Class Loading while running JVM

  • The Order is
    • Bootstrap classes - Classes that comprise the Java platform, including the classes in rt.jar and several other important jar files.
    • Extension classes - Classes that use the Java Extension mechanism. These are bundled as .jar files located in the extensions directory.
    • User classes - Classes defined by developers and third parties that do not take advantage of the extension mechanism. You identify the location of these classes using the -classpath option on the command line (the preferred method) or by using the CLASSPATH environment variable.

Primitive Obsession with Example

Primitive Obsession is the name of a code smell that occurs when we use primitive data types to represent domain ideas. For example, we use a string to represent a message or an integer to represent an amount of money. For Example: Code with Primitive Obsession // primitiveObsession.java public class primitiveObsession { public static void main ( String args []) { Integer [] cityPopulations = { 13000000 , // London 21903623 , // New York 12570000 , // Tokyo 1932763 , // Stockholm 1605602 , // Barcelona 4119190 // Sydney }; for ( Integer cityPopulation : cityPopulations ) { System . out . println ( cityPopulation ); } } } public class City { private final String name ; private final int population ; private final Continent continent ; public String getName () { return name ; } public int getPopulation () { return population ; } public Continent ge...

Factory Pattern

This pattern is used when it must be decided at run time which one of several compatible classes is to be instantiated. For example, the abstract Collator class's getInstance() method returns a collation object that is appropriate for the default locale, as determined by java.util.Locale.getDefault() : Like other locale-sensitive classes, you can use the static factory method, getInstance, to obtain the appropriate Collator object for a given locale.  The following example shows how to compare two strings using the Collator for the default locale. Compare two strings in the default locale Collator myCollator = Collator.getInstance(); if( myCollator.compare("abc", "ABC") < 0 ) System.out.println("abc is less than ABC"); else System.out.println("abc is greater than or equal to ABC");

Create AEM Project using Maven Archetype 11

Let's start with our journey of Adobe Experience Manager project development. I am using AEM 6.3, Java 1.8 and Maven 3.2 . Follow below steps and try to replicate the same at your end. Let know of any issues if you face in the comment section. Go to your project path and validate the commands mvn -v and java -version are pointing to the accurate installation of Maven and JDK. Type below command to start: "mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeGroupId=com.adobe.granite.archetypes -DarchetypeArtifactId=aem-project-archetype -DarchetypeVersion=11 -DarchetypeCatalog=https://repo.adobe.com/nexus/content/groups/public/" Once this is done downloading the dependency and starts creating folder structure, it will ask you for the required information. You can refer below information that I have given, you need to use yours based on your requirement or client need.  Define value for property 'groupId': : first-project-aem De...
