我正在写一个猪拉丁语代码,如果单词中的第一个字母是辅音,如何让我的程序识别单词中的下一个元音的位置,我会被绊倒。然后它将单词的第一部分(直到第一个元音)移动到单词的末尾并随之打印出来。 (例如trees = eestray)
这是我现在的代码
// word is bringing in the string entered from the user
public static void translate(String word) {
String wordCap, pigLatin = "";
char vowels;
int lowest = 0, tempOne, tempTwo, tempThree, tempFour, tempFive;
wordCap = word.toUpperCase();
vowels = wordCap.charAt(0);
if (vowels == 'A' || vowels == 'E' || vowels == 'I' || vowels == 'O' || vowels == 'U') {
word = word + "way";
System.out.println(word);
}
else {
tempOne = wordCap.indexOf('A', 1);
if (lowest > tempOne && tempOne != -1) {
lowest = tempOne;
}
tempTwo = wordCap.indexOf('E', 1);
if (lowest > tempTwo && tempTwo != -1) {
lowest = tempTwo;
}
tempThree = wordCap.indexOf('I', 1);
if (lowest > tempThree && tempThree != -1) {
lowest = tempThree;
}
tempFour = wordCap.indexOf('O', 1);
if (lowest > tempFour && tempFour != -1) {
lowest = tempFour;
}
tempFive = wordCap.indexOf('U', 1);
if (lowest > tempFive && tempFive != -1) {
lowest = tempFive;
}
public static char vowel(String word) {
int start= 0, end= 0;
char vowels;
for (int i = 0; i < word.length(); i++) {
vowels = word.charAt(i);
if (vowels == 'A' || vowels == 'E' || vowels == 'I' || vowels == 'O' || vowels == 'U') {
end = i;
break;
}
}
return (char) end;
}
(在翻译方法中)
for (int i = 0; i<wordCap.length(); i++) {
if (vowel(wordCap.charAt(i))) {
vowels = wordCap.charAt(i);
}
}
现在的问题是元音方法不适用于方法类型。它说它必须是一个炭?
答案 0 :(得分:1)
让我试着为你缩短这种方法;)
尝试这样的事情:
private static final char[] vowels = {'a', 'e', 'i', 'o', 'u'};
public static String translate(String word) {
int start = 0; // start index of word
int firstVowel = 0;
int end = word.length(); // end index of word
for(int i = 0; i < end; i++) { // loop over length of word
char c = Character.toLowerCase(word.charAt(i)); // char of word at i, lower cased
if(Arrays.asList(vowels).contains(c)) { // convert vowels to a list so we can use List.contains() convenience method.
firstVowel = i;
break; // stop looping
}
}
if(start != firstVowel) { // if start is not equal to firstVowel, we caught a vowel.
String startString = word.substring(firstVowel, end);
String endString = word.substring(start, firstVowel) + "ay";
return startString+endString;
}
return word; //couldn't find a vowel, return original
}
这个片段的作用是迭代单词中的每个字符,将第一个元音的索引存储在firstVowel
变量中。然后,我们得到从firstVowel
到end
的每个字符;并将其存储在startString
中。然后,我们得到从start
到firstVowel
的每个字符;添加&#34; ay&#34;,并将其存储在endString
中。最后,我们将这些字符串连接在一起并返回它们,从而产生所需的输出。
我们可以使用System.out.println(translate("trees"));
编辑:没有数组,请求:
public static String translate(String word) {
char a = 'a';
char e = 'e';
char i = 'i';
char o = 'o';
char u = 'u';
int start = 0;
int firstVowel = 0;
int end = word.length();
for(int i = 0; i < end; i++) {
char c = Character.toLowerCase(word.charAt(i));
if(c == a || c == e || c == i || c == o || c == u) {
firstVowel = i;
break;
}
}
if(start != firstVowel) {
String startString = word.subString(firstVowel, end);
String endString = word.subString(start, firstVowel) + "ay";
return startString+endString;
}
return word;
}
正如您所看到的,数组缩短了很多东西!
如果您对Arrays.asList().contains()
电话感到迂腐,我们可以定义自己的电话:
public static boolean containsChar(char[] lookIn, char lookFor) {
boolean doesContainChar = false;
for(char c : lookIn) {
if(doesContainChar = c == lookFor)
break;
}
return doesContainChar;
}
答案 1 :(得分:0)
您可能希望使用for
循环来迭代每个单词的字母,直到找到元音。例如:
String wordCap = word.toUpperCase();
char vowels;
for (int i=0; i<wordCap.length(); i++) {
if (isVowel(wordCap.charAt(i))) {
vowels = wordCap.charAt(i);
break;
}
}
当然,为了保持示例的简洁,我只使用了isVowel()
。你必须像在第一个if
语句中那样将它识别为元音(或者自己编写isVowel()
方法)。
要修改单词,您还需要声明一个变量来保存元音的索引。可以为此添加上一部分代码,如下所示:
String wordCap = word.toUpperCase();
char vowels;
int vowelIndex;
String newWord;
for (int i=0; i<wordCap.length(); i++) {
if (isVowel(wordCap.charAt(i))) {
vowels = wordCap.charAt(i);
vowelIndex = i;
break;
}
}
然后,您可以在修改单词时引用vowelIndex
。
if (vowelIndex == 0) {
newWord = word + "way";
} else {
newWord = word.substring(vowelIndex) + word.substring(0, vowelIndex) + "ay";
}
return word;
