I have an assignment for my cps class in which we have to create a program that will import a file from a server that has a bunch of numbers in it. The program is suppose to take those numbers, sort them, give the minimum and maximum value, average, median, and print the data. But when I compile it, it states that "java:12: error: unreported exception FileNotFoundException; must be caught or declared to be thrown". What does it mean???
import java.util.*;
import java.io.*;
public class sorting
public static void main(String[]args)
{
double num[]=new double[1000];
int n;
double average,median;
n=getdata(num);
sortdata(num,n);
average=getAverage(num,n);
median=getMedian(num,n);
printdata(num,n,average,median);
}
public static void printdata(double num[],int n,double average,double median)
{
int i;
System.out.print("The sorted numbers are");
for(i=0;i<n;i++)
{if(i ==0)
System.out.println();
System.out.print(num[i]+"\t");
}
System.out.println();
System.out.println("Range: ["+num[0]+", "+num[n-1]+"]");
System.out.println("Average: "+average);
System.out.println("Median: "+median);
}
public static double getMedian(double num[],int n)
{
if(n%2==0)
return (num[n/2]+num[n/2-1])/2.;
else
return num[n/2];
}
public static double getAverage(double num[],int n)
{int i=0;
double sum=0,average;
for(i=0;i<n;i++)
sum+=num[i];
average=sum/n;
return average;
}
public static int getdata(double num[])throws FileNotFoundException
{
String filename;
int n,i;
Scanner input=new Scanner (System.in);
System.out.print("Enter name of file:");
filename=input.nextLine();
Scanner in=new Scanner(new File(filename));
n=in.nextInt();
for(i=0;i<n;i++)
num[i]=in.nextDouble();
return n;
}
public static void sortdata(double num[],int n)
{int i,j;
double t;
for(i=0;i<n-1;i++)
for(j=i+1;j<n;j++)
if(num[i]>num[j])
{t=num[i];
num[i]=num[j];
num[j]=t;
}
}
}
