I accidentaly erased some java folders from my computer which is running 10.4.8. So all java applications don't work for now. I tried to reinstall java, but I couldn't find a way to do it. Java doesn't appear on software update, also I downloaded some Java packages from apple's webpage to. Using Java in Mac OS X Published August 6th, 2012 at 4:33 PM EDT, modified October 19th, 2012 at 3:15 PM EDT Many people using the latest versions of Mac OS X (10.7, aka Lion, and 10.8, aka Mountain Lion) have had problems getting Java applets to run.
If you would like to learn Java programming, the best way is by writing Java codes by yourself. To compile the Java codes then you need Java Development Kit (JDK). It can be Oracle JDK or OpenJDK. This post guides you how to install Oracle JDK 8 on Mac OS X 10.10 Yosemite. It should be also applicable for previous version of OS X such as OS X Maverick, Mountain Lion, and OS X Lion. At the time of this post written, the latest version of JDK is JDK 8 Update 25.
Basically I previously had written an article how to install Java SE 7 / JDK 7 on Mac OS X Lion. I just would like to rewrite on the newest version.
1. Download Oracle JDK 8 from Oracle website. You need to accept license agreement to be able to download the file. Make sure you select the Mac OS X x64 platform (jdk-8u25-macosx-x64.dmg).
2. Double-click the downloaded file ‘jdk-8u25-macosx-x64.dmg' and follow the on-screen installation.
3. Once it is successfully installed, it is installed inside /Library/Java/JavaVirtualMachines folder.
4. Verify that the system is now using JDK 8.
5. If you would like to uninstall JDK 8, simply remove the jdk1.8.0_25.jdk
Hopefully this tutorial helps you on installing JDK 8 / Java SE 8 on Mac OS X 10.10 Yosemite.
With Oracle's Java 8, there's been some confusion as to whether Java 8 runs on Mac OS X 10.7.5. This issue was lent additional urgency in the wake of Oracle's announcement that they will begin auto-updating Java 7 users to Java 8 starting in January 2015.
The root of the confusion lies in the fact that Oracle has listed two different sets of system requirements on their website for Macs running Java 8 on Mac OS X.
The first set is available via Oracle's general Java system requirements page. This page states that Java 8 requires the following:
- Intel-based Mac running Mac OS X 10.8.3+, 10.9+
- Administrator privileges for installation
- 64-bit browser
The second set is available via the Java download page for Mac OS X. The system requirements linked from the download page state that Oracle's Java requires the following:

In short, the question of Java 8 support for 10.7.x depended on which system requirement page was correct. For more details, see below the jump.
Based on my testing, it appears that the current version of Java 8 (Java 8 Update 25) installs on Mac OS X 10.7.5 without issues. Dwl g510 for mac.
Following installation, I tested on a 10.7.5 Mac against the following sites:
My work's Juniper VPN (which uses a signed Java applet)
Oracle's Java Test page: https://www.java.com/en/download/help/testvm.xml
Java Tester's Java Version page: http://javatester.org/version.html
Mac Install Java 8
In all three cases, the Java applets on those sites launched and worked without issue using Java 8 Update 25 (though the javatester.org applet needed to be whitelisted.)
