How to check if lowercase and uppercase characters in a string are in same order with Java

Answer 1

public class MyClass {
    public static boolean lowercase_uppercase_characters_same_order(String s) { 
         int len = s.length(); 
         String lower_s = "", upper_s = ""; 
       
         for (int i = 0; i < len; i++) { 
             if ((s.charAt(i)) >= 65 && s.charAt(i) <= 90) 
                 upper_s = upper_s + s.charAt(i); 
       
             if ((s.charAt(i)) >= 97 && s.charAt(i) <= 122) 
                 lower_s = lower_s + s.charAt(i); 
         } 
 
         return lower_s.toUpperCase().equals(upper_s); 
    } 
    public static void main(String args[]) {
        String s = "jaJvAVaA"; // javaJAVA
   
        if (lowercase_uppercase_characters_same_order(s)) 
            System.out.println("Yes"); 
        else
