使用Java创建具有相似名称的文件,而不覆盖现有文件

import java.io.File;
import java.io.IOException;

public class FileCreator {

    public static void main(String[] args) {
        String baseFileName = "example.txt";
        String availableFileName = generateFileName(baseFileName);
        createFile(availableFileName);
    }

    private static String generateFileName(String baseFileName) {
        File file = new File(baseFileName);
        int counter = 1;
        while (file.exists()) {
            String fileNameWithSuffix = String.format("%s_%d", baseFileName, counter);
            file = new File(fileNameWithSuffix);
            counter++;
        }
        return file.getName();
    }

    private static void createFile(String fileName) {
        try {
            File file = new File(fileName);
            if (file.createNewFile()) {
                System.out.println("File created: " + fileName);
            } else {
                System.out.println("File already exists.");
            }
        } catch (IOException e) {
            System.out.println("An error occurred while creating the file.");
            e.printStackTrace();
        }
    }
}
