Hello, can any one please help me in problem 2 of project euler?

Here is the problem::::::::::::

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

My Code:

import java.io.*;

class pro2

{

public static void main(String args[])

{

int a=1,b=2,c=0,sum=0;

while(c<=4000000)

{

c=a+b;

if((c%2)==0)

{sum+=c;}

a=b;

b=c;

}

System.out.println(sum);

}

}
