单击随机按钮时如何显示相同位置的不同字符串？

Question

如何在单击随机按钮时显示具有相同位置的不同字符串，因此当字符串被随机化时，word 和 word2 在不同的文本视图中显示相同的位置数据。这几天一直在找资料，还没找到答案。我很困惑这样做你能帮我吗？这是我的 Java 文件。

Adapter.java

package com.word.game;
import java.util.Random;
public class Adapter {

public static final Random RANDOM = new Random();
public static final String[] WORDS = {"RUN",
"WALK",
"CRY",
"SUGAR",
"SALT",
"RAIN",
"NOVEMBER"};

public static final String[] WORDS2 = {"FAST",
"RELAX",
"TEARS",
"DRINK",
"RECIPERS",
"WATER",
"CALENDAR"};


public static String randomWord2() {
    return WORDS2[RANDOM.nextInt(WORDS2.length)];
}

public static String randomWord() {
    return WORDS[RANDOM.nextInt(WORDS.length)];
}

public static String shuffleWord(String word) {
    if (word != null  &&  !"".equals(word)) {
        char a[] = word.toCharArray();

        for (int i = 0; i < a.length; i++) {
            int j = RANDOM.nextInt(a.length);
            char tmp = a[i];
            a[i] = a[j];
            a[j] = tmp;
        }

        return new String(a);
    }

    return word;
}

}

Answer 1

如果你想 return 相同大小的不同数组中的相同位置，

试试这个

public static String randomWord2(int pos) {
    return WORDS2[pos];
}

public static String randomWord(int pos) {
    return WORDS[pos];
}

public static int randomNum() {
    return RANDOM.nextInt(WORDS.length);
}

当您调用 randomWord() 和 randomWord2() 时，首先获取随机位置并将其传递给方法

int pos= randomNum();
word1=randomWord(pos);
word2=randomWord2(pos);
