JMeter - Installation of JDK on Mac OS

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
