Hi,
I suggest you first construct an algorithm to solve the problem and post the
results of your efforts. The worst thing you can do is sit down and start
hacking away at a solution without thinking clearly about the task at hand.
A well written algorithm can be mapped to any programming language
with the minimum of effort (the amount of effort expended here depends on your
proficiency with the language).

OK heres the code for the total, This works grand,

//creator: joe90kane

import javax.swing.JOptionPane;

public class Q3 {


public static void main(String[] args) {


String item,NUM;
int i;
int itemint;
int total;
int totalint;

totalint = 0;

item = JOptionPane.showInputDialog(
"Enter number of Items ");

itemint = Integer.parseInt( item );

for(i = 0; i < itemint; i++){

NUM = JOptionPane.showInputDialog(
"Enter Cost of item:" );

total = Integer.parseInt( NUM );

totalint = totalint + total;

}

JOptionPane.showMessageDialog( null,
"Total Cost " + totalint, "Results",
JOptionPane.PLAIN_MESSAGE );

System.exit( 0 );
}

}


getting the number of items & lowest costing item is giving me the problem.

Thanks joe.......

Initialise total as 0 then make a variable called let's say 'smallest'; int smallest;(initiliase it with the first value from when i is 0) then make a temp variable to place the current item value into;-> int temp;

temp = Integer.parseInt( NUM );

is what it will be now. Then just compare temp (present item value) with smallest if its less then place it into smallest and add it if not thenjust add it.

String item,NUM;
int itemint;
int totalint = 0;
int smallest;
int temp;

item = JOptionPane.showInputDialog("Enter number of Items ");
itemint = Integer.parseInt( item );

NUM = JOptionPane.showInputDialog("Enter Cost of item:" );
smallest = Integer.parseInt( NUM );
totalint = totalint + smallest;

for(int i = 1; i < itemint; i++){

NUM = JOptionPane.showInputDialog("Enter Cost of item:" );
temp = Integer.parseInt( NUM );
if(temp < smallest) smallest = temp;

totalint = totalint + temp;

}

JOptionPane.showMessageDialog( null, "Total Cost: " + totalint + " Smallest " + smallest ,"Results ", JOptionPane.PLAIN_MESSAGE );
System.exit( 0 );
}

}


That should do it tidy it up, it's a bit messy.

Thanks for that, I see where I was going wrong

Thanks joe........
