Java-02，计算1+3+5+7+......+99的值

public class HelloWorld{
    public static void main(String[] args) {
        long result = 0;
        long f = 1;
        for(int i = 1; f <= 99; i++){
            result += f;
            f = f + 2;
        }
        System.out.printf("result = %d\n",result);
    }
}
