java - 如何在遵守Java条件的前提下无限生成随机变量？

您是否有一个想法，如何在对象不遵守条件之前生成随机对象？

我这样尝试过：

//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)];
}

但是显然，这听起来并不好。有什么建议吗？

最佳答案

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)))
