How to get substring that start and end with the same character in Java

Answer 1

public class MyClass {
    static int start = 0, end = 0;
     
    public static void char_substr(String str, char ch) {  
        int len =  str.length();
        for (int i = 0; i < len; i++) {  
            if (str.charAt(i) == ch) {
                start = i;
                for (int j = i + 1; j < len; j++) {
                    if (str.charAt(j) == ch) {  
                        end = j + 1; 
                        break;
                    }
                }
            }
            if (start != 0)
                break;
        }
    }  
 
    public static void main(String args[]) {
        String str = "hgdabcvauyec"; 

        char_substr(str, 'a');

        System.out.println(str.substring(start, end));
    }
}
