LocalDateTime withMinute() method in Java with Examples

The withMinute() method of LocalDateTime class in Java is used to get a copy of this LocalDateTime with the minutes changed to the minutes passed as the parameter to this method. The remaining values of this LocalDateTime remains the same.

Syntax:

public LocalDateTime withMinute(int minutes)

Parameter: This method accepts a single mandatory parameter minutes which specifies the minutes to be set in the resultant LocalDateTime instance. The value of this minutes can range from 0 to 59.

Returns: The function returns a LocalDateTime instance with the minutes changed to the minutes passed as the parameter to this method. The remaining values of this LocalDateTime remains the same.

Exceptions: The function throws a DateTimeException if the minutes value is invalid.

Below programs illustrate the LocalDateTime.withMinute() method:

Program 1:

// Program to illustrate the withMinute() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Get the LocalDateTime instance
        LocalDateTime dt = LocalDateTime.now();

        // Get the String representation of this LocalDateTime
        System.out.println("Original LocalDateTime: "
                           + dt.toString());

        // Get a new LocalDateTime with minutes 0
        System.out.println("New LocalDateTime: "
                           + dt.withMinute(0));
    }
}

Output:

Original LocalDateTime: 2018-11-30T12:52:26.105
New LocalDateTime: 2018-11-30T12:00:26.105

Program 2:

// Program to illustrate the withMinute() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Get the LocalDateTime instance
        LocalDateTime dt
            = LocalDateTime
                  .parse("2015-04-06T10:15:30");

        // Get the String representation of this LocalDateTime
        System.out.println("Original LocalDateTime: "
                           + dt.toString());

        // Get a new LocalDateTime with minutes 59
        System.out.println("New LocalDateTime: "
                           + dt.withMinute(59));
    }
}

Output:

Original LocalDateTime: 2015-04-06T10:15:30
New LocalDateTime: 2015-04-06T10:59:30
