//using trim method to trim the leading and trailling spaces of the string date
String date1= date.trim();
//using replace to remove , from the string
String date2=date1.replace(","," ");
//converting first character to uppercase and remaining into lowercase
String date3=date2.substring(0,1).toUpperCase() + date2.substring(1).toLowerCase();
