如何在Java中创建自动更正，以便在用户键入时替换用户输入？

import java.util.HashMap;
import java.util.Map;

public class AutoCorrector {
    private Map<String, String> corrections;

    public AutoCorrector() {
        corrections = new HashMap<>();
        // 添加需要自动更正的词汇和对应的替换词汇
        corrections.put("teh", "the");
        corrections.put("mispell", "misspell");
        // 添加更多的自动更正规则
    }

    public String correct(String input) {
        String[] words = input.split(" ");
        StringBuilder correctedInput = new StringBuilder();

        for (String word : words) {
            String correctedWord = corrections.getOrDefault(word.toLowerCase(), word);
            correctedInput.append(correctedWord).append(" ");
        }

        return correctedInput.toString().trim();
    }

    public static void main(String[] args) {
        AutoCorrector autoCorrector = new AutoCorrector();
        String userInput = "teh mispell in this centence";
        String correctedInput = autoCorrector.correct(userInput);
        System.out.println("User Input: " + userInput);
        System.out.println("Corrected Input: " + correctedInput);
    }
}
