java利用集合类随机产生26个英文字母软键盘的代码

可以尝试如下代码：

import java.util.*;

public class KeyboardGenerator {
    public static void main(String[] args) {
        List<Character> letters = new ArrayList<>();
        // Add 26 English letters to list
        for (char c = 'a'; c <= 'z'; c++) {
            letters.add(c);
        }
        Collections.shuffle(letters);
        
        // Generate keyboard layout
        System.out.println("QWERTY keyboard layout:");
        System.out.println("-----------------------");
        System.out.println("| " + letters.get(0) + " | " + letters.get(1) + " | " + letters.get(2) + " | " + letters.get(3) + " | " + letters.get(4) + " | " + letters.get(5) + " | " + letters.get(6) + " | " + letters.get(7) + " | " + letters.get(8) + " | " + letters.get(9) + " | " + letters.get(10) + " | " + letters.get(11) + " | ");
        System.out.println("| " + letters.get(12) + " | " + letters.get(13) + " | " + letters.get(14) + " | " + letters.get(15) + " | " + letters.get(16) + " | " + letters.get(17) + " | " + letters.get(18) + " | " + letters.get(19) + " | " + letters.get(20) + " | " + letters.get(21) + " | " + letters.get(22) + " | " + letters.get(23) + " | ");
        System.out.println("| " + letters.get(24) + " | " + letters.get(25) + " |                     | " + letters.get(26) + " | " + letters.get(27) + " | " + letters.get(28) + " | " + letters.get(29) + " | " + letters.get(30) + " | " + letters.get(31) + " |                     | # | ");
        System.out.println("-----------------------");
    }
}

这个代码将 `a` 到 `z` 的 26 个字母放入一个 `ArrayList` 中，然后使用 `Collections.shuffle` 方法打乱顺序，最后按照 QWERTY 键盘布局将字母输出。
