Thread: Counting a total and printing value from 2 arrays

Hi Guys!

This is my first post and i am a complete newbie to Java...

I am trying to total and print the number of apples in each basket. But when i print it prints each transaction at each point in the array, causing a double up in my print information. Did that make sense? Please see below.

this is my code so far...

int size = 10;
int arrayOneValue;
int arrayTwoValue;
int count;
int maxBasketNumber;
int appleCount;

maxBasketNumber = 0;
for (arrayOneValue=0; arrayOneValue < size; arrayOneValue = arrayOneValue +1)
{
if(BasketNumber[arrayOneValue] > maxBasketNumber)
maxBasketNumber = BasketNumber[arrayOneValue];
}


appleCount = 0;
for (arrayOneValue=0; arrayOneValue < size; arrayOneValue = arrayOneValue +1)
{
count = 0;
for(arrayTwoValue = 0; arrayTwoValue < size; arrayTwoValue++)
{
if(BasketNumber[arrayOneValue] == BasketNumber[arrayTwoValue])
count++;
}
System.out.println("BasketNumber: " + BasketNumber[arrayOneValue] + " Total of apples: " + count);
System.out.println("");
appleCount++;
}
System.out.println("");


This is the output:


BasketNumber: 1 Total of apples: 3 // I would like to print each BasketNumber only once with its value not repeat the same info

BasketNumber: 1 Total of apples: 3

BasketNumber: 3 Total of apples: 3

BasketNumber: 0 Total of apples: 2

BasketNumber: 3 Total of apples: 3

BasketNumber: 2 Total of apples: 1

BasketNumber: 0 Total of apples: 2

BasketNumber: 4 Total of apples: 1

BasketNumber: 1 Total of apples: 3

BasketNumber: 3 Total of apples: 3


Any help would be greatly appreciated!

2 small things. First of all, try using the .code=java] ./code] tags (replace the . with a [) so it's easier to read. Also why do you do

arrayOneValue = arrayOneValue +1

instead of just arrayOneValue++? makes life so much easier, and you are doing it in your other for loop as well.

Also could you give us a runnable version? makes it easier to look at the problem. For example what is BasketNumber? And how many elements can it store (the size)?

Ok i will make those changes

import java.util.*;

public class basket
{
public static long number=1234567;

public static int basketNumber[];
public static double apples[];


{
basketNumber=new int[size];
apples=new double[size];

Random rand=new Random(number);
for (int i=0;i<size;i++)
{
basketNumber[i]=rand.nextInt(size/2);
apples[i]=rand.nextInt(10000)/100.0;


}
}



public static void main(String args[])
{
int size=10;

initialiseData(size);


int arrayOneValue;
int arrayTwoValue;
int count;
int maxbasketNumber;
int appleCount;


maxbasketNumber = 0;
for (arrayOneValue=0; arrayOneValue < size; arrayOneValue = arrayOneValue ++)
{
if(basketNumber[arrayOneValue] > maxbasketNumber)
maxbasketNumber = basketNumber[arrayOneValue];
}


appleCount = 0;
for (arrayOneValue=0; arrayOneValue < size; arrayOneValue = arrayOneValue ++)
{
count = 0;
for(arrayTwoValue = 0; arrayTwoValue < size; arrayTwoValue++)
{
if(basketNumber[arrayOneValue] == basketNumber[arrayTwoValue])
count++;
}
System.out.println("Basket Number:: " + basketNumber[arrayOneValue] + " Total of apples: " + count);
System.out.println("");
appleCount++;
}
System.out.println("");



This what output should look like...
Basket Number: 1, Apples: 3
Basket Number: 3, Apples: 3
Basket Number: 0, Apples: 2
Basket Number: 2, Apples: 1
Basket Number: 4, Apples: 1


Thanks for your help
