一些常用的随机实现

if (RandomUtil.randomInt(10) > 2)
{
// 1.高频
}else if (RandomUtil.randomInt(10) > 3)
{
// 2
} else if (RandomUtil.nextBoolean())
{

}

int result = RandomUtil.randomInt(3);
switch (result)
{
case 0:
//搜索帮派
        csGuildSearch();
        break;
    case 1:
//请求帮派列表和申请帮派
        csGuildList();
        break;
    case 2:
//创建帮派
        csGuildCreate(getClientObject().getActorID());
        break;
    default:
break;
}

int rankId = 0;
int[] keys = DictRankDetailData.getServerTypeKeys();
if (keys.length > 0)
{
int random1 = RandomUtil.randomInt(keys.length);
    TIntArrayList records = DictRankDetailData.getRecordsByServerType(keys[random1]);
    int randomRankIndex = RandomUtil.randomInt(records.size());
    if (randomRankIndex > 0)
    {
        rankId = records.get(randomRankIndex);
    }
}
