Array-Java(find vowelString)

[umbral flax]

Would you willing to help me to solve the problem in Java(Pic1+Pic2 are the questions and some hints):i feel hard to get the each word in string to compare with the VowelStrings since each String is in a array. Thank you so much if anyone could teach me.

public class Concrete2 {
    private static boolean bool=true;
    private static int countNum=0;
    private static final String[] STR_ARR={"are","amy","u"};
    private static final int LEFT=0;
    private static final int RIGHT=2;
    public static void main(String[] args) {
        Concrete2 concrete2=new Concrete2();
        int answer=concrete2.vowelStrings();
        System.out.println(answer);
    }

    int vowelStrings(){
        class CheckIfVowel{
            int count=0;
            private boolean passString(String string){
                count=0;
                checkString(string,'a');
                checkString(string,'e');
                checkString(string,'i');
                checkString(string,'o');
                checkString(string,'u');
                return count==2;
            }
            private void checkString(String string,char vowel){
                if (string.charAt(0)==vowel){
                     count++;
                }
                if (string.charAt(string.length()-1)==vowel){
                    count++;
                }
            }

        }
        CheckIfVowel checkIfVowel=new CheckIfVowel();
        for (int i=LEFT;i<=RIGHT;i++){
             bool=checkIfVowel.passString(STR_ARR[i]);
            if (bool) countNum++;
        }
        return countNum;
    }
}``` test this code through different cases it's not the best

tell me if it's not showing expected output

I'll give you some pseudocode maybe that'll help.

public int vowelStrings(String[] words, int left, int right) {
    count = 0
    while left is smaller or equal to right:
        word = words[left]
        if the first character and the last character of the word are both vowels:
          increase count by 1
    return count
}

and here is the pseudocode of a method you could use to determine whether a character is a vowel or not

public boolean isVowel(char character){
  character = Convert character to lower case
  return true if character is a vowel, false otherwise
}
