How do you store fingerprints in java?
Java has no built-in framework for dealing with biometric data, fingerprints included. If you wanted to build your own class, it would be sensible to store the information in the same way your fingerprint scanner passed it on. If the scanner gives you an image, store the image. If the scanner gives you a bunch of numbers, store a bunch of numbers.
How do you get double numbers from keyboard in java?
import java.util.*; public class Example { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Please enter a Double:"); double numDouble = in.nextDouble(); } }
Java program to arrange any numbers in ascending order using scanner classes?
To arrange numbers in ascending order using Java, you can utilize the Scanner class to read input from the user and then sort the numbers using an array. Here's a simple example: import java.util.Arrays; import java.util.Scanner; public class AscendingOrder { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter the number of elements: "); int n = scanner.nextInt(); int[] numbers = new int[n]; System.out.println("Enter the numbers:"); for (int i = 0; i < n; i++) { numbers[i] = scanner.nextInt(); } Arrays.sort(numbers); System.out.println("Numbers in ascending order: " + Arrays.toString(numbers)); scanner.close(); } } This program collects a specified number of integers from the user, sorts them using Arrays.sort(), and then displays the sorted list.
