Easy steps to Install JDK on Mac:
1. Check if JDK is Pre-Installed:
In some Mac systems (earlier than Mac OS X 10.7 Lion), JDK has been pre-installed. To check if JDK has been installed, open a "Terminal" (Finder ⇒ Go ⇒ Utilities ⇒ Terminal) and type this command:
javac -version
- If a JDK version number is returned (e.g.,
JDK 1.x.x), then JDK has already been installed. If the JDK version is prior to 1.7, proceed to Step 2 to install the latest JDK followed by Step 3. - If the message "command not found" appears, JDK is not installed. Proceed to the "Step 2: Download JDK".
- If the message "To open javac, you need a Java runtime" appears, select "Install" and follow the instructions to install JDK.
2. Download JDK:
- Goto Java SE download site http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Under "Java Platform, Standard Edition" ⇒ "Java SE 8u{xx}" ⇒ Click the "JDK Download" button
- Check "Accept License Agreement"
- Choose your operating platform, e.g., "Mac OS X" (
jdk-8u{xx}-macosx-x64.dmg). Download the installer.
3. Install JDK/JRE:
- Double-click the downloaded Disk Image (DMG) file. Follow the screen instructions to install JDK/JRE.
- Eject the DMG file.
- To verify your installation, open a "Terminal" and type "javac -version" commands
