The JDK and the JRE have minimum processor, disk space, and memory requirements for 64-bit Windows platform.

Before installing the JDK or the JRE on your 64-bit Windows platform, you must verify that it meets the following minimum processor, disk space, and memory requirements.

Java Runtime Environment (32bit) 8.0.2210.11. Oracle - 66.32 MB Freeware. Java Runtime Environment (JRE) is Java’s most basic virtual machine. It’s a required component to run any Java-based application or web applet. Prebuilt OpenJDK Binaries for Free! Java™ is the world's leading programming language and platform. AdoptOpenJDK uses infrastructure, build and test scripts to produce prebuilt binaries from OpenJDK™ class libraries and a choice of either OpenJDK or the Eclipse OpenJ9 VM. All AdoptOpenJDK binaries and scripts are open source licensed and available for free.

Processor Requirements

Eclipse is an open source community. Find downloads for packages, developer builds, and projects.

Both the JDK and JRE require at minimum a Pentium 2 266 MHz processor.

Disk Space Requirements

For JDK 9, you are given the option of installing the following features:

When you install 64-bit JDK, then 64-bit public JRE also gets installed. The following table provides the disk requirements for the installed features:

JDK	Installed Image
Development Tools: 64-bit platform	500 MB
Source Code	54.2 MB

JRE	Installed Image
Public Java Runtime Environment	200 MB
Java Update	2 MB

Memory Requirements

On Windows 64-bit operating systems, the Java runtime requires a minimum of 128 MB of memory.

The minimum physical RAM is required to run graphically based applications. More RAM is recommended for applets running within a browser using the Java Plug-in. Running with less memory may cause disk swapping, which has a severe effect on performance. Very large programs may require more RAM for adequate performance.
