Java – Display time in 12 hour format with AM/PM using SimpleDateFormat

In this tutorial we will see how to display time in 12 hour format with AM/PM using the SimpleDateFormat.

1. Display current date and time in 12 hour format with AM/PM

There are two patterns that we can use in SimpleDateFormat to display time. Pattern “hh:mm aa” and “HH:mm aa”, here HH is used for 24 hour format without AM/PM and the hh is used for 12 hour format with AM/PM.
hh – hours in 12 hour format
mm – minutes
aa – AM/PM marker.
In this example we are displaying current date and time with AM/PM marker.

import java.text.SimpleDateFormat;
import java.text.DateFormat;
import java.util.Date;
class Example
{
    public static void main(String[] args)
    {	
    	//Displaying current time in 12 hour format with AM/PM
    	DateFormat dateFormat = new SimpleDateFormat("hh.mm aa");
    	String dateString = dateFormat.format(new Date()).toString();
    	System.out.println("Current time in AM/PM: "+dateString);
    	
    	//Displaying current date and time in 12 hour format with AM/PM
    	DateFormat dateFormat2 = new SimpleDateFormat("dd/MM/yyyy hh.mm aa");
    	String dateString2 = dateFormat2.format(new Date()).toString();
    	System.out.println("Current date and time in AM/PM: "+dateString2);
    }
}

Output:

Current time in AM/PM: 12.30 PM
Current date and time in AM/PM: 20/10/2017 12.30 PM

2. Displaying given date and time with AM/PM

In the above example, we are showing the current date and time with AM/PM. In this example we are displaying the given date and time with AM/PM.

import java.text.SimpleDateFormat;
import java.util.Date;
import java.text.ParseException;
class Example
{
    public static void main(String[] args)
    {	
    	
    	//Displaying given time in 12 hour format with AM/PM
    	String dateString3 = "22.30"; 
    	//old format
    	SimpleDateFormat sdf = new SimpleDateFormat("HH.mm");
    	try{
    	Date date3 = sdf.parse(dateString3);
    	//new format
    	SimpleDateFormat sdf2 = new SimpleDateFormat("hh.mm aa");
    	//formatting the given time to new format with AM/PM
    	System.out.println("Given time in AM/PM: "+sdf2.format(date3));
    	}catch(ParseException e){
    		e.printStackTrace();
    	}
    	
    	//Displaying given time in 12 hour format with AM/PM
    	String dateString4 = "21/12/2016 21.20"; 
    	//old format
    	SimpleDateFormat sdf3 = new SimpleDateFormat("dd/MM/yyyy HH.mm");
    	try{
    	Date date4 = sdf3.parse(dateString4);
    	//new format
    	SimpleDateFormat sdf4 = new SimpleDateFormat("dd/MM/yyyy hh.mm aa");
    	//formatting the given time to new format with AM/PM
    	System.out.println("Given date and time in AM/PM: "+sdf4.format(date4));
    	}catch(ParseException e){
    		e.printStackTrace();
    	}
    }
}

Output:

Given time in AM/PM: 10.30 PM
Given date and time in AM/PM: 21/12/2016 09.20 PM
