如何在Java中随机生成一个indefenitly直到它尊重一个条件？

Question

Do you have an idea how to generate a random Object until an object doesn't respect a condition ?

我试过像这样。

//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，这听起来并不好。有什么建议吗？

试试 do-while 襻

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)))
