***Please add on/modify the existing code below with requirements #3 below***
3: Create a method (called DataSave) that will write data to a file. This method will accept an array of Person objects.
The method will open the file (data.txt), and place each person object information (from the array) into the file (1 per line).
Data items you are putting into each line of the file are:
FName (string)
LName (string)
age (int)
married status (boolean).
** You may assume there are appropriate get methods for your use.
***current java code***
import java.io.File; import java.io.FileNotFoundException; import java.util.Arrays; import java.util.InputMismatchException;
import java.util.Scanner;
public class Test {
public static void main(String[] args) throws FileNotFoundException {
int ar[] = new int[10]; // array to contain int value
// scanner to take input Scanner sc = new Scanner(new File("data.txt"));
int input = 0;
for (int i = 0; i < ar.length; i++) { // for length of array
try {
input = sc.nextInt();// reading values from text file line by line
if (input == 0) { // if input is zero
throw new IllegalValueException(); // Throw this exception
}
}
catch (IllegalValueException e) {
// filling array with 1 Arrays.fill(ar, 1);
System.out.println(e);// showing error
break;// breaking out of the loop
}
catch (InputMismatchException e) { // for input other then int
System.out.println("Input value mismatched"); // give warning and continue
Arrays.fill(ar, 0);// filling array with 0
System.out.println(e);// showing error
break;// breaking out of the loop
}
ar[i] = input; // set input to the array // for showing array values System.out.println("Array contains: " + Arrays.toString(ar)); } // for showing array values System.out.println("Array contains: " + Arrays.toString(ar)); sc.close();// closing the file
}
}
class IllegalValueException extends Exception {
IllegalValueException() {
super();
}
}
