I have asked a question like this before but am now getting a new error.
I am trying to take a file of ages and names (age, name) that the user put in through the console and sort them in ascending order. I keep running into problems and getting errors when I am am running it.
The file looks like this:
(56, Suresh) (89, Mahesh) (81, Shyam) (92, Vikas) (84, Shloka) (62, Nalini) (71, Ahbi)
Scanner inputFile = new Scanner(System.in);
System.out.println("File to read from");
File file = new File (inputFile.nextLine());
inputFile = new Scanner(file);
ArrayList<ponySort> nameAge = new ArrayList<ponySort>();
String currentLine = inputFile.nextLine();
while (currentLine != null) {
String[] parts = currentLine.split("(?<=\\)) (?=\\()");
for (String part : parts) {
String input = part.replaceAll("[()]", "");
int age = Integer.parseInt(input.split(", ")[0]);
String name = input.split(", ")[1];
nameAge.add(new ponySort(name, age));
currentLine = inputFile.nextLine();
}
}
This is the error message that I am getting when I am running my code:
Exception in thread "main" java.util.NoSuchElementException: No line found
at java.util.Scanner.nextLine(Scanner.java:1540)
at sortFile.main(sortFile.java:26)
Now I thought maybe if I changed the currentLine = inputFile.nextline() (at the bottom of my while) to - currentLine = inputfile.next(), that it might do something but all that happened was that I got another error. This time it said:
Exception in thread "main" java.lang.NumberFormatException: For input string: "Nalini"
at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:580)
at java.lang.Integer.parseInt(Integer.java:615)
at sortFile.main(sortFile.java:23)
If anyone could help me so that it just reads through the file correctly that would be great. I have a toString and everything else in order so that it prints out the ages and names in ascending order.
