java.time.LocalTime Class in Java

The LocalTime class, available in the java.time package, represents a time without date and timezone. Introduced in Java 8, it is part of the modern Date-Time API and is used to store and manipulate time values such as meeting schedules, alarms, business hours, and event timings.

• Represents only hour, minute, second, and nanosecond.
• Provides methods for formatting, parsing, and comparing time values.
• Immutable and thread-safe.

Declaration Of java.time.LocalTime Class

public final class LocalTime
extends Object
implements Temporal, TemporalAdjuster,
Comparable<LocalTime>, Serializable

Approach

1. Import the java.time.LocalTime class.
2. Create a LocalTime object using methods such as now(), of(), or parse().
3. Perform operations like formatting, comparison, addition, or subtraction.
4. Display the result using System.out.println().

Example: Program to illustrate LocalTime Class

// Importing LocalDateTime class from
// java.time package
import java.time.LocalTime;

// Main Class
public class GFG {

    // Main driver method
    public static void main(String args[])
    {

        // Creating an object of LocalTime class by
        // declaring a variable to store LocalTime
        LocalTime ltime = LocalTime.now();

        // Print and display the LocalTime value
        System.out.println("Local time value : " + ltime);
    }
}

Local time value : 06:20:52.986897

Explanation: The LocalTime.now() method returns the current system time. The program creates a LocalTime object and prints the current time, including hours, minutes, seconds, and nanoseconds.

Example: Program to illustrate LocalTime where plusMethod() is illustrated

// Importing LocalTime class from
// java.time package
import java.time.LocalTime;

// Main Class
public class GFG {

    // main driver method
    public static void main(String args[])
    {
        // Creating an object of LocalTime Class by
        // declaring a variable to store LocalTime
        LocalTime ltime = LocalTime.now();

        // Now plusMinute() will add up minutes to the
        // LocalTime
        LocalTime time3 = ltime.plusMinutes(120);

        // Display the time using object of class
        System.out.println("Time : " + time3);
    }
}

Time : 08:34:59.135137

Explanation: The plusMinutes(120) method adds 120 minutes (2 hours) to the current time and returns a new LocalTime object. The original time remains unchanged because LocalTime is immutable.

Advantages of LocalTime

The LocalTime class provides a simple and reliable way to work with time without including date or time zone information.

• Provides methods for performing time-based calculations and comparisons.
• Creates new LocalTime objects instead of modifying existing instances, ensuring immutability.
• Supports different time formats using DateTimeFormatter.
• Useful for applications that require time handling without date or time zone information.
