HOW TO RESOLVE ‘javac is not recognized as an internal or external command’ error in Java

javac is not recognized as an internal or external command’

When you run the java program for the first time on your computer the error message ‘javac is not recognized as an internal or external command’ error in Java  will be displayed because you have not set a complier to your program.

JAVAC is the compiler we use to compile the java program.

So how to add the javac to your program…

here is the tip..

Right click on the computer in the Start menu and click Properties.

My-Computer

then the below window will be opened…

In that click Advanced System Settings option…

AdvancedSystemSettings

Then a window will be opened in that click the ENVIRONMEN VARIABLE

Environment-Variable

 

Then the below will be opened

Environment-Variables

In that look for the option PATH IN THE SYSTEM VARIABLES

Path

Suppose if no path is found you can add it by clicking on New option.

then you have to set the path of your compiler here..

So open your jdk where you have installed

C

Program-Files

Open the JDK

jdk

Then Click on BIN

Bin

Then after opening the Bin copy the path by clicking the mouse on the above path

Copy-the-path

Now come to the System variable in Environment Variable

and paste the path that you have copied in the PATH and click semi-colon(for example

C:\Program Files\Java\jdk1.7.0_79\bin; )

set-path

Then click ok.

But one more thing is remained. That is setting up your CLASSPATH It is also in the SYSTEM VARIABLES if it is not found create it by clicking on New option.

Now it is time to set the path of library ‘lib’ found in the JAVA RUNTIME ENVIRONMENT ‘JRE’

JRE

LIB

Copy the path and paste it in the CLASSPATH in SYSTEM VARIABLES

Copy-the-path

new

CLASSPATH-CRATE

Type CLASSPATH in the Variable name: and paste the path that you have copied it in the Variable Value and click ok.

OK

Then click OK for Environment Variable and click ok for System Properties.

 

System-properties

Now you can confidently go and run the java program as I have posted in the last post “how to run a java program” if you have missed that click the below link to open to see How to run a Java program
