在哪里可以找到 java.net.http package Jar 文件？

Question

I have searched too much but still didn't find nothing. I want a jar file which contains these classes.

import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

My compiler doesn't support these imports. So, I want a jar. Please help me

Answer 1

You can find it at this link for the OpenJDK version (here for the JDK 11 version):

https://jdk.java.net/java-se-ri/11

Steps:

• download the full JDK for the version and platform that you need (os, linux or win).
• unzip it, navigate to the jmods folder
• find the java.net.http.jmod file. Use it "as is" or rename it to java.net.http.jar

Answer 2

jdk8 does not contains these classes,you can use URConnection connection = URL.openConnection()
