我尝试在线查看并没有罚款任何有用的东西，我正在制作一个刽子手游戏，我想要一个字符串，从一大堆的单词中得到一个随机的单词，我想如果我把我的所有单词变量像word1，并创建一个等于word加上随机整数Ex的String。 String randomWord = word+randomInt;然后创建了一个随机数生成器，它将生成一个随机数并将其设置为randomInt，但是当我这样做时，它告诉我该单词不是变量，我试着将这些东西放在整个语句中，但是它不起作用，我怎么能这样做？

现在唯一的相关部分是第一堆线，剩下的就是整个游戏功能，我没有在actionListener到randomWord中设置if语句，因为我不会这样做直到randomWord正常工作，我怎么能解决这个问题？

String[] myWords = { "alpha", "beta", "meringue" };
String randomWord = myWords[random.nextInt(myWords.length)];
答案 1 :(得分：1)
以下代码无法编译的原因是因为您从未创建任何名为word的对象。
String word = "someRandomWordHere";
String randomWord = word + randomInt;
以下是解决此问题的方法：
1.) Turn your 3 final word variables into arrays.
2.) Loop through the arrays.
3.) Implement random in such a way that it picks one of the 3 words you've specified.
4.) Set your randomWord equal to the newly randomized word.
5.) Continue
编辑：
public static void main(String[] args) {
Random r = new Random();
int randomInt = r.nextInt(3);
String words[] = { "lude", "lose", "stop" };
String randomWord = words[randomInt];
System.out.println(randomWord);
}

你应该把所有的话都放在这样的数组中：
String words = {"word1","word2","word3"};
创建随机生成器对象
Random randomWordGenerator = new Random();
每当你想得到一个随机字时，只需生成一个随机整数，并使用这个值作为字母数组中的索引值，如下所示：
int index = randomWordGenerator.nextInt(words.length);
现在这应该给你一个随机的词：
String randomWord = words[index];
