Hi,

The code for sum of even numbers in java is given below:

import java.util.*;

import java.lang.*;

public class Jtp{

static int fun(int n)

{

int i, sum = 0;

for (i = 2; i <= n; i+=2) {

sum += i;

}

return sum;

}

public static void main(String argc[])

{

System.out.println("Enter any number: ");

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

System.out.println("sum of all even numbers from 1 to " + n + " is :" + fun(n));

}

}

Hope it helps.
