Install Java Mac
To install Java on a Mac, you can follow these steps:
Note: Starting with macOS Catalina (10.15), Apple no longer includes a pre-installed version of Java. You need to install it manually.
Check if Java is already installed:
Open Terminal, which you can find in the Utilities folder within the Applications folder, or by searching for “Terminal” using Spotlight. Then, run the following command to check if Java is already installed:
bashjava -version
If Java is installed, you’ll see information about the installed version. If it’s not installed, you’ll receive a message indicating that no Java runtime is present.
Install Java:
If Java is not installed, you can install it by downloading and installing the official Oracle JDK or by using the Homebrew package manager.
Option 1: Install Oracle JDK (Recommended for Most Users):
- Visit the Oracle JDK download page: Oracle JDK Download
- Download the latest version of Oracle JDK for macOS.
- Open the downloaded
.dmg
file and follow the installation instructions.
Option 2: Install Java with Homebrew (For Advanced Users):
If you prefer using Homebrew, you can install Java using the following commands:
Install Homebrew (if not already installed):
bash/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Install Java using Homebrew:
bashbrew tap AdoptOpenJDK/openjdk brew cask install adoptopenjdk11
This command installs AdoptOpenJDK 11, which is a popular open-source distribution of Java.
Verify the Installation:
After installing Java, open a new Terminal window and run the following command to verify the installation:
bashjava -version
You should see information about the installed Java version.
That’s it! You have successfully installed Java on your Mac. You can now use Java for development or to run Java applications.
