Java循环练习：求1+(1+2)+(1+2+3)+(1+2+3+4)+...(1+2+3+..+10)的和

import java.util.Scanner;
public class ChapterExercise09 {


	public static void main(String[] args) {
        //计算 1-100值的和
		int sum = 0;
		int result = 0;
		for(int i =1; i<=100; i++){

			sum = sum + i;
            // 核心代码：将sum的值 重新累加给result
			result =result + sum;

		}
		System.out.println(result);     //171700
		
}
