Java is a very popular programming language which provides a different component in order to run, develop Java applications. JRE or Java Runtime Environment is used to run Java application. JDK or Java Development Kit is used to develop Java applications. In this tutorial, we will learn how to set up Java, JRE, and JDK operating system path variables in order to work properly.
Open Environment Variables. Below we can see the environment variables menu where we will create the JAVAHOME system variable and set the path accordingly. We click to the New in order to create a new system variable. Create New System Variable. Here we will set the Variable Name as JAVAHOME and the Variable Value the path or Java, JRE or JDK. https://openfasr789.weebly.com/etcher-mac-os-download.html.

Before starting the configuration we have to locate the JRE or JDK path. JRE or JDK generally installed on the
Program Files
or Program Files(x86)
directory under the Java directory like below.and under the
Java
directory the JDK is residing.Now we have learned the path of the Java, JRE or JDK installation. We can set this path as Java HOME_PATH environment variable. We will open the computer properties with by running
sysdm.cpl
in the Run menu like below. We can also open it from the File Explorer -> Computer -> Right Click.In the system properties, we will navigate to the
Advanced
tab which provides the Environment Variables
button like below.Below we can see the environment variables menu where we will create the
JAVA_HOME
system variable and set the path accordingly. We click to the New
in order to create a new system variable.Java Options Environment Variable Windows
Here we will set the
Variable Name
as JAVA_HOME
and the Variable Value
the path or Java, JRE or JDK which is C:Program FilesJavajdk-12
in this example. Then we will click OK.If we want to run
java.exe
or similar executables provided by JRE or JDK we have to add the path of Java in the Path
variable like below. Mac bootcamp download windows 10. We select the system variable named Path
and click to the Edit

Here we click to
New
which will add a new line to the existing values.Eclipse Environment Variables Java
Here we will set the
bin
folder path which is C:Program FilesJavajdk-12bin
in this example.Java_options Environment Variable Weblogic
Then we will click
OK
and OK
in the environment variables screen which will save and activated new path configuration.Java Environment Variables Windows
We can check the new path configuration simply opening a new command line interface MS-DOS. Then just type
java -version
which will execute java.exe
with the -version
option. We can see the current java binary version by running it.
