请问如何在固定几个字符串中随机选择一个?

[YPFARSEER]

假如,我有11个固定的字符串, smallCaveA smallCaveB .....等等,

randomCave.setExit("blackhole",smallCaveC);
这个语句是从 randomCave到smallCaveC


假如我需要从randomCave随机到任意一个smallCaveA,B,C,D... 我需要怎么做?

[cursor_wang]

是不是这样．我理解是这样．

class RandomTest{
	public static void main(String[] args){
		String[] str={"smallCaveA","smallCaveB","smallCaveC","smallCaveD","smallCaveE",
		              "smallCaveF","smallCaveG","smallCaveH","smallCaveI","smallCaveJ","smallCaveK"};
		String temp=RandomTest.randomCave(str);
		System.out.println(temp);
	}
	
	public static String randomCave(String str[]){
		int m=(int)(Math.random()*str.length);
		System.out.println(str[m]);
		return str[m];
	}
}

给字符串放到数组中，然后以数组的长度作为随机种子，随机出数组的位置，根据位置获得相应的字符串

[fastunit]

Random r = new Random();
int i = r.nextInt(11);//返回0~10

如果是随即取的话,我建议不用nextInt()来做,说老实话nextInt()的随即性不强,这是他的内部算法所限定的.
用(Math.round(Math.random()*10) + 9 ) %10这样的算法随即性会大些,个人观点...
