           {       
                cities[i] = cities[i].toUpperCase();  
                for(int j=i+1; j<cities.length; j++)  
                {  
                     cities[j] = cities[j].toUpperCase();  
                     if(cities[i].compareTo(cities[j]) > 0)  
                     {  
                          String temp= new String();  
                          temp = cities[i];  
                          cities[i] = cities[j];  
                          cities[j] = temp;  
                     }  
                }  
                System.out.println(cities[i]);
