Question
Write the word or phrase that best completes each statement or answer the question The following declaration is used throughout this example: double [] sales = new doublet [10]; int index; double largestSale, sum. average; Write the code to do the following: Initialize every component of the array to the value 0 Read data from the keyboard and store it in the array. You will be filling the whole array. Print all of the items in the array in reverse order. Find the sum and the average of the elements in the array. Determine the smallest and largest element of the array.Explanation / Answer
a)
import java.util.Scanner;
public class Cray {
public static void main(String[] args){
final int SALESPEOPLE = 5;
int[] sales = new int[SALESPEOPLE];
int sum, maxperson, minperson;
int max = sales[0];
int min = sales[0];
Scanner scan = new Scanner(System.in);
//Fill the 5 element array of sales with the user's input
for (int i=0; i<sales.length; i++)
{
System.out.print("Enter sales for salesperson " + i + ": ");
sales[i] = scan.nextInt();
//Calculate the max and min sales
//How do I return the salesperson i with the the max and min sales?
if(sales[i] > max){
max= sales[i];
maxindex = i;
}
if(sales[i] < min){
min = sales [i];
maxindex = i;
}
}
System.out.println(" Salesperson Sales");
System.out.println("--------------------");
sum = 0;
for (int i=0; i<sales.length; i++)
{
System.out.println(" " + i + " " + sales[i]);
sum += sales[i];
}
System.out.println(" Total sales: " + sum);
System.out.println("Average sales: " + sum/5);
//WHere I want to print the max salesperson.
System.out.println("Salesperson" + );
}
}

}
j = i - 1; // now j will point to the last element

while(i<j)
{

}

int a[] = new int[n];
System.out.println("Enter all the elements:");
for(int i = 0; i < n ; i++)
{

}
System.out.println("Sum:"+sum);

System.out.println("Average:"+average);
}
}
e)
class MinMaxExample {
public static void main(String args[]){
int array[] = new int[]{10, 11, 88, 2, 12, 120};
// Calling getMax() method for getting max value
int max = getMax(array);
System.out.println("Maximum Value is: "+max);
// Calling getMin() method for getting min value
int min = getMin(array);
System.out.println("Minimum Value is: "+min);
}
// Method for getting the maximum value
public static int getMax(int[] inputArray){
int maxValue = inputArray[0];
for(int i=1;i < inputArray.length;i++){
if(inputArray[i] > maxValue){
maxValue = inputArray[i];
}
}
return maxValue;
}
// Method for getting the minimum value
public static int getMin(int[] inputArray){
int minValue = inputArray[0];
for(int i=1;i<inputArray.length;i++){
if(inputArray[i] < minValue){
minValue = inputArray[i];
}
}
return minValue;
}
