Triangle.");
How can I make the program stop immediately if the else statement is checked. I have more "if statements afterward.
so it would say.
"This not a triangle"
"This is scalene or isosceles"
how can I get this output.
"This is not a triangle" and stop there.

I m trying to simplify an if condition as much as possible and i m curious if it can be made more short then i managed to .The problem is simple , a integer number with 3 digits is generated and the user is asked to input another 3 digits integer number ... One of the conditions that need to be verified is if all the digits in each number match but not exactly ( aka 123 and 132 ) .Using only an if statement to verify this what is the most short condition that can be checked to identify when the digits in a 3 digits number match the digits of another 3 digits integer number (not interested if they match exactly) .
The simplest condition i managed to find is :
else if (guessDigit1 + guessDigit2 + guessDigit3
== lotteryDigit1 + lotteryDigit2 + lotteryDigit3
&& (guessDigit1 == lotteryDigit1 || guessDigit1
== lotteryDigit2 || guessDigit1 == lotteryDigit3)
&& (guessDigit2 == lotteryDigit1 || guessDigit2
== lotteryDigit2 || guessDigit2 == lotteryDigit3)) {
System.out.println("Match all digits: you win $3,000");}
Is there a better(shorter ) condition that can be used ?

My problem is that in my program, I have the user input data for one of three product objects, however when I read the data for all three objects, the same data is stored in all of them.
Anyway this is the method from the Interface class:
private void readInput() // the only method in the program that accepts product data from the user {
Store matesStore = new Store();
String name;
int demandRate, productChoice;
double setupCost, unitCost, inventoryCost, sellingPrice;
Scanner console = new Scanner(System.in);
[Code] ....
And here is the method from the Store class:
public static void addData(int option, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice)
//sets the product data for a particular product {
if (option==1) setData(product1, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else if (option==2) setData(product2, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else /*(option==3)*/ setData(product3, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
[Code] ....
The problem I had was with static variables and methods.

public class InputFileData {
/**
* @param inputFile a file giving the data for an electronic
* equipment supplier’s product range
* @return an array of product details
* @throws IOException
*/
public static Product [] readProductDataFile(File inputFile)
throws IOException{
// YOUR CODE HERE
}
This code is meant to be used to read a text file and store the data in an array of type Product[]. I know how to read in a text file and have it sort it into an array, but I've never seen code laid out in this fashion before (specifically "public static Product[]", and I'm unsure how to work with "(File inputfile)". I've looked all over the place but can't find any examples of anything like this.
Also, the code given cannot be changed, as it's that code I have to work with.
I still don't understand how to use it as a whole. For example, do I read the file in the main and have this method read that in and output to the Product class? Do I read the file in this method? I can't work out how to make this work when I have to use this method.
