1. Keep scanning from user until user enters -1
2. Store the numbers in ascending order as the user enters
3. Have a loop to check if the number where the number should be and insert it in that index
4. Print out the final array.
import java.util.ArrayList;
import java.util.Scanner;
public static void main(String ​[] args) {
ArrayList numbers = new ArrayList ();
System.out.println(“Enter numbers one after another. Once done enter -1”);
}

Answer 1

import java.util.ArrayList;
import java.util.Scanner;

public class Main {
public static void main(String [] args) {
ArrayList numbers = new ArrayList<>();
System.out.println("Enter numbers one after another. Once done enter -1");
Scanner scan = new Scanner(System.in);
int num = scan.nextInt();
while (num != -1) {
int index = 0;
for (int i = 0; i < numbers.size(); i++) {
if (numbers.get(i) < num) {
index++;
}
}
numbers.add(index, num);
num = scan.nextInt();
}
System.out.println("The final array is: " + numbers);
}
}
