Need Java installed on iPad. How can I do it?
Java isn't compatible with iPad or iPhone devices which means that you will not be able to install it or benefit from its features.
I've used the Cloud Browse app to access Java content. You have to buy a subscription, but it's worth it.

Java is compatible with the iPad, iPhone, etc., because the ARM processors that these devices use come with a Java Bytecode Processor by default. All Apple has to do is not disable it, and Java can be supported directly by the hardware.
