0.08 -> hello today we are going to solve this
problem that happens when you try to run your
6.8 -> java code in visual studio code
so let's see what is the problem
17.2 -> if you compile your code like this main.java it's
at the fully compiled but when you run the file
29.84 -> main then space error could not find or
load main class so the problem is it is java
39.28 -> who is not able to find your main class
so we have to do something about it
46.56 -> so the first problem could be you have not saved
your java file this would be the reason for this
55.04 -> error so to save your file you can go into file
menu and click on save or you can enable auto
62.96 -> save so that you don't have to always save
your port it will automatically save itself
68.48 -> now let's again run this code java main oh it
is still complaining us that class is not found
83.36 -> so no we have to first
compile the file and then main
91.76 -> main dot java
96.08 -> now you can see that a class file has been created
now let's try to run this classify java main
108.48 -> again it is showing an error could
not find or load the main class name
115.52 -> so this error is telling you that java is not
able to find your class file this class file
123.52 -> although it is in the same folder it is not able
to find it so we have to tell the class path
130.88 -> so to run this file we have to
write java dash class path and
139.6 -> dot main that's it you can see that hello world
is printed and this means that the class file is
150.72 -> present in the current directory this dot means
current directory but many times people prefer
157.76 -> to use this play button to run their code
you can see that if i use this play button
165.76 -> this is showing mirror why because
here compilation is done and after
171.04 -> compilation it is directly trying to execute
the main class so we have to change this stuff
177.36 -> so that it does not show us error so let's
do it go into settings and click on this icon
186.8 -> let's close this and this is your code runner
executor map this is how your code runner
194.16 -> extension is able to run your code it
basically throws this command into your
199.84 -> terminal so let's write this
thing over here java class path
208.56 -> and
212.08 -> done that's it
216 -> yeah and you are done now
let's go back and run your code
222.88 -> now you can see that hello world is printed even
when we are running it with the extension core
228.88 -> runner extension so that is how you solve the
problem and one more thing make sure your java
235.2 -> compiler and executor are properly properly
properly added in the environment variable
243.84 -> you can do that by going into the environment
variable settings and change it environment
251.2 -> variables and then you go into path and here
you can see this is the location of my java jdk
260.64 -> that's it so make sure you have this otherwise
your code will also not run so that's it
