import java.net.http cannot be resolved

Question

I'm trying to use HTTP GET and POST in Java but I can't import java.net.http. I have very little knowledge about this area, do I need to install something?

What Java version are you using? And how are you importing whatever class you're trying to import? (since `java.net.http` is a package, not a class) — Federico klez Culloca, Jan 05 '21 at 16:27
Please add an example to show how you are importing the package. — Soroosh Sarabadani, Jan 05 '21 at 16:28
Could you check which version of Java do you use? The package java.net.http was introduced in Java 11 — Andres Sacco, Jan 05 '21 at 16:44
I don't know which java version I'm using , an example would be import java.net.http.HttpClient. I'm using Eclipse IDE — Insanit, Jan 05 '21 at 16:47
You can check which version of Java do you use on Eclipse. Preferences -> Java -> Compiler (>11) and Preferences -> Java -> Installed JRE — Andres Sacco, Jan 05 '21 at 16:50
@Insanit you should also configure your OS and/or IDE to use it. — Federico klez Culloca, Jan 05 '21 at 17:09
I configured both the Installed JREs and Execution Environments on Eclipse but it still gives me a warning saying current version is 1.8 — Insanit, Jan 05 '21 at 17:14
Not sure if it's the right one but I found -vm C:\Program Files\Java\jre1.8.0_261\bin\server\jvm.dll in the Configuration — Insanit, Jan 05 '21 at 17:27

The problem is connected with the version of Java/JRE that exist in your system because the package "java.net.http" was included in Java 11 or up.

Try to download a new version of java from one of these sites Oracle JDK 11 or Open JDK

After installing the new version of Java check that Eclipse uses the correct one. To do this in your Eclipse go to Preferences -> Java -> Compiler and select 11, also go to Preferences -> Java -> Installed JRE and add the new JRE
