The hitch ...

The three BURNING questions in mind…

• What is Programming?

• What is Java?

• Why Learn Java?

What is Programming?

• Programming is giving a set of

instructions to a computer to
execute.

• Programming is the mental

process of thinking up instructions
to give to a machine (like a
computer).

• Coding is the process of

transforming those ideas into a
written language that a computer
can understand.
What is Java

• Java is a high-level, versatile, general-purpose, class-based, object-

oriented, and widely-used programming language.

• It was developed by Sun Microsystems (now owned by Oracle) and

is designed to be platform-independent, meaning it can run on various
systems without modification.

• Java uses an object-oriented approach, where programs are built

as collections of objects that interact with each other to perform tasks.
Why Learn Java?

• Despite been around for 27 years as of 2023, Java remains the 3rd most
popular and widely language worldwide.

• 90% of Fortune 500 companies still use Java for building high-performance
enterprise-level applications.

• Write Once, Run Anywhere (WORA) philosophy allows Java programs

to be executed on any platform with a compatible JVM. This portability is a
significant advantage over languages that are tied to specific operating
systems or architectures.
Why Learn Java (contd.) ?
Why Learn Java (contd.) ?
• Robust and Safe: Java was designed with a strong emphasis on safety
and robustness. Features like exception handling, access control, and
security mechanisms contribute to creating more reliable software.

• Java comes with a vast standard library that provides a rich set of
classes and functions, making it easier for developers to perform common
tasks without having to rely heavily on external libraries.

• Java has a massive and active community that contributes to its

continuous improvement. Additionally, the vast ecosystem of libraries,
frameworks, and tools provides developers with numerous resources to
enhance their projects.
Areas of Application
JDK Installation (for windows)

Download JDK 8:

• Go to the Oracle website or OpenJDK website (depending on your

preference for Oracle or open-source JDK).

• Locate the JDK 8 download page. Make sure to download the version
appropriate for your Windows operating system (32-bit or 64-bit).

Run the Installer:

• Once the download is complete, locate the downloaded file (usually named
something like "jdk-8uXXX-windows-x64.exe" for 64-bit or "jdk-8uXXX-
windows-i586.exe" for 32-bit).

• Double-click the file to start the installation.

JDK Installation (for windows)

Choose Installation Directory:

• The installer will prompt you to select the installation directory. By default, it
will be something like "C:\Program Files\Java\jdk1.8.XXX" (XXX represents
the update number). You can choose a different directory if you prefer.

Complete the Installation:

• Follow the on-screen instructions to complete the installation process. You

may be asked to accept the license agreement before the installation
proceeds.
JDK Installation (for windows)

Set Environment Variables:

• After installation, you need to set up environment variables so that your

system can locate the JDK installation.

• Right-click on "This PC" (or "My Computer") and select "Properties."

• Click on "Advanced system settings" on the left-hand side.

• In the "System Properties" window, click the "Environment Variables"

button at the bottom.

• Under the "System variables" section, click "New" to create a new variable.
JDK Installation (for windows)
• Set the variable name to "JAVA_HOME" and the variable value to the path
of your JDK installation (e.g., "C:\Program Files\Java\jdk1.8.XXX").

• Next, find the "Path" variable under "System variables" and click "Edit."

• Add a new entry with the value "%JAVA_HOME%\bin" to include the JDK's
"bin" directory in your system's PATH.

Verify the Installation:

• Open Command Prompt and type java -version to check if the JDK is
installed correctly. You should see the JDK version information displayed.
JDK Installation (for mac)

Download JDK 8:

• Go to the Oracle website or OpenJDK website (depending on your

preference for Oracle or open-source JDK).

• Locate the JDK 8 download page. Look for the version suitable for macOS.

Run the Installer:

• Once the download is complete, locate the downloaded file (usually named
something like "jdk-8uXXX-macosx-x64.dmg).

• Double-click the DMG file to mount it.

JDK Installation (for mac)

Install JDK:

• In the mounted disk image, double-click the JDK package file (usually
named something like "JDK 8 Update XXX.pkg").

• The macOS Installer will guide you through the installation process. Follow
the on-screen instructions to install JDK 8.

Set Environment Variables (Optional):

• By default, macOS sets the necessary environment variables for Java

automatically.
JDK Installation (for mac)

Verify the Installation:

• Open a new terminal window, and type java -version to check if the JDK is
installed correctly. You should see the JDK version information displayed.
Intellij IDEA Installation
