如何显示元音而不是只计算元音（元音）？

Question

下面是计算元音的代码。如何显示元音而不是只计算它们？

System.out.println("Enter the String:"); 

String text = we.readLine(); 

int count = 0; 
for (int i = 0; i < text.length(); i++) { 
    char c = text.charAt(i); 
    if (c=='a' || c=='e' || c=='i' || c=='o' || c=='u') { 
     count++; 
    } 
} 
System.out.println("The number of vowels in the given String are: " + count);

对于备用，可以创建元音的字符数组，转动String转换为字符数组，并比较每个索引：

char[] vowels = {'a', 'e', 'i', 'o', 'u'}; 
String text = "Programming"; 

for (char c : text.toCharArray()) { 
    for (char vowel : vowels) { 
     if (c == vowel) { 
      System.out.println(text + " contains the vowel: " + vowel); 
     } 
    } 
}
