Question

java循环结构

int p[] = {11, 12, 13, 14, 15, 16, 17, 18}, i = 0, j = 0; while (i++< 7){//i=7还可以循环吗? if (p[i] % 2 == 0) j += p[i]; } System.out.print(j); 上面这段代码运行后的结果是60;我的疑点是:当i循环到赋值为7的时候,已经不能满足循环条件<7了,为什么循环没有结束?

Answer 1

int
p[]
=
{11,
12,
13,
14,
15,
16,
17,
18},
i
=
0,
j
=
0;
while
(++i<
7){//i=7还可以循环吗?
if
(p[i]
%
2
==
0)
j
+=
p[i];
}
System.out.print(j);
这样就不等于60了！因为++i先加1再判断，而i++是先判断再加1.
