- equals(Object obj) : java.text.SimpleDateFormat.equals(Object obj) compares two SimpleDateFormat objects
Syntax : public boolean equals(Object obj) Parameters : obj : object to compare with Return : true, if equal ; else false
Java
// Java Program illustrating// use of SimpleDateFormat.equals() methodimport java.text.*;import java.util.Calendar; public class NewClass{ public static void main(String[] args) throws InterruptedException, ParseException { // Setting formatter SimpleDateFormat geek = new SimpleDateFormat(); geek.applyPattern("MMM"); // Use of equals() : System.out.println("Is equal ? : " + geek.equals(new SimpleDateFormat())); }} |
Output :
Is equal ? : false
- setDateFormatSymbols(DateFormatSymbols newSymbols) : java.text.SimpleDateFormat.setDateFormatSymbols(DateFormatSymbols newSymbols) sets date and time format symbols of the required date format.
Syntax : public void setDateFormatSymbols(DateFormatSymbols newSymbols) Parameters : newSymbols : new format symbols for data and time Return : -------
Java
// Java Program illustrating// use of DateFormatSymbols() methodimport java.text.*;import java.util.*;public class NewClass{ public static void main(String[] args) throws InterruptedException, ParseException { DateFormatSymbols format_symb = new DateFormatSymbols(new Locale("en", "US")); String[] days = format_symb.getShortWeekdays(); int j = 1; for (int i = 1; i < days.length; i++) { System.out.print("Day" + j++ + " : " + days[i] + "\n"); } }} |
Output :
Day1 : Sun Day2 : Mon Day3 : Tue Day4 : Wed Day5 : Thu Day6 : Fri Day7 : Sat

Output :
java.text.DateFormatSymbols@f86e64e0 Date : 6/24/17 12:49 PM
- applyLocalizedPattern(String str) : java.text.SimpleDateFormat.applyLocalizedPattern(String str) applies the given localized string pattern to date format.
Syntax : public void applyLocalizedPattern(String str) Parameters : str : string pattern set to new date and time format Return : -------
Java
// Java Program illustrating// use of applyLocalizedPattern() method import java.text.*;import java.util.Calendar; public class NewClass{ public static void main(String[] args) throws InterruptedException { SimpleDateFormat geek = new SimpleDateFormat(); // Initializing calendar Object Calendar c = Calendar.getInstance(); // Using 'arg' pattern String arg = "MM / dd / yy HH:mm Z"; // Use of applyLocalizedPattern() geek.applyLocalizedPattern(arg); System.out.println("Use of applyLocalizedPattern() : "+geek.toLocalizedPattern()); }} |
Output :
Use of applyLocalizedPattern() : MM / dd / yy HH:mm Z
