我不知道为什么,但在这个方法中,第 5 个和第 10 个元素每次都会被大写。 我找不到原因。 例如:传递“ZpglnRxqenU”作为参数应返回:“Z-Pp-Ggg-Llll-Nnnnn-Rrrrrrr-Xxxxxxx-Qqqqqqqq-Eeeeeeeee-Nnnnnnnnnnn-Uuuuuuuuuuu”,但返回:“Z-Pp-Ggg-Llll-Nnnnn -RRRRRR-Xxxxxxx-Qqqqqqq-Eeeeeeeee-Nnnnnnnnnn-UUUUUUUUUUU”
请注意,与其他字符不同,R 和 U 均为大写。

/*
this is upperCasing every 5th and 10th character for some reason
*/
// TODO: 26/12/2019 stop upperCasing 5th and 10th element.
finalString += strArr[i].toUpperCase();

return finalString;
最佳答案
你必须首先添加这一行: 字符串 = string.toLowerCase();
公共(public)字符串构建器(字符串字符串){
string = string.toLowerCase();
/*
Here we split the string we receive by characters and save these characters in
a new array called strArr.
*/
String[] strArr = string.split("");
String finalString = "";
/*
We iterate through the array of characters adding "-" each time we start to
represent a new character.
We add the characters N times where N is the order of appearance in the string
we receive as param.
*/
for (int i = 0; i < strArr.length; i++) {
if(i > 0){
finalString += "-";
}
for (int j = 0; j < i + 1; j++) {
if(j == 0){
/*
this is upperCasing every 5th and 10th character for some reason
*/
// TODO: 26/12/2019 stop upperCasing 5th and 10th element.
finalString += strArr[i].toUpperCase();
continue;
}
finalString += strArr[i];
}
}
return finalString;
}
关于java - 我在 for 循环中大写了太多元素,但仅在特定索引上大写,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59493830/
