How to Install Java 1.8 on MacOS

In recent years, Apple has transitioned from Intel-based processors to ARM-based processors in their MacBooks. This change brings about various opportunities for developers and end-users alike. One of the most significant implications is the need to install a compatible JDK (Java Development Kit) on your Macbook M1.

To compare the performance of the new Macbook Air M1, I conducted a test by starting a Spring Boot application locally on each computer. The results were astonishing - the application started in just 12.953 seconds on the Macbook Air M1 with 8GB RAM and MacOSx. In contrast, it took 9.8 seconds to start the same application on an Intel i7-based Windows machine with 12GB RAM.

To install Java on your Macbook M1, you'll need to look for a version compatible with ARM processors. One option is Azul's distribution, which can be found on their website. Another option is the JDK developed by Microsoft for ARM processors, available on GitHub.

Before installing a JDK, ensure that you have Rosetta 2 installed, as it will facilitate the transition process and allow apps that work with Intel to still function smoothly using Rosetta 2. This marks the beginning of a transition period where developers will need to adapt their applications to the new architecture, similar to when Apple moved from PowerPC to Intel in 2006.

The ARM-based processor has several advantages over its Intel counterpart. ARM processors use reduced instruction set computing (RISC), which enables them to execute instructions in one cycle, whereas Intel processors require multiple cycles for complex instruction set computing (CISC). This change also opens up opportunities for developers to create apps that work across all Apple platforms, including MacOS, iOS, and iPadOS.

In conclusion, installing Java 1.8 on your Macbook M1 requires finding a compatible JDK version and installing it correctly. The transition from Intel-based processors to ARM-based processors brings about exciting possibilities for developers and end-users alike. With the right tools and knowledge, you can take advantage of the new architecture and create innovative applications that run seamlessly across all Apple platforms.
