The FILTER_SANITIZE_STRING constant deletes tags and encodes special characters from a string.FlagsFILTER_FLAG_NO_ENCODE_QUOTES − Do not encode quotesFILTER_FLAG_STRIP_LOW − Removes characters with ASCII value less than 32FILTER_FLAG_STRIP_HIGH − Removes characters with ASCII value greater than 127FILTER_FLAG_ENCODE_LOW − Encodes characters with ASCII value less than 32FILTER_FLAG_ENCODE_HIGH − Encodes characters with ASCII value greater than 127FILTER_FLAG_ENCODE_AMP − Encodes the "&" character to &ReturnThe FILTER_SANITIZE_STRING constant does not return anything.Example Live DemoOutputThe following is the output.Demo!
For using Calendar class, import the following package.import java.util.Calendar;Using the Calendar class, create an object.Calendar calendar = Calendar.getInstance();Now, create a string array of the month names.String[] month = new String[] {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };Display the month name.month[calendar.get(Calendar.MONTH)]The following is an example.Example Live Demoimport java.util.Calendar; public class Demo { public static void main(String[] args) { Calendar calendar = Calendar.getInstance(); String[] month = new String[] {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" }; System.out.println("Current Month = " + month[calendar.get(Calendar.MONTH)]); ...
