Get Current Date and Time in Java

There are many ways to get current the date and time in Java. There are many classes that can be used to get current date and time in Java.

java.time.format.DateTimeFormatter class
java.text.SimpleDateFormat class
java.time.LocalDate class
java.time.LocalTime class
java.time.LocalDateTime class
java.time.Clock class
java.util.Date class
java.sql.Date class
java.util.Calendar class

Get Current Date and Time: java.time.format.DateTimeFormatter

The LocalDateTime.now() method returns the instance of LocalDateTime class. If we print the instance of LocalDateTime class, it prints the current date and time. To format the current date, you can use DateTimeFormatter class which is included in JDK 1.8.

FileName: CurrentDateTimeExample1.java

import java.time.format.DateTimeFormatter;
import java.time.LocalDateTime;  
public class CurrentDateTimeExample1 {  
  public static void main(String[] args) {  
   DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");
   LocalDateTime now = LocalDateTime.now();
   System.out.println(dtf.format(now));
  }  
}  

Test it Now

Output:

2017/11/06 12:11:58

Get Current Date and Time: java.text.SimpleDateFormat

The SimpleDateFormat class is also used for formatting date and time. But it is old approach.

FileName: CurrentDateTimeExample2.java

import java.text.SimpleDateFormat;
import java.util.Date;
public class CurrentDateTimeExample2 {
public static void main(String[] args) {
	SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
	Date date = new Date();
	System.out.println(formatter.format(date));
}
}

Test it Now

Output:

06/11/2017 12:26:18

Get Current Date: java.time.LocalDate

The LocalDate.now() method returns the instance of the LocalDate class. If we print the instance of the LocalDate class, it prints the current date.

FileName: CurrentDateTimeExample3.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample3 
{    
  // main method
  public static void main(String[] argvs) 
  {    
        System.out.println(java.time.LocalDate.now());  
  }    
}

Output:

2021-12-17

Get Current Time: java.time.LocalTime

The LocalTime.now() method returns the instance of LocalTime class. If we print the instance of LocalTime class, it prints the current time.

FileName: CurrentDateTimeExample4.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample4 
{    
  // main method
  public static void main(String[] argvs) 
  {    
        System.out.println(java.time.LocalTime.now());  
  }    
}

Output:

15:55:10.424178667

Get Current Date & Time: java.time.LocalDateTime

The LocalDateTime.now() method returns the instance of LocalDateTime class. If we print the instance of LocalDateTime class, it prints the current date and time.

FileName: CurrentDateTimeExample5.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample5 
{    
  // main method
  public static void main(String[] argvs) 
  {    
        System.out.println(java.time.LocalDateTime.now());  
  }    
}

Output:

2021-12-17T15:59:19.516010365

Get Current Date & Time: java.time.Clock

The Clock.systemUTC().instant() method returns the current date and time both.

FileName: CurrentDateTimeExample6.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample6 
{    
  // main method
  public static void main(String[] argvs) 
  {    
    System.out.println(java.time.Clock.systemUTC().instant());  
  }    
}

Output:

2021-12-17T16:04:03.930224479Z

Get Current Date & Time: java.util.Date

By printing the instance of java.util.Date class, you can print the current date and time in Java. There are two ways to do so.

1st way:

FileName: CurrentDateTimeExample7.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample7 
{    
  // main method
  public static void main(String[] argvs) 
  {    
    // creating a new object of the class Date
    java.util.Date date = new java.util.Date();  
    System.out.println(date); 
     
  }    
}

Output:

Fri Dec 17 16:07:15 GMT 2021

2nd way:

FileName: CurrentDateTimeExample8.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample8 
{    
  // main method
  public static void main(String[] argvs) 
  { 
    long millis = System.currentTimeMillis();
    
    // creating a new object of the class Date
    java.util.Date date = new java.util.Date(millis);    
    System.out.println(date); 
      
     
  }    
}

Output:

Fri Dec 17 16:07:15 GMT 2021

Get Current Date: java.sql.Date

By printing the instance of java.sql.Date class, you can print current date in Java. It doesn't print time. This date instance is generally used to save the current date in the database.

FileName: CurrentDateTimeExample9.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample9 
{    
  // main method
  public static void main(String[] argvs) 
  { 
    long millis=System.currentTimeMillis();
    
    // creating a new object of the class Date
    java.sql.Date date = new java.sql.Date(millis);     
    System.out.println(date); 
      
     
  }    
}

Output:

2021-12-17

Get Current Date & Time: java.util.Calendar

The Calendar class can be used to get the instance of the Date class. The getTime() method of the Calendar class returns the instance of java.util.Date. The Calendar.getInstance() method returns the instance of the Calendar class.

FileName: CurrentDateTimeExample10.java

// important import statements
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
  
public class CurrentDateTimeExample10 
{    
  // main method
  public static void main(String[] argvs) 
  { 
    long millis=System.currentTimeMillis();
    
    // creating a new object of the class Date
    java.sql.Date date = new java.sql.Date(millis);     
    System.out.println(date); 
      
     
  }    
}

Output:

Fri Dec 17 19:23:10 GMT 2021

Note: It is recommended to use the Calendar class for getting the current date and time in classical Date API. Since Java 8, you can use LocalDate, LocalTime, or LocalDateTime classes.
