java – 我需要使用输入文件将句子转换为pig latin

2019年7月22日 274次阅读

我应该编写一个程序,将整个短语转换为
pig latin.它应该从文件中读取短语,然后翻译并以猪拉丁语形式打印出来.

这必须从文件中读取文本.
键盘应该没有输入.

这是我的示例文件文本：

This is a test

Here is a second line

and a third

输出应该是原始短语,然后是猪拉丁语版本.两个版本都应该在输出中用引号括起来.

“This is a test” in pig latin is “is-Thay is-way a-way est-tay “

“Here is a second line” in pig latin is “ere-Hay is-way a-way
econd-say ine-lay “

“and a third” in pig latin is “and-way a-way ird-thay “

我已经改变了一些东西,现在我可以输出一个句子,但不能超过一个.我如何获得多行输出.如何让扫描仪进入下一行？

我现在拥有以下内容：

import java.util.Scanner;
import java.io.*;

public class pigLatin2 {

    public static void main(String[] args) throws FileNotFoundException {
        Scanner input = new Scanner(new File("phrases.txt"));

        while (input.hasNextLine()) {
            String line = input.nextLine();
            System.out.print("\"" + line + "\"" + " in pig latin is \"");
            Scanner words = new Scanner(line);
            while (words.hasNext()) {
                String word = words.next();
                String pigLatin = pigLatinWord(word);
                System.out.print(pigLatin + " ");
            }
            System.out.println("\"");
        }
    }


    public static String pigLatinWord(String s) {
        String pigWord;
        if (isVowel(s.charAt(0))) {
            pigWord = s + "-way";
        } else if (s.startsWith("th") || s.startsWith("Th")) {      // or (s.toUpperCase().startsWith("TH"))
            pigWord = s.substring(2) + "-" + s.substring(0,2) + "ay";
        } else {
            pigWord = s.substring(1,s.length()) + "-" + s.charAt(0) + "ay";
        }
        return pigWord;
    }


    public static boolean isVowel(char c) {
        String vowels = "aeiouAEIOU";
        return (vowels.indexOf(c) >= 0);    // when index of c in vowels is not -1, c is a vowel
    }
}

在拉丁语中输出“这是一个测试”是“is-Thay is-way a-way est-tay”

最佳答案 你在这里只读一个字：

    Scanner words = new Scanner(line);
    String word = words.next();
    String pigLatin = pigLatinWord(word);

试试这个：

    Scanner words = new Scanner(line);
    String pigLatin = "";
    while(words.hasNext()){
        String word = words.next();
        pigLatin += pigLatinWord(word) + " ";
    }

如果您对字符串连接有所了解,请在此处使用StringBuilder.
