A program (Java) that outputs the sum of odd and even numbers in an array

About the procedure

This is a program that finds the sum of odd numbers and the sum of even numbers in an array and displays the result. Follow the procedure below.

1. Define variables to manage an array of numbers
2. Define variables to manage even and odd numbers
3. Describe the iterative process with a for statement
4. Describe odd and even conditional branches in the if statement
5. Description for outputting the result

Define variables to manage an array of numbers

Main.java

class Main {
 public static void main(String[] args) {
   //Substitute the given array of numbers for the variable numbers
   int[] numbers = {1, 4, 6, 9, 13, 16};
 }
}

Define variables to manage even and odd numbers

Main.java

class Main {
 public static void main(String[] args) {
   int[] numbers = {1, 4, 6, 9, 13, 16};
   //Define the variable oddSum and assign 0(This is odd)
   int oddSum = 0;
   //Define the variable evenSum and assign 0(This is an even number)
   int evenSum = 0;
 }
}

Describe iterative processing with a for statement

As a processing procedure, while issuing all the arrays with the for statement, conditional branching is done with the if statement. By writing as follows, each element of the array numbers is assigned to the variable number in order.

Main.java

class Main {
 public static void main(String[] args) {
   int[] numbers = {1, 4, 6, 9, 13, 16};
   int oddSum = 0;
   int evenSum = 0;
    //Repeat array numbers using for statement
   for (int number : numbers) {
  }
 }
}

Describe odd and even conditional branches in if statement

Let the description of (number% 2 == 0) determine whether it is an even number.

Main.java

class Main {
 public static void main(String[] args) {
   int[] numbers = {1, 4, 6, 9, 13, 16};
   int oddSum = 0;
   int evenSum = 0;
   for (int number : numbers) {
    //Describe conditional branch in if statement
     if (number % 2 == 0) {
      evenSum += number;
   } else {
      oddSum += number;
   }
  }
 }
}

Description for outputting the result

Describe it outside the for statement. If you write it in the for statement, it will be output every time you call each element of numbers.

Main.java

class Main {
 public static void main(String[] args) {
   int[] numbers = {1, 4, 6, 9, 13, 16};
   int oddSum = 0;
   int evenSum = 0;
   for (int number : numbers) {
    //Describe conditional branch in if statement
     if (number % 2 == 0) {
      evenSum += number;
   } else {
      oddSum += number;
   }
  }
  //Described outside the for statement
  System.out.println("The sum of odd numbers is" + oddSum + "is");
  System.out.println("The sum of even numbers" + evenSum + "is");
 }
}

That's it.
