Adding JDK "bin" Directory to Path Setting
This section provides a tutorial on how to add JDK 'bin' directory to the 'path' system environment variable.
If you are using a Windows computer and want to run Java compiler and JVM by typing their program file name without the directory path name, you may need to update the "path" environment variable on your Windows computer:
Then I ran the "echo %path%" command in a new command window to confirm the change:
herong> echo %path% C:\Progra~1\java\jdk-17.0.1\bin; C:\WINDOWS\system32;C:\WINDOWS; ...
Now I should be able to run Java commands without the directory path name:
herong> java -version java version "17.0.1" 2021-10-19 LTS herong> javac hello.java herong> java Hello Hello world!
Now I am ready to play with Java Swing functionalities included in Oracle JDK package!
You can also set a new environment variable called "java_home" to avoid typing the full path name to access Java tool program files:
herong> set java_home=C:\Progra~1\java\jdk-17.0.1 herong> %java_home%\bin\java -version java version "17.0.1" 2021-10-19 LTS
