adding even numbers only java code example

Example 1: Java program to find the sum of all even numbers from 1 to 10

int sum = 0;
for (int i = 1; i <= 10; i++) {
// Logic for sum of EVEN
	if (i % 2 == 0) {
		sum = sum + i;
		}
}
System.out.println("Sum of all even from 1 to 10 is: " + sum);

Example 2: how to output sum of even numbers in java between two user values

//import classes
import java.util.*;

public class chapter5no9
{
    static Scanner console = new Scanner(System.in);

    public static void main(String[] args)
    {

    //Part A
    int firstNum;
    int secondNum;
    int sumEven;

    System.out.println("Please enter an integer: ");
    firstNum = console.nextInt();

    System.out.println("Please enter another integer less than the first integer: ");
    secondNum = console.nextInt();

    //Part B
    if (firstNum < secondNum)
    {
        System.out.print("Your second number is greater than the first.  So Please re-enter: ");
        secondNum = console.nextInt();
    }
    else
    {
        System.out.print("Odd Numbers: ");
        firstNum++;
        while (firstNum > secondNum)
        {
            if (secondNum % 2 != 0)
            {
                System.out.print(" " + secondNum);
            }
            secondNum++;
        }

        System.out.println();
        System.out.print("Sum of Even Numbers: ");
        firstNum++;
        while (firstNum > secondNum)
        {
            if (secondNum % 2 != 0)
            {
                System.out.print(" " + secondNum);
            }
            secondNum++;
        }
    }
}

Example 3: java program to add two numbers using method

// addition program in java
import java.util.Scanner;
public class AddTwoNumbers
{
   public static void main(String[] args)
   {
      int num1, num2, sum;
      Scanner sc = new Scanner(System.in);
      System.out.println("First number : ");
      num1 = sc.nextInt();
      System.out.println("Second number : ");
      num2 = sc.nextInt();
      sum = addTwo(num1, num2);
      System.out.println("Sum : " + sum);
      sc.close();
   }
   public static int addTwo(int a, int b)
   {
      int sum = a + b;
      return sum;
   }
}
