How to print a Letter between two vowels using java

I Have a String S= "I love bangalore " It should print the letters between 2 vowels like below : 1.v 2.ng 3.l 4.r

Note : I am able to print if there only 1 letter b/w 2 vowels not more than that.

This what I have tried : 

String a = "i love bangalore";

String[] words = a.split(" ");
for (String word : words) {
    for (int i = 1; i < word.length(); i++) {
        if (word.length() > 3) {
          if(i==word.length()-1){
              System.out.println("skip");
          }
          else if(checkIsVowel(word.charAt(i))&&!checkIsVowel(word.charAt(i+1))&&checkIsVowel(word.charAt(i+2))){
              System.out.println(word.charAt(i+1));
              }

          }
        }
    }

The best way to do this is as follows:

  1. Find a vowel, non-vowel pair.
  2. Set result to non-vowel.
  3. Continue to find non-vowels, appending to result
  4. When a vowel is encountered, either print or save result
  5. remembering you are at a vowel, go back to 1 and repeat until word is exhausted.

Make certain you use print statements to help debug your program.

The way you are trying is not right because

  1. You are checking for length 3 or more which is not true
  2. You are checking for vowel, normal alphabet, vowel which is also not true. ex: angl

Here is one way to solve it

String[] words = str.split(" ");
for (String word : words) {
    int firstVowelIndex = -1;
    for (int i = 0; i < word.length(); i++) {
        char ch = word.charAt(i);
        if (checkIsVowel(ch)) {
            // if vowel index is found again and there exists at least one character between the two vowels
            if (firstVowelIndex != -1 && i - firstVowelIndex != 0) {
                System.out.println(word.substring(firstVowelIndex + 1, i));
            }
            // vowel index is assigned
            firstVowelIndex = i;
        }
    }
}

Input:

i love bangalore

Output:

v
ng
l
r
