java 福利**选6 这段代码 能随机选出6个不重复的号码,但是费源带弹幕视频播放器源码 不能排除0;求大神指教,修改!彩票a彩同花顺t 0分时源码
按你的手机逻辑,出现0有2种情况:1、端源随机出g==0;可以用 an[i]=g+1; 解决。码ja免码(另外rd.nextInt(n)的费源取值范围是0~n-1)
2、随机出以前相同的彩票a彩数字,但你的手机处理办法是不管了,直接continue,端源二次解析源码 切换线路所以中间就空出一个数字未加到数组an中,码ja免码默认等于0。费源短线一般选股源码可用 i--; 解决
找你的代码稍微改动即可:
for (int i = 0; i < an.length; i++) {g = rd.nextInt(n);
if (bl[g]) {
i--;
continue;
}
an[i] = g+1;
bl[g] = true;
}
