Java command not found

I'm new to everything I mention here so this makes it a little bit hard for me.
I wanted to install Selenium driver to run codeception acceptance tests.
I downloaded selenium server, copied the selenium-server-standalone-3.0.0-beta2.jar in the same path as I save my tests.
then I ran the java -jar selenium-server-standalone-3.0.0-beta2.jar on Git Bash according to codeception help on installing Web Driver. I got the error
bash: java: command not found
anybody knows what's wrong here?
java is not installed or it isn't present in PATH.

How to run Java Programs
(4 answers)
Closed 4 months ago.
I'm running a Java program on a Chromebook, and I'm trying to run the file in the Linux terminal. I ran the command javac Main.java, but it shows nothing, not an error, but just straight up nothing.
I have Java installed. The file I'm running has no bugs. I did not make a typo. Everything is perfectly right.
Is there something I'm missing?
user#penguin:~$ javac Main.java

Java path..Error of jvm.cfg
(23 answers)
Closed 2 years ago.
I am able to compile the java program but not able to run it.
The problem is that java cannot open the .cfg file which is part of JRE 8.
Firstly check if you have permission for running jar.
Then check it your runtime is same as JDK.
Check if you are typing command correctly:
java -jar file.jar
Edit:
It seems like your .cfg file doesn’t exist or it’s corrupted.
Check it and try rebuild it. If it didn’t work you have syntax error somewhere int cfg file.

Issues understanding how to use Jython
(1 answer)
Closed 4 years ago.
I just found out about Jython and I really wanted to use it. Please forgive me if I'm doing something wrong and please explain.
I made a simple python program to test Jython, test.py. When typing
jython test.py
in the command prompt it run normally. So I decided to make a Java .class file. Since jythonc doesn't exist anymore, I tried
jython -m py_compile test.py
and a .class file was created in the same directory called test$py.class.
(this is equivalent to
>>> import py_compile
>>> py_compile.compile('test.py')
as I tried as well)
However, when I tried
java test$py
it threw me an exception:
Error: Could not find or load main class test$py
Caused by: java.lang.NoClassDefFoundError: org/python/core/PyRunnable
(I also tried with classpath but it did the same exception)
What does it mean? How can I solve it?
Note: I've downloaded Jython 2.5.4rc1.
This could be a corrupted installation of jython as per simillar Linux: NoClassDefFoundError org/python/core/PyException #1006 issue. If you can find jython-standalone-2.5.3.jar and it's not corrupted you may want to try re-downloading and re-installing jython.

how to make makefile for java with external jar file
(1 answer)
Closed 8 years ago.
I want to write a Makefile that compiles and runs the following code. My question here is how to add an external library using Make syntax?
javac -cp commons-cli-1.2.jar Iperfer.java
java -cp .:commons-cli-1.2.jar Iperfer -c -h localhost -p 1234 -t 12
My question here is how to add an external library using Make syntax?
The Answer is in the question. You would use the same command as you would from the command line ...
This is really a Java agnostic question. It is really about how to write a Makefile. But presumably if your teachers want you to use make to build Java, they will have provided you with a sample / template Makefile to get you started. If you showed us that template, we could tell you how best to modify it.
But assuming that you don't have a specific template in mind, then this a duplicate of an existing Question.

javac not recognized
I'm starting in the world of programming in java and I have run across a big problem: i cant compile my programs. when I type the javac command in cmd.exe(im using Windows 7) it displays this:
'javac' is not recognized as an internal or external command, operable program or batch file.
So I can't even test my first program.
I found in a book the following command:
set path=%path%;c:\java\jdk1.6.0\bin
but it doesnt work either.
I downloaded the newest version of the Jdk package just 2 weeks ago.
Look through your C drive for the c:\java folder and make sure you have version 1.6.0 of the jdk
c:\java\jdk1.6.0\bin
This will only work if you give it a path that actually exists. If you don't have 1.6.0, then type in:
set path=%path%;c:\java\<YOUR_ACTUAL_JAVA_VERSION_DIRECTORY>\bin
