java流程控制之 for循環 1到100的奇偶數和

package struct;

public class Demo05 {
    public static void main(String[] args) {
        int oddSum = 0;
        int evenSum = 0;

        for (int i = 0; i <= 100; i++) {
            if (i % 2 != 0) {
                oddSum += i;
            } else {
                evenSum += i;
            }
        }
        System.out.println("奇數和"+oddSum);//2500
        System.out.println("偶數和"+evenSum);//2550
    }
}
