Responsive Design: Include @media queries as mixins using LESS

I have to includ the @media queries as a seperate file and sections before.
That was very circumstantial and took a long time to find and redefine each elemnt to display properly on Mobile Devices.

Since LESS has included the support of mixins, it is very comfortable to define such queries.

All you need is:

1. Define your preferred Breakpoints as Variables 
2. Include the queries inside the main element 

Sample:


Step 1: Define your preferred Breakpoints as Variables

	@extraSmall: ~"only screen and (max-width: 360px)";
	@small: ~"only screen and (max-width: 640px)";
	@medium: ~"only screen and (max-width: 768px)";
	@large: ~"only screen and (max-width: 960px)";

Step 2: Include the queries inside the main element

	.menuWrapper {
	position: relative;
	width: 100%;
	& .menu {
	display: table;
	margin: auto;
	width: 70%;
	@media @medium {
	width: 90%;
	}
	@media @extraSmall {
	width: 95%;
	}
	}
	}

nice HTML HR (horizontal rule) with CSS

here is a sample of creating a horizontal rule with only CSS commands without using an Image. The point here is to define a DIV element with same settings as HR and rotate and put it over the HR.

Schedule a Method to run later

If you do not want to run a method in the normal application process flow, you can use ScheduledExecutorService to run it later. This sample code executes the "myFunction" 5 Seconds later.

	final ScheduledExecutorService exec = Executors.newScheduledThreadPool(1);
	exec.schedule(new Runnable() {
	@Override
	public void run() {
	System.out.println("=================> Running");
	myFunction();
	}
	}, 5, TimeUnit.SECONDS);

JAXB : IllegalAnnotationExceptions - Class has two properties of the same name

just developing a test jaxb application and wanted to let getters and setters be created automatically with Lombok.
As I was attempting to assign annotations of private field members, got this exception:


Exception in thread "main" com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Class has two properties of the same name "name"
this problem is related to the following location:
at public java.lang.String de.domain.jaxbtest.model.Book.getName()
at de.domain.jaxbtest.model.Book
at private java.util.List de.domain.jaxbtest.model.Bookstore.bookList
at de.domain.jaxbtest.model.Bookstore

the solution was easy as just adding @XmlAccessorType(XmlAccessType.FIELD) to defined class:

	@Data
	@XmlRootElement(name = "book")
	@XmlAccessorType(XmlAccessType.FIELD)
	public class Book {
	@XmlElement(name = "title")
	private String name;
	private String author;
	private String publisher;
	private String isbn;
	}
