Java 8 LocalTime example.


LocalTime class is a time without a time-zone in the ISO-8601 calendar system, such as 10:15:30.

LocalTime is an immutable date-time object that represents a time, often viewed as hour-minute-second. Time is represented to nanosecond precision.

This class does not store or represent a date or time-zone. Instead, it is a description of the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of LocalTime may have unpredictable results and should be avoided. The equals method should be used for comparisons.

LocalTime class is immutable and thread-safe.

LocalTimeEx
package com.java2novice.datetime;

import java.time.LocalTime;

public class LocalTimeEx {

	public static void main(String[] args) {

		// get current time
		LocalTime currTime = LocalTime.now();
		System.out.println("current time: "+currTime);

		// create time object with values
		LocalTime givenTime = LocalTime.of(2, 30);
		System.out.println("early morning time: "+givenTime);

		// time with seconds
		LocalTime timeWithSec = LocalTime.of(2, 30, 28);
		System.out.println("early morning time with seconds: "+timeWithSec);

		// post lunch time
		LocalTime postLunch = LocalTime.of(15, 30, 28);
		System.out.println("post lunch time with seconds: "+postLunch);

		// converts no of seconds of the day to time
		LocalTime secOfDay = LocalTime.ofSecondOfDay(10160);
		System.out.println("seconds of the day: "+secOfDay);
	}
}

Output:
current time: 15:39:57.860
early morning time: 02:30
early morning time with seconds: 02:30:28
post lunch time with seconds: 15:30:28
seconds of the day: 02:49:20

Class, Constructor and Primitive data types
Class is a template for multiple objects with similar features and it is a blue print for objects. It defines a type of object according to the data the object can hold and the operations the object can perform. Constructor is a special kind of method that determines how an object is initialized when created. Primitive data types are 8 types and they are: byte, short, int, long, float, double, boolean, char.
