猪拉丁程序,切换/否则错误

Question

//我需要帮助我的其他if语句.如果单词以元音开头,则添加到单词末尾的方式.如果这个单词以辅音开头,那么你可以将辅音放在最后并添加一个.

我的问题是,如果我的第一个字母带有元音一个字,它会像一个辅音一样贯穿其中.如果我输入"是",我会得到"arewayreaay"而不是"areway".

public class piglatin {
    public static void main(String[] args) {
        String str = IO.    readString();    
        String answer = "";

        if(str.startsWith("a"))
            System.out.print(str + "way");

        if(str.startsWith("e"))
            System.out.print(str + "way");

        if(str.startsWith("i"))
            System.out.print(str + "way");

        if(str.startsWith("o"))
            System.out.print(str + "way");

        if(str.startsWith("u"))
            System.out.print(str + "way");
        else{
            char i = str.charAt(0);
            answer = str.substring( 1, str.length());
            System.out.print(answer + i + "ay");
        }
    }
}

Answer 1

if(str.startsWith("a") || str.startsWith("e") || str.startsWith("i") ... (and so on)) {
  System.out.print(str + "way"); 
} else{
  char i = str.charAt(0);
  answer = str.substring( 1, str.length());
  System.out.print(answer + i + "ay");
}

或者if/else if/else

说明:

//  combine all the if blocks together .. if you dont it checks for vowel 'a' and prints
//  'areay' then it checks for vowel 'u' and enters the else block .. where it again
//  operates on 'are' (check immutability of strings) gets charAt(0) i.e 'a' and prints
//  'rea' and since you concatenated 'ay' ... the final output = 'arewayreaay'
