Java Program to Display Current Time in AM/PM Format

In the previous article, we have discussed about Java Program to Display Current Time

In this article we are going to see how to display current time in AM/PM using the SimpleDateFormat in Java along with suitable examples.

Java Program to Display Current Time in AM/PM Format

Explanation:

The java.text.SimpleDateFormat class provides inbuild methods to format the date and time in java.

There are 2 patterns which we can use in SimpleDateFormat to display the time.

“hh:mm:ss aa” , here hh is used for 12 hour format with AM/PM.
“HH:mm:ss aa”, here HH is used for 24 hour format without AM/PM.

Where,

hh: hours in 12 hour format
HH: hours in 24 hour format
mm: minutes
ss: Seconds
aa: AM/PM marker

Let’s see the program to understand it more clearly.

Java Program to Display Current Time in AM/PM Format by Using hh:mm aa Pattern
Java Program to Display Current Time in AM/PM Format by Using HH:mm:ss aa Pattern

Method-1: Java Program to Display Current Time in AM/PM Format by Using hh:mm aa Pattern

Approach:

Create an object of Date class which takes the system date and time.
Declare a string variable as ‘dateFormat’ and initialize it to “hh:mm:ss aa” pattern
Create an object of SimpleDateFormat as ‘s’ with the argument as ‘dateFormat’.
Print the result using method of SimpleDateFormat class as ‘s.format(date)’

Program:

import java.text.SimpleDateFormat;
import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create an object of Date class which takes the system date and time
        Date date = new Date();
        // Declare a string variable as ‘dateFormat’ and initialize it to "hh:mm:ss aa" pattern
      	String dateFormat = "hh:mm:ss aa";
        // Create an object of SimpleDateFormat as ‘s’ with the argument as ‘dateFormat’.
     	SimpleDateFormat s = new SimpleDateFormat(dateFormat);
        //Print the result using method of SimpleDateFormat class as ‘s.format(date)’
      	System.out.println("The current time in 12 hours format is: "+s.format(date));
    }
}

Output:

The current time in 12 hours format is: 06:23:50 AM

Method-2: Java Program to Display Current Time in AM/PM Format by Using HH:mm:ss aa Pattern

Approach:

Create an object of Date class which takes the system date and time
Declare a string variable as ‘dateFormat’ and initialize it to “HH:mm:ss aa” pattern
Create an object of SimpleDateFormat as ‘s’ with the argument as ‘dateFormat’.
Print the result using method of SimpleDateFormat class as ‘s.format(date)’

Program:

import java.text.SimpleDateFormat;
import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // Create an object of Date class which takes the system date and time
        Date date = new Date();
        // Declare a string variable as ‘dateFormat’ and initialize it to "hh:mm:ss aa" pattern
      	String dateFormat = "HH:mm:ss aa";
        // Create an object of SimpleDateFormat as ‘s’ with the argument as ‘dateFormat’.
     	SimpleDateFormat s = new SimpleDateFormat(dateFormat);
        //Print the result using method of SimpleDateFormat class as ‘s.format(date)’
      	System.out.println("The current time in 24 hours format is: "+s.format(date));
    }
}

Output:

The current time in 24 hours format is: 15:35:56 PM
