FAQs on #1.1 Kotlin Setup on Windows: How to Install JAVA JDK for Coding in Kotlin Video Lecture - Kotlin Tutorial for Beginners: Learn Kotlin in easy language - Back-End Programming
| 1. How do I install the JDK on Windows? |  |
Ans. To install the JDK on Windows, you can follow these steps:
1. Visit the Oracle website and download the JDK installation file for Windows.
2. Run the downloaded file and follow the installation wizard.
3. Choose the destination folder for the JDK installation.
4. Set the environment variable "JAVA_HOME" to point to the JDK installation directory.
5. Add the JDK's "bin" directory to the system's PATH variable.
6. Verify the installation by opening a command prompt and running the command "java -version".
| 2. What is the purpose of installing the JDK for Kotlin back-end programming? | |
Ans. The JDK (Java Development Kit) is required for Kotlin back-end programming because Kotlin is fully compatible with Java. Kotlin compiles down to Java bytecode and runs on the Java Virtual Machine (JVM). Therefore, the JDK provides the necessary tools and libraries to develop, compile, and run Kotlin applications on the server-side. It includes the Java compiler, runtime libraries, and other utilities required for Kotlin development.
| 3. Can I use a different version of the JDK for Kotlin back-end programming? | |
Ans. Yes, you can use a different version of the JDK for Kotlin back-end programming, as long as it is compatible with the Kotlin version you are using. Kotlin is compatible with JDK versions 6 and above. However, it is recommended to use the latest stable version of the JDK to benefit from bug fixes, performance improvements, and new features. It is important to ensure that the JDK version you choose is supported by the Kotlin compiler and runtime.
| 4. How can I set the JAVA_HOME environment variable on Windows? | |
Ans. To set the JAVA_HOME environment variable on Windows, you can follow these steps:
1. Right-click on "This PC" or "My Computer" and select "Properties".
2. Click on "Advanced system settings" on the left-hand side of the window.
3. In the System Properties window, click on the "Environment Variables" button.
4. In the "System Variables" section, click on "New" to create a new variable.
5. Set the variable name as "JAVA_HOME" and the variable value as the JDK installation directory path.
6. Click "OK" to save the changes.
| 5. How do I add the JDK's "bin" directory to the system's PATH variable? | |
Ans. To add the JDK's "bin" directory to the system's PATH variable on Windows, you can follow these steps:
1. Open the "Environment Variables" window as mentioned in the previous question.
2. In the "System Variables" section, select the "Path" variable and click on "Edit".
3. In the "Edit Environment Variable" window, click on "New" to add a new entry.
4. Enter the path to the JDK's "bin" directory (e.g., "C:\Program Files\Java\jdk1.8.0_221\bin") and click "OK".
5. Click "OK" again to save the changes.
6. Restart any open command prompt windows for the changes to take effect.

hi Lisa Tsering Siddarth from smarter
welcome to the next video of this course
of Cortland basics and fundamentals now
in this video let us install the
software's for both Windows and Mac OS
so first of all we will install the
required software's for Windows and
later on if you are using Mac OS then
simply skip this video and jump onto the
video of installing software's for the
Mac so in this video first we are going
to install the Java JDK for Cortland now
you must be wondering we are about to
start the course on Cortland so why do
we require the Java JDK
now the cortland requires the java
virtual machine to execute its program
so we need to have this Java JDK that is
the Java development kit that contains
the compiler and the interpreter and
also the Java Runtime environment with
the help of which we are going to
execute our Kotlin programs so let us
now proceed and install java jdk in our
Windows PC so here first simply go to
google and simply search for Java JDK
for windows hit enter and you will get
the first link from the oracle.com so
here simply click on it you will be
navigated to the official page of
oracle.com where you can simply download
the java for windows now here you can
see Java SE downloads now the SE stands
for the standard edition right and here
on the right you will find Java EE and
Java ME so here Java EE stands for
Enterprise Edition right so but we will
simply install the Java standard edition
so simply select it and now down the
side you will find the java SE
development kit with the version name so
here I will simply accept the license
and down the side you will find the
windows 64-bit machine and the Java for
windows 32-bit machine now my machine is
64-bit so I will simply download this
version and if you
not aware of how much bit is your PC
then simply navigate to file explorer
and then right-click on this PC and
click on properties here you will find
the system type so my PC is 64-bit so I
will simply download this file and if
you are using the 32-bit PC then simply
download this file that belongs to x86
right so simply download this file so
after you download the Java JDK you will
find it inside the default downloads
folder or wherever you have downloaded
it so I will simply double click on it
and launch the application hit on yes
and then simply install it as we install
any other application
and now hit on next so it will take some
time to install Java in your laptop
so here it says the java jdk has been
successfully installed and now hit on
close now to verify whether the java has
been installed in your pc or not for
that simply open your command prompt
so simply type CMD and then here simply
right-click on it and then run as
administrator and here we are currently
under the system32 folder so simply type
CD and then hit enter sorry
CD space dot dot hit enter and now
simply type Java hit enter so here you
will get all this in front of you that
simply shows what are the Java commands
that you can use with this Java command
so if you get this then your Java has
been installed in your PC otherwise
please follow the steps again
and now down the side let us check out
which version of Java we have installed
so simply type Java space - version hit
enter and then you will get all the
details of the Java installed and now
after installing Java in your PC where
are all the files stored so all the
files related to Java has been stored
inside the C Drive and then simply
navigate to Program Files here you will
find the Java folder and here you will
find this jdk 1.8 point 0 1 3 1 that we
have installed right now and these are
the other versions of Java that I need
to clean up and this is the JRE that is
installed alongside
now what this JDK stands for and what
this JRE stands for I will let you know
shortly in our upcoming videos so as of
now catch you guys in the next video
where we will complete our software
installation thank you
