Explanation:
Here is the code for you:
import java.io.*;
import java.util.*;
class GirlScoutCookies
{
public static void main(String[] args)
{
int [] BoxesCategory = new int[5];
Scanner sc = new Scanner(System.in);
System.out.print("Total number of girls in the troop: ");
int numOfGirlScouts = sc.nextInt();
for(int i = 0; i < numOfGirlScouts; i++)
{
System.out.print("Boxes of cookies for girl #"+(i+1)+": ");
int boxes = sc.nextInt();
if(boxes >= 0 && boxes <= 10)
BoxesCategory[0]++;
else if(boxes >= 11 && boxes <= 20)
BoxesCategory[1]++;
else if(boxes >= 21 && boxes <= 30)
BoxesCategory[2]++;
else if(boxes >= 31 && boxes <= 40)
BoxesCategory[3]++;
else if(boxes > 40)
BoxesCategory[4]++;
}
System.out.println("TOTAL BOXES\tNUMBER OF GIRL SCOUTS");
System.out.println(" 0 to 10\t"+BoxesCategory[0]);
System.out.println("11 to 20\t"+BoxesCategory[1]);
System.out.println("21 to 30\t"+BoxesCategory[2]);
System.out.println("31 to 40\t"+BoxesCategory[3]);
System.out.println("41 or more\t"+BoxesCategory[4]);
}
}
And the sample output is:
