Thread: Help with my program

Hi All,

I am trying to write a program that basically determines the max amount of units sold and displays it in a dialog box. Also, the program will display the winning sales associate out of 10. I have wrote the program successfully so far and I can see the maximum number of units sold displayed in the dialog box, but I cannot seem to link the winning sales person.

Here is the code I have typed so far.

//Program to find maximum of three number


import javax.swing.JOptionPane;
import java.util.Scanner;
public class Sales
{
public static void main (String[] args)
{

//Declare variables
int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10;
int large;
int winner;

//Create scanner object to receive user input
Scanner input = new Scanner(System.in);

//Prompt the user for input numbers
System.out.print("Enter units sold by sales person # 1 : ");
num1 = input.nextInt();

System.out.print("Enter units sold by sales person # 2 : ");
num2 = input.nextInt();

System.out.print("Enter units sold by sales person # 3 : ");
num3 = input.nextInt();

System.out.print("Enter units sold by sales person # 4 : ");
num4 = input.nextInt();

System.out.print("Enter units sold by sales person # 5 : ");
num5 = input.nextInt();

System.out.print("Enter units sold by sales person # 6 : ");
num6 = input.nextInt();

System.out.print("Enter units sold by sales person # 7 : ");
num7 = input.nextInt();

System.out.print("Enter units sold by sales person # 8 : ");
num8 = input.nextInt();

System.out.print("Enter units sold by sales person # 9 : ");
num9 = input.nextInt();

System.out.print("Enter units sold by sales person # 10 : ");
num10 = input.nextInt();



//Initialize large number
large = num1;
winner = num1;

//Compare other numbers with large and reassign

if (num2 > large)
large = num2; //assign num2 to large

if (num2 > winner)
winner = num2;

if (num3 > large)
large = num3; //assign num3 to large

if (num3 > winner)
winner = num3;

if (num4 > large)
large = num4; //assign num4 to large

if (num4 > winner)
winner = num4;

if (num5 > large)
large = num5; //assign num5 to large

if (num5 > winner)
winner = num5;

if (num6 > large)
large = num6; //assign num6 to large

if (num6 > winner)
winner = num6;

if (num7 > large)
large = num7; //assign num7 to large

if (num7 > winner)
winner = num7;

if (num8 > large)
large = num8; //assign num8 to large

if (num8 > winner)
winner = num8;

if (num9 > large)
large = num9; //assign num9 to large

if (num9 > winner)
winner = num9;

if (num10 > large)
large = num10; //assign num10 to large

if (num10 > winner)
winner = num10;


//Extra line

System.out.println();

//Print the largest number

//System.out.printf("Maximum units sold: %d \n", large);


String message = "";

message = message + String.format("Maximum units sold: %d \n", large);

message = message + String.format("Winning sales person: %d", winner);

JOptionPane.showMessageDialog (null, message);

}//End main method

}//End class

What do you want to show as the winner. Right now you are copying the same value of highest sales to the winner as well, and that is working fine.

Well when you're assigning winner, you're assigning the amount the person sold, rather than which person sold it.

Hi,

as per my understanding of what you are trying to do, does sample output below fit your need?

eg :

Enter units sold by sales person # 1 : 5
Enter units sold by sales person # 2 : 1

Maximum units sold: 5
Winning sales person: 1

maybe you could use a POJO? (Plain Old Java Object)

class salesVO{
 
	int sales;
	int salePerson;
	public int getSales() {
		return sales;
	}
	public void setSales(int sales) {
		this.sales = sales;
	}
	public int getSalePerson() {
		return salePerson;
	}
	public void setSalePerson(int salePerson) {
		this.salePerson = salePerson;
	}
 
 
 
}

basically you make an array of salesVO and use it to relate the sales person to the number of greatest sales

eg :

		//Prompt the user for input numbers
 
		salesVO[] sVO = new salesVO[10]; 
 
		// maybe instead of repeating this block of code via hard coding
		// use for loop?
		System.out.print("Enter units sold by sales person # 1 : ");
		num1 = input.nextInt();
		sVO[1].setSales(input.nextInt());
		sVO[1].setSalePerson(1);

other options that i can think of are maps, and 2d Arrays.

You would want to put the sale person starting at position 0 instead of 1

a yes sorry, my bad thank you for pointing it out
carelessness will definitely be the end of me

So it's solved then?

Hello,

Yes you are correct. But I have not learned about this in my class so I cannot use it. Are there any other basic java concepts that can achieve this? This is for a HW assignment I am trying to complete.

--- Update ---

How would I assign which person sold it?

Hi

how about arrays?

eg :

		int[][] x= new int[10][2];
 
		x[0][0]  = 100; // sales
		x[0][1] = 1; //agent	
 
                x[1][0] = 20;
                x[1][1] = 2;

...till 10 inputs are acquired.

actually, how far did your class covered? just to have an idea on what your looking for

regards

We have not done arrays yet. So far I have changed the code and maybe this will help.

//Program to find maximum of three number


import javax.swing.JOptionPane;
import java.util.Scanner;
public class Sales
{
public static void main (String[] args)
{

//Declare variables
int large = 0;
int num;
int counter = 0;
int winner = 0;

//Create scanner object to receive user input
Scanner input = new Scanner(System.in);

while (counter <10)
{

System.out.print("Enter units sold by sales person # %d " +counter);
num = input.nextInt();

if (num > large)
{

large = num;
winner = counter;

}

counter++;

}


String message = "";

message = message + String.format("Maximum units sold: %d \n", large);

message = message + String.format("Winning sales person: %d", counter);

JOptionPane.showMessageDialog (null, message);

}//End main method

}//End class

you have actually solved it already

though

message = message + String.format("Winning sales person: %d", counter);

this line will always display the max value of 'counter'.

try displaying 'winner'
