    copied!<p>Thoroughly confused on how to do this. What I want to do is to place the city with the lowest min, or max in the output. My understanding is you cannot throw a string in with another datatype in a method. How in the world can I match the name with the lowest temperature?<br><br> Lets say I want 3 cities: <br> I want to make the array 3 then:<br> Then I will add in the following cities, (Alanta, New York, Richmond)<br> The cities temperatures are (42.2, 98.8, -12.4)<br><br></p> <p>Min is -12.4<br> Max is 98.8<br> That I have, how do I link Richmond's String that is stored in array[2] to temperature's double that is stored in array[2]? Any help is much appreciated. </p> <pre><code>import javax.swing.JOptionPane; import java.util.Scanner; import java.lang.Math; public class Ex9 { public static void main(String[] args) { String message =""; double min = 0, max = 0, avg = 0; int counter = 1; int numberOfCities = Integer.parseInt(JOptionPane.showInputDialog(null, "How many cities would you like to enter?")); String[] nameOfCities = new String[numberOfCities]; double[] temperatureOfCities = new double[numberOfCities]; for (int i = 0; i &lt; nameOfCities.length; i++) { nameOfCities[i] = JOptionPane.showInputDialog(null, "Please enter the name of city " +counter+" :"); temperatureOfCities[i] = Double.parseDouble(JOptionPane.showInputDialog(null, "Please enter the current temperature of the city " + counter +" :")); message += "City name " + nameOfCities[i] + ".\n" + "Temperature of city " + temperatureOfCities[i] + " is degrees\n"; counter++; }//end numberOfCities loop if( JOptionPane.showMessageDialog(null, message + "\nThe average temperature is " +findAvg(temperatureOfCities)+ "\n[Name of city] has the lowest temperature, which is " + findMin(temperatureOfCities) + "\n[Name of city] has the highest temperature, which is " + findMax(temperatureOfCities)); }//end main public static double findAvg(double[] temperatureOfCities) { double sum =0; for(int i=0;i&lt;temperatureOfCities.length;i++) { sum += temperatureOfCities[i]; } sum = sum/temperatureOfCities.length; return sum; }//end findAvg public static double findMin(double[] temperatureOfCities) { double min=0; for(int i =0; i &lt;temperatureOfCities.length;i++) { if (temperatureOfCities[i] &lt;= temperatureOfCities[0]) { min = temperatureOfCities[i]; } }//end for loop return min; }//end findMin public static double findMax(double[] temperatureOfCities) { double max=0; for(int i =0; i &lt;temperatureOfCities.length;i++) { if (temperatureOfCities[i] &gt;= temperatureOfCities[0]) { max = temperatureOfCities[i]; } }//end for loop return max; }//end findMax }//end program </code></pre>
