Question

Write a program with loop that lets the use enter a series of integers. The user should enter -1 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.

Answer 1

import java.util.ArrayList;

import java.util.Scanner;

import java.util.Collections;

public class num6 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int num;

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

do{

System.out.println("Enter a series of integers. To quit enter -1");

num = in.nextInt();

al.add(num);

}while(num>=0);

System.out.println( "The minimum Value: " + Collections.min(al) );

System.out.println( "The Maximum Value: " + Collections.max(al) );

}

}

Step-by-step explanation:

1. Create an ArrayList Object
2. Prompt user to continually enter integer values (while numbers is >=0)
3. Store the values in the ArrayList
4. Use the Collections.min Method to print the smallest value
5. Use Collections.max Method to print the largest value
