Back technology work. I was planning to write backend with Java, while other friend writing frontend with React Native.
For my first time, I would like to start with easy level. SpringBoot is what I am looking for. At least java version of 17 is required for Spring 3.0 but my computer preinstalled java 16 already. I need to upgrade the java version. What popped up in mind is sdk manager, the version control tools recommended by my senior. I would like to do it on my own so I skipped this method and looking for the other ways.
I downloaded the long term support version(LTS) of java by chocolatey.
```
choco install openjdk — version=21.0.0
java -version
```
The version of my computer still remains to be v16. I remember that the JAVA_HOME and PATH in environment variables should be updated.
You could refer to this link to see how to update the variables:
https://www.java.com/en/download/help/path.html
In my mind, java should be updated as the path was pointed to the installed version. HOWEVER, in windows 10, there is a preset PATH you need to remove it from the list. That is ```C:\Program Files (x86)\Common Files\Oracle\Java\javapath``` , you mind try to find where is yours located.
After removing the path from PATH in system variables, java version finally got updated.
One step closer to build the server!!
