在没有繁忙工作的情况下在Java中模拟拼写错误

String wrongWord = "wrong";
String wrongUpper = wrongWord.substring(0, 1).toUpperCase() + wrongWord.substring(1);
System.out.println(wrongUpper); // 输出 "WorNG"

String wrongWord = "wrong";
String wrongChar = " ";
String wrongReplace = wrongWord.replace(wrongChar, '*');
System.out.println(wrongReplace); // 输出 "*****"

import java.util.Random;

public class Main {
  public static void main(String[] args) {
    String wrongWord = "wrong";
    Random random = new Random();
    StringBuilder wrongBuilder = new StringBuilder();

    for (int i = 0; i < 5; i++) {
      int randomIndex = random.nextInt(wrongWord.length());
      wrongBuilder.append(wrongWord.charAt(randomIndex));
    }

    String wrongRandom = wrongBuilder.toString();
    System.out.println(wrongRandom); // 输出 "rgwitr"
  }
}
