如何使用Java在给定的字符串中找到元音？
您可以使用charAt()方法读取字符串中的字符。要在给定的字符串中找到元音，您需要将其中的每个字符与元音字母进行比较。
示例
public class FindingVowels { public static void main(String args[]) { String str = new String("Hi Welcome to Nhooo"); for(int i=0; i<str.length(); i++) { if(str.charAt(i) == 'a'|| str.charAt(i) == 'e'|| str.charAt(i) == 'i' || str.charAt(i) == 'o' || str.charAt(i) == 'u') { System.out.println("Given string contains "+str.charAt(i)+" at the index "+i); } } }}输出结果
Given string contains i at the index 1 Given string contains e at the index 4 Given string contains o at the index 7 Given string contains e at the index 9 Given string contains o at the index 12 Given string contains u at the index 15 Given string contains o at the index 17 Given string contains i at the index 19 Given string contains a at the index 20 Given string contains o at the index 24 Given string contains i at the index 25
