Calculate the total, the average spending for the week. Print the results of total and average spending. Count the number of days that the spending is less than the average. Print it out. Print out the highest spending day. Sample output: Enter spending on day 1:12.0 Enter spending on day 2: 65.0 Enter spending on day 3: 8.0 Enter spending on day 4: 5.0 Enter spending on day 5:15.0 Enter spending on day 6: 80.0 Enter spending on day 7: 20.0 Total spending: $205 Average: $29.29/day #of days below average spending: 5 Highest spending day: Saturday

public class SpendingLog {
  
    public static void main(String argv[])
    {
      
        int i,max=0;//varible declarations
        String week[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};
        double spendings[]=new double[7],total=0,average=0;
      
      
        Scanner sc = new Scanner(System.in);
        i=1;
        //taking user input..
        while(i<=7)
        {
            System.out.print("Enter speneding on day"+i+" :");//prompting input
            spendings[i-1]=sc.nextDouble();//reading input...
            if(spendings[max]<spendings[i-1])max=i-1;//updating max spendings
            total =total+spendings[i-1];//calculating total spendings
            i++;
          
        }
        average =total/7;//calculating average spendings
      
      
      
        int count=0;//variable to count number of days below spending average
        i=0;
        while(i<7)
        {
            if(spendings[i]<average)
                count++;
            i++;
        }
  
        //printing output...
        System.out.println("Total spending:"+total);
         System.out.println("Average spending:"+Math.round(average*100.0)/100.0+"/day");
          System.out.println("#of days below average spending:"+count);
           System.out.println("Highest spending day:"+week[max]);
      
    }
  
}

output:-

run:
Enter speneding on day1 :12
Enter speneding on day2 :65
Enter speneding on day3 :8
Enter speneding on day4 :5
Enter speneding on day5 :15
Enter speneding on day6 :80
Enter speneding on day7 :20
Total spending:205.0
Average spending:29.29/day
#of days below average spending:5
Highest spending day:Saturday
