Use a do..while loop to write a java program that asks the user to input a sequence of integers. Then, it will find and display each of the following:

The number of integers.
The sum of the integers.
The number of odd integers.
The number of even integers.

Hint: Use (-1) as a sentinel value to end the sequence and skip an endless loop

import java.util.Scanner; 
public class Exercise3{ 
public static void main(String[] args){ 
 Scanner input = new Scanner(System.in); 
int number, odd = 0, even = 0, sum = 0, count = 0; 
do { 
 System.out.println("Enter an integer :"); 
 number = input.nextInt(); 
 if (number == -1) 
 break; 
 
 if (number % 2 == 0) 
 even++; 
 else 
 odd++; 
 sum += number; 
 count++; 
} while (true); 
System.out.println("Number of integers is " + count); 
System.out.println("Sum of integers is " + sum); 
System.out.println("Number of odd integers is " + odd); 
System.out.println("Number of even integers is " + even); 
} 
}
