java - 如何无限地生成随机数，直到它符合Java中的条件？

Question

您是否知道如何生成随机对象，直到对象不满足条件为止？

我尝试过这样的:

//Btw getTeam1() is a hashMap of Integer,Fighter (a type of objects that I use)
//randomIndex
Object randomName = this.getTeam1().keySet().toArray()[new Random().nextInt(this.getTeam1().keySet().toArray().length)];
while(this.getTeam1().get(randomName).dontVerifyMyConditionBlabla) {
        randomName = this.getTeam1().keySet().toArray()[new Random().nextInt(this.getTeam1().keySet().toArray().length)];
}

但显然，听起来不太好。有什么建议吗？

Answer 1

尝试do-while循环

verifyMyCondition(){
   //proccess and return true or false
}

do
{
     randomName = this.getTeam1().keySet().toArray()[new Random().nextInt(this.getTeam1().keySet().toArray().length)];
}while(verifyMyConditionthis.getTeam1().get(randomName)))
