Question

我是Java的初学者，我正在开展一个需要我们制作句子句子的项目。我遇到的问题是，即使在找到带有形容词的第一个char匹配的名词后，while循环也不会停止。这就是我到目前为止所做的：

import java.io.*;
import java.util.*;

public class WordList {
int count = 1;
String Adj = randomAdj();
String Noun = randomNoun();


public String randomAdj() {

    ArrayList<String> Adjs = new ArrayList<String>();
    Scanner adj = null;
    try {
        adj = new Scanner(new File("adj.txt"));
    } catch (Exception e) {
        System.out.println("Couldn't not open file");
    }
    while (adj.hasNext()) {
        Adjs.add(adj.next());
    }
    adj.close();

    Random rand = new Random();
    String randomAdj = Adjs.get(rand.nextInt(Adjs.size()));
    System.out.printf("%s ", randomAdj);
    return randomAdj;
}

public String randomNoun() {

    ArrayList<String> Nouns = new ArrayList<String>();
    Scanner noun = null;
    try {
        noun = new Scanner(new File("noun.txt"));
    } catch (Exception e) {
        System.out.println("Couldn't not open file");
    }
    while (noun.hasNext()) {
        Nouns.add(noun.next());
    }
    noun.close();
    Random rand = new Random();
    String randomNoun = Nouns.get(rand.nextInt(Nouns.size()));
    //System.out.printf("%s ", randomNoun);
    return randomNoun;
}

public void randomWordStartingWith() {


    while(Adj.charAt(0) != Noun.charAt(0))
    {
        count++;
        //System.out.println(Adj + " " + randomNoun() + " " + count);
        randomNoun();

    }
    System.out.println(Adj + " " + Noun + " " + count);

}

}

Answer 1

问题是你的循环是永远不会更新Noun（或Adj）：

while(Adj.charAt(0) != Noun.charAt(0))
{
    count++;
    Noun = randomNoun();
}

我删除了注释行：

//System.out.println(Adj + " " + randomNoun() + " " + count);

如果您要取消注释此行，则应使用Noun的值，而不是再次调用randomNoun() - 并且可能将其放在Noun =行之后。
