Lazy me

Scanner sc=new Scanner(System.in);
String A=sc.next();
String B=sc.next();
System.out.println(A.length()+B.length());
System.out.println(A.compareTo(B)>0?"Yes":"No");
System.out.println(A.substring(0, 1).toUpperCase()+A.substring(1, A.length())+" "+B.substring(0, 1).toUpperCase()+B.substring(1, B.length()))

By the general rules for writing "Clean Code" (according to the book), we should write functions as small as possible. Putting the 'capitalize' part in another function should be a better practice.

 public static void main(String[] args) {
        
        Scanner sc=new Scanner(System.in);
        String A=sc.next();
        String B=sc.next();
        System.out.println(A.length()+B.length());
        System.out.println(A.compareTo(B)>0?"Yes":"No");
        System.out.println(capitalizeFirstLetter(A) + " " + capitalizeFirstLetter(B));
    }
    
    public static String capitalizeFirstLetter(String original) {
    if (original == null || original.length() == 0) {
        return original;
    }
    return original.substring(0, 1).toUpperCase() + original.substring(1);
}

Here is my code. This is Java Solution.

All TestCase is Passed.

GoodLuck ~!

    System.out.println(A.length() + B.length());

    if(A.compareTo(B) > 0){
        System.out.println("Yes");
    } else {
        System.out.println("No");
    }

    A = (A.substring(0,1)).toUpperCase() + A.substring(1);       
    B = (B.substring(0,1)).toUpperCase() + B.substring(1);
    System.out.println(A + " " + B);

My answer, passed every test cases

public class Solution {
    public static void main(String[] args) {        
        Scanner sc=new Scanner(System.in);
        String A=sc.next();
        String B=sc.next();
        System.out.print(A.length()+B.length()+"\n"+(A.compareTo(B)>0 ? "Yes" : "No")+"\n"+uC(A)+" "+uC(B));}
    private static String uC(String str){
        char[] ch = str.toCharArray();
        if(ch[0] >= 'a' && ch[0] <= 'z')ch[0]-=32;
        return String.valueOf(ch);
    }
}

So much simpler to do with C++... why aren't strings seen as arrays of characters? Why can't you just do "A > B"?
