java - 使用java中的子字符串从字符串中删除元音

Question

 public class Vowels {
    public static void main(String[] args) {
        char []a={'a','e','i','o','u','e'};
        String line="abcee";
        for (char c : a) {
            for (int i = 0; i < a.length; i++) {
                if (line.charAt(i)==c) {
                    line=line.substring(0, i)+line.substring(i+1);
                }
            }
        }
        System.out.println(line);
    }
}

这段代码有什么问题，不仅仅是没有删除相同的元音。

Answer 1

此代码将从任何字符串中删除A E I O和U。此代码来自 Writing a method to remove vowels in a Java String ，有关使用循环的解决方案，请参阅 Remove all vowels in a string with Java .

public static void main(String[] args) {
    String line = "abcee";
    
    line = line.replaceAll("[AEIOUaeiou]", "");
    
    String alphabet = "abcdefghijklmnopqrstuvwxyz";
    
    alphabet = alphabet.replaceAll("[AEIOUaeiou]", "");
    
    System.out.println(line);
    
    System.out.println(alphabet);
}

输出:

bc

bcdfghjklmnpqrstvwxyz
