Can you install Java on an Ipad?
No.
Well, darn.
Thanks.
Hang on; take a look at QMole, which has a JVM built in to allow running Java code using the GTK toolkit for graphics display. There is also a JVM compiler which will run code natively as well as a number of different web-based editor/compiler solutions. Note this doesn’t make a fully featured JVM environment such that you could run any arbitrary Java code on an iPad (nor is the iPad really suited to run a resource-heavy, poorly optimized complex Java-based application) but if you are looking to do some development in Java you could certainly use either of them for mobile work.
If you actually want to build applications to run natively on iOS, they should be in C, Objective-C, or Swift. iOS is not intended to be an open platform to support virtual machine applications (though I’ve had pretty good luck running Python code in its VM on an iPad). If you are trying to run some Java code intended to run on a desktop machine, you’re probably going to be disappointed even if you can get it to compile to bytecode and run even if all of the necessary libraries you need are available (unlikely).

Thanks, Stranger.
I want to open a browser and get into an HP switch and display port usage.
It appears that I’ll have to go with a laptop instead.
You can do that easily on iOS, just not with Java.
