## Beginner: need help

I am a beginner in Java.
I wrote this code to get temperature of the days of the week, get the coolest,
hotest and average. Everything looks fine, but when I run it I get wrong
values for the hottest and coolest day.
Can anybody tell me what is wrong?

import javax.swing.*;
import java.text.DecimalFormat;

public class Lab2Ex1
{
double daysOfWeek[] = new double[7];
String nameOfDays[] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday",
"Friday", "Saturday"};

public Lab2Ex1 (double inSun, double inMon, double inTues, double inWed,
double inThur, double inFri, double inSat)
{
daysOfWeek[0] = inSun;
daysOfWeek[1] = inMon;
daysOfWeek[2] = inTues;
daysOfWeek[3] = inWed;
daysOfWeek[4] = inThur;
daysOfWeek[5] = inFri;
daysOfWeek[6] = inSat;
}
public double getAvgTemp()
{
return (daysOfWeek[0] + daysOfWeek[1] + daysOfWeek[2] + daysOfWeek[3] + daysOfWeek[4]
+ daysOfWeek[5] + daysOfWeek[6]) /7;
}
public String getHotestDay()
{
double min, max;
min = max = daysOfWeek[0];
String day;
day = "";

for (int i = 0; i < daysOfWeek.length; i++)
{
if(min > daysOfWeek[i]) {day = nameOfDays[i]; min = daysOfWeek[i];}
}
return day;
}
public String getCoolestDay()
{
double max = 0;
String day = "";
for (int i = 0; i < daysOfWeek.length; i++)
{
if(max < daysOfWeek[i]) {day = nameOfDays[i]; max = daysOfWeek[i];}
}
return day;
}
public String toString()
{
DecimalFormat df = new DecimalFormat("##.##");
return "Mon Tue Wen Thur Fri Sat Sun\n" + daysOfWeek[0] + " \t" + daysOfWeek[1]
+ " \t" + daysOfWeek[2] + " \t" + daysOfWeek[3] + " \t" + daysOfWeek[4] +
" \t" + daysOfWeek[5] + " \t" + daysOfWeek[6] + "\n\nAverage Temperature
= " + df.format(getAvgTemp()) + "\n\n" + "Hottest day = " + getHotestDay()
+ "\n\n" + "Coolest day = " + getCoolestDay() + "\n";
}
public static void main(String args[])
{
Lab2Ex1 temp = new Lab2Ex1 (12.5, 16.3, 25.5, 30.2, 19.5, 29.5, 10.5);

JOptionPane.showMessageDialog(null, temp.toString());
System.exit(0);
}
