在 Java 中创建随机字符时无法解决 class

Question

正如标题所述，当我尝试编译以下代码时遇到问题：

public class TestRandomCharacter {
  
    // main method
  
    public static void main(String[] args) {
    final int NUMBER_OF_CHARS=175;
    final int CHARS_PER_LINE=25;
 
     
    // print random characters between 'a' and 'z', 25 chars per line
    
    for (int i = 0; i < NUMBER_OF_CHARS; i++) {
      char ch =(RandomCharacter.getRandomLowerCaseLetter());
      if ((i + 1) % CHARS_PER_LINE == 0)
        System.out.println(ch);
      else
        System.out.print(ch);
    }

  }

}

char ch =(RandomCharacter.getRandomLowerCaseLetter())是我遇到问题的地方。 我尝试了 Random utils 的一些变体，但无济于事。 也许我已经走远了？ 非常感谢任何反馈。

you should integrate this class in your project https://github.com/jsquared21/Intro-to-Java-Programming/blob/master/Exercise_06/Exercise_06_38/RandomCharacter.java
