I’m just wondering what is wrong with my code. If I run this code I get an error “java.utilNoSuchElementException” null?

Question

i get this error on line java:18 which is the “population[i] = inputFile.nextInt();
I have created a file on my computer named “provinceData” as a text file with some contents inside.

Answer 1

Can you show your provinceData.txt?

Answer 2

String[] names = new String[10]
int[] population = new int[10];

try

String[] names;
int[] population;

Answer 3

Still error? Try above

Answer 4

i think because the scanner didnt find any file in C:/temp/provinceData.txt

Answer 5

you cant read name with next() because you have names with space so use nextLine()
I added two }} at the end of your code
and I open file with different way, but path is correct way too
this works for me:

...
File file = new File ("input.txt");
Scanner inputFile = new Scanner(file);
// dynamically allocate the array
String [] names = new String [10];
int[] population = new int[10];

i = 0;
while (inputFile.hasNext()) {
names[i] = inputFile.nextLine(); //nextLine()
population[i] = inputFile.nextInt();

// dummy read to discard the \n for reading the next province name
inputFile.nextLine();
//System.out.println(names[i]+" "+population[i]);
i++;
}
} } //added
