# Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive.

LANGUAGE: JAVA

CHALLENGE:

Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates, it prints out, on a line by itself and separated by spaces, the sum of all the even integers read, the sum of all the odd integers read, a count of the number of even integers read, and a count of the number of odd integers read, all separated by at least one space. Declare any variables that are needed.

ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input.

SOLUTION:

int number = 1; int oddTotal, evenTotal, oddCount, evenCount; oddTotal = evenTotal = oddCount = evenCount = 0; while (stdin.hasNextInt() && number > 0) { number = stdin.nextInt(); if (number % 2 == 0 && number > 0) { evenTotal += number; evenCount += 1; } if (number % 2 != 0 && number > 0) { oddTotal += number; oddCount += 1; } } System.out.println(evenTotal + " " + oddTotal + " " + evenCount + " " + oddCount);
