错误“找不到符号方法charAt（int）”？

Question

System.out.println("Enter a sentence to get it translated into Pig Latin: ");

String sentence=kb.nextLine();

String[] words = sentence.split(" ");

char a=words.charAt(0);

Answer 1

words是一个数组，charAt()方法是为String定义的。所以你想使用：

words[index].charAt(0)

相反，index是数组中String的位置。

Answer 2

单词是一个字符串数组。尝试使用单词[index]。分割后，子字符串将存储如下 -

Enter = words[0]
a = words[1]
sentence = words[2]
to = words[3]
get = words[4]
it = words[5]
translated = words[6]
into = words[7]
Pig = words[8]
Latin: = words[9]

访问单词[index] .chartAt（0）将返回相应子字符串的第一个字符。
