Arrays Program Issues - Essay Example

It also uses loops to find out if 4 exists in the array and ejects the loop if it exists at a given index.

BostonMarathon.java using NetBeans IDE:
public class BostonMarathon {
/**
* @param args the command line arguments
*/ public static void main(String[] args) {
// TODO code application logic here
int startMileage=2;
int endMileage=26;
//8 weeks excluding the first and last week
int interval=(endMileage-startMileage)/8;
int weeklyMiles[]=new int[10];
for(int x=0;x<=9;x++){
weeklyMiles[x]=startMileage;
startMileage+=interval;
//Array element at index 2
System.out.println("Value at index 2:"+weeklyMiles[2]);
//Length of array
System.out.println("Lenght of array:"+weeklyMiles.length);
//Summation of total mileage
//Initialize total mileage to 0
int totalMileage=0;
for(int x=0;x<weeklyMiles.length;x++){
totalMileage+=weeklyMiles[x].

System.out.println("Total Distance Travelled:"+totalMileage);
float average;// declare variable to hold average
System.out.println("Average Mileage:"+(float)totalMileage/10);
//Search if 4 exists in the array
for(int y=0;y<weeklyMiles.length;y++){
if(weeklyMiles[y]==4){
System.out.println("4 is present at index:"+y);
break.

Output:
Value at index 2:8
Length of array:10
Total Distance Travelled:155
Average Mileage:15.5.
