Can someone tell me why this isn't working..?

static int calcLex(String A){
    int res=0;
    for(int i=0; i<A.length();i++){
        res += (int)A.charAt(i);   
    }
    return res;
}

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());

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

    } else {
        System.out.println("No");
    }

    A=A.toLowerCase();
    B=B.toLowerCase();

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

}
