i%3==0就说明能被3整除,for循环每选出1-100中一个能被3整除的数就加到sum里,最后输出总和sum
所以应该从循环外放到循环内intbegin=1;intend=100;// 退出条件不应该是1-100,循环99次。
do while 语..class Test7{public static void main(String[] args){int even = 2;//1-100int num = 0;do{even += 2;num += even;}while(even<=100);System.out.println("偶数总和="+num);}}
14.下面的代码中,sum的结果是: public class Demo2 { public static void main (Stringargs[]) { int sum=0, i=0; do{ sum+=i; //累加i的值 i++; }while(i<=100) ; //当i小于等于100 System. out.println("从1到100的整数和为: "+sum); ...
