java is not recognized as an internal or external command solution

After installing jdk and setting the environment variables, entering the javac command in cmd cannot be used, prompting "javac is not an internal command or an external command, nor is it an operable program or batch file. ” But entering java -version can display the jdk version number normally, indicating that the java command is available. After I entered Java -home, I found that the path pointed to was completely wrong and the environment variable settings did not work. I don't know why.

Solution:

Run——>cmd

Run the following command in the console to set the java environment variable to solve the problem:

set java_home=C:\Program Files\Java\jdk1.6.0_26 The root directory where JDK is installed

set classpath=%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;

set path=%JAVA_HOME%\bin;

Note: The input is not case sensitive, and several Java commands are attached

java -help You can view the commands

java -home View JDK installation path

java -version View JDK version
