Write a Java program that prompts the user to enter a sequence of non-negative numbers (0 or more), storing them in an ArrayList, and continues prompting the user for numbers until they enter a negative value. When they have finished entering non-negative numbers, your program should return the mode (most commonly entered) of the values entered.

Answer: provided in explanation segment

Explanation:

the code to carry out this program is thus;

import java.util.ArrayList;

import java.util.Scanner;

public class ArrayListMode {

 

public static int getMode(ArrayList<Integer>arr) {

      int maxValue = 0, maxCount = 0;

      for (int i = 0; i < arr.size(); ++i) {

          int count = 0;

          for (int j = 0; j < arr.size(); ++j) {

              if (arr.get(j) == arr.get(i))

                  ++count;

          }

          if (count > maxCount) {

              maxCount = count;

              maxValue = arr.get(i);

          }

      }

      return maxValue;

  }

public static void main(String args[]){

  Scanner sc = new Scanner(System.in);

  ArrayList<Integer>list= new ArrayList<Integer>();

  int n;

  System.out.println("Enter sequence of numbers (negative number to quit): ");

  while(true) {

      n=sc.nextInt();

      if(n<=0)

          break;

      list.add(n);

  }

  System.out.println("Mode : "+getMode(list));

}

}

⇒ the code would produce Mode:6

cheers i hope this helps!!!!
