解决方法

int total = 0; for (int i = 1; i <= 5; i++) { total = total + i; System.out.println(total); }

好像还没学到for循环情况下的笨方法 int a = 1; int b = 2; int c = 3; int d = 4; int e = 5; System.out.println(a); System.out.println(a+b); System.out.println(a+b+c); System.out.println(a+b+c+d); System.out.println(a+b+c+d+e);

public class Solution { public static void main(String[] args) { //在此编写你的代码 int x,y ; for(x=0,y=1;y <= 5;y++){ x = x + y; System.out.println(x); } } }

int num = 0; for(int i = 1;i <= 5;i++){ num = i + num; System.out.println(num); } 抛砖引玉，希望大神能指导，不胜感激。
