publicclass Job03 {
    publicstaticvoid main(String[] args) {
        Scanner input = new Scanner(System.in);
       
        StringBuilder upperCaseSb = new StringBuilder();

        for(int i=0;i<result.length();i++){
         //int chr = (int)result.charAt(i);
         /*char chr = result.charAt(i);
         if (chr>=97 && chr<=122){
            lowerCaseSb.append(chr);
    
            upperCaseSb.append(chr);
    
          char chr = result.charAt(i);
          if ( Character.isUpperCase(chr)){
    
          }else{
    
    
       
        System.out.println("大写字母："+upperCaseSb.toString());
