I'm trying to install JDK-18 on my windows machine, but the installer gets closed immediately. Previously I had installed Java 8(Update 311) for some reason and its installation file is missing now. What should I do to install JDK-18 freshly and remove Java 8 entirely? These Java SE 8 update releases are provided under the Binary Code License (“BCL”). Java SE 8u211 and later updates are available, under the Java SE OTN License. For production use Oracle recommends downloading the latest JDK and JRE versions and allowing auto-update. Only developers and Enterprise administrators should download these releases. I guess I need to downgrade to JDK 11. Java Platform, Standard Edition 11 Reference Implementations is the only place I can get JDK 11. However it seems to be a binary, not a setup. Checking C:\Program Files\Java I found a folder for jdk-17 and jre1.8.0, so I copy the folder jdk-11 I just download to there. Checking the path environment I see FROM alpine:latest ENV JAVA_HOME=/usr/lib/jdk ENV PATH=${PATH}:${JAVA_HOME}/bin # Default to UTF-8 file.encoding ENV LANG='en_US.UTF-8' LANGUAGE='en_US:en' LC_ALL='en_US.UTF-8' # (Optional) Add extra packages for fontconfig and ttf-dejavu to support server-side image generation RUN apk add --no-cache fontconfig libretls musl-locales musl I tried the solution of @Ralf Ulrich and it works for me. I tried it on kaggle. 1- first install install-jdk via pip install install-jdk. 2- then run this code to install java-11 and add it to enviroment variable Note: On Windows 7 click on the Windows button. Click on the "Edit system environment variables" shortcut. Wait for the environment variables window to open. Click on "New…". Enter "JAVA_HOME" as variable name. Enter the [JAVA_INSTALL_DIR] as variable value. In this tutorial, the Java installation directory is C:\jdk-11.0.1. Click OK. How to Install.
