James Gosling initiated the Java language project in 1991. The first public implementation of Java was released as Java 1.0 in 1995. Oracle acquired Sun Microsystems in 2010. Java is an object-oriented programming language that is platform independent and promises "Write Once, Run Anywhere". A key component of Java is the Java Virtual Machine (JVM) which is responsible for memory allocation and provides a runtime environment for executing Java bytecode.
This document provides an overview of Spring MVC including:
- Spring MVC is a web framework built on the Servlet API that uses the MVC pattern. It features a DispatcherServlet that handles requests and delegates to controllers.
- The request processing workflow in Spring MVC involves the DispatcherServlet dispatching tasks to controllers, which interact with services and return a view name. The view is then rendered using a ViewResolver.
- Spring MVC applications use a WebApplicationContext containing web-related beans like controllers and mappings, which can override beans in the root context. Configuration can be done via XML or Java-based approaches. Important annotations map requests and bind parameters.

Creating GUI Component APIs in Angular and Web ComponentsRachael L Moore
So you’ve embraced architecting your Angular application with reusable components – cheers to you! But you have UI components that need to communicate with each other or expose public methods, and you’re wondering about your options. In this talk, we’ll cover how new web component standards, like Custom Elements, handle this. Next, we’ll walk through how to accomplish it today in Angular 1.x – and bring it all together into what a solution will look like in upcoming Angular 2. Afterwards, you'll know how to design and implement the public HTML and JavaScript interfaces of GUI components.

This document provides an overview of design patterns in Java. It defines design patterns as solutions to common programming problems that have proven successful in practice. The Gang of Four (GoF) published a seminal book on design patterns in 1994. Design patterns promote reusability and maintainability. There are three main categories of design patterns: creational, structural, and behavioral. Creational patterns deal with object creation mechanisms while structural patterns focus on relationships between entities. Behavioral patterns address communication between objects. Common examples like singleton, factory method, observer, and iterator patterns are described.

Test Driven Development:Unit Testing, Dependency Injection, Mockingmrjawright
Test Driven Development (TDD) is a software development process that involves writing unit tests before production code. Empirical studies have shown TDD can reduce defect density by 40-90% and increase productivity. Unit tests provide a safety net for changes by verifying new code does not break existing functionality. TDD promotes design principles like dependency injection and mocking to isolate code dependencies for flexible testing. While TDD may increase initial development time, it can save time during maintenance which accounts for 60-90% of a software lifecycle.

What is Dependency Injection ?
Dependency Inversion Principle
Types of Dependency Injection
Why DI ?
Understand DI with StudentSystem Example
DI with Spring Configuration
Benefits of DI
DI Using Annotations
Presenter: Pranav Kumar, Mindfire Solutions
3. DI: What it is ?
Dependency Injection is a software design pattern that allows removing hard
coded dependencies and making it possible to change them at run-time.
Dependencies are injected into objects by a container.
Also Known as Inversion Of Control (IoC).
Presenter: Pranav Kumar, Mindfire Solutions
4. DI Principle
The dependency inversion principle was postulated by Robert C. Martin
The principle states:
• Always use abstractions (Interface)
• Objects should define their dependencies only through
Constructor arguments
Arguments to a factory method.
Properties which are set on the object instance
Presenter: Pranav Kumar, Mindfire Solutions
5. DI: Types
Setter injection - Dependent module exposes a setter method that the framework uses to
inject the dependency.
Constructor injection - Dependencies are provided through the class constructor.
Presenter: Pranav Kumar, Mindfire Solutions
6. DI: Why ?
Dependency Injection enables 'POJO programming'
POJO programming facilitate
- Simplicity
- Effective separation of concerns
- Proper unit testing
Well-factored and well-tested code
- Tends to be well-designed code
- Evolves well into maintainable systems
Presenter: Pranav Kumar, Mindfire Solutions
7. Example: The Student System
To improve your skills in Java development, you decide to develop a student system.
You decide to use a file to store student information.
You create a class FileStudentDAO responsible for writing and reading to the file
You create a class StudentSystem responsible for performing the logic of the system.
You’ve learned that it’s a good thing to program to interfaces
Presenter: Pranav Kumar, Mindfire Solutions
10. Works! Or .. ?
The system is a big success – University of Oslo wants to adopt it!
Presenter: Pranav Kumar, Mindfire Solutions
11. Works! Or .. ?
You make a new implementation of the StudentDAO for University of Oslo, a
MySQLStudentDAO:
Presenter: Pranav Kumar, Mindfire Solutions
12. Works! Or .. ?
Won’t work! The FileStudentDAO is hard-coded into the StudentSystem:
The DefaultStudentSystem implementation is responsible for obtaining a StudentDAO.
Dependent both on the StudentDAO interface and the implementation
Presenter: Pranav Kumar, Mindfire Solutions
public class DefaultStudentSystem implements StudentSystem {
private StudentDAO studentDAO = new FileStudentDAO();
...
13. Problems: Student System
How to deploy the StudentSystem at different locations?
Develop various versions for each location?
• Time consuming
• Confusing and error-prone
• Requires more efforts for versioning
Solution:
Use Dependency Injection!
• More specific term derived from the term Inversion of Control
Presenter: Pranav Kumar, Mindfire Solutions
15. DI: With Spring
Bean: A class that is managed by a Spring IoC container
Setter based DI: Provide a public set-method for the dependency reference.
Presenter: Pranav Kumar, Mindfire Solutions
16. DI: Spring Configuration
Configuration: How to instantiate, configure, and assemble the objects in your application
• The Spring container accepts many configuration formats
• XML based configuration most common.
Presenter: Pranav Kumar, Mindfire Solutions
17. DI: Spring Configuration
Presenter: Pranav Kumar, Mindfire Solutions
studentDAO
Injected into
studentSystem
Refers to the
studentDAO
bean
Refers to the
studentDAO attribute in Java
class
20. DI: Benefits
Presenter: Pranav Kumar, Mindfire Solutions
Easier to swap implementations of dependencies
The system can be re-configured without changing the compiled code
Easier testing
Improved re-usability of your classes

21. DI: Using Annotations
Presenter: Pranav Kumar, Mindfire Solutions
Annotation is a meta-tag – applied to classes, methods...
• Associated with program behaviour
@Component
• Defines a class as a Spring container managed component
@Autowired
• Tells Spring to inject a component
Classpath scanning for components
• <context:component-scan base-package="org.example"/>

@Component
public class StudentService
{
@Autowired
StudentDAO studentDAO;
//constructors
//Getter setter methods
}
@Component
public class StudentDAO
{
@Override
public String toString() {
return "This is StudentDAO";
}
}
StudentService.java StudentDAO.java
23. DI: Using Annotations
<bean id="studentDAO" class="com.mindfire.spring.student.dao.StudentDAO"/>
<!-- Injecting studentDAO to StudentService via xml configuration -->
<bean id="studentService" class="com.mindfire.spring.student.service.StudentService">
<property name="studentDAO" ref="studentDAO" /> <!-- Setter injection -->
<constructor-arg ref="studentDAO"> </constructor-arg> <!-- Constructor injection -->
</bean>
<!-- This is used to auto scanning of beans annotated by @Component. -->
<context:component-scan base-package="com.mindfire.spring.student" />
