eclipse断点的使用---for循环举例

 1 package day03;
 2 
 3 public class exer12 {
 4 
 5     public static void main(String[] args) {
 6         // 10以内的奇数之和
 7         
 8         int num = 0;
 9         for(int i = 1;i<=10;i++) {
10             if(i%2 == 1) {
11                 num = num +i;
12                 System.out.println("奇数:"+i);
13             }
14         }
15         System.out.println("10以内的奇数之和为"+num);
16 
17     }
18 
19 }
