What are the steps to install Sun Java, where OpenJdk is already installed? [closed]

Why does rJava not work on Ubuntu 14.04 using OpenJDK 7?
java,r,openjdk,rjava,ubuntu-14.04
I had the same problem with a similar configuration (R 3.1.0, Ubuntu 12.10, 32-bit). I found the answer was in getting LD_LIBRARY_PATH set properly, as described here: error: unable to load installed packages just now except that the subdirectory in question is 'client' not 'server'. So now I'm setting my...

Is JavaFX supported on Openjdk?
The word "supported" means different things to different people. Here is the official JavaFX Supported Configurations page which describes the various platforms on which JavaFX2 is "certified". The page makes no mention of OpenJDK, so Oracle may take the position that JavaFX is "not certified" for OpenJDK. On the other...

The clear implication of this page is that you can cross-compile OpenJDK 8 with Hard Float support. (See the example commands towards the end ...) The page doesn't mention specific Java versions, so given that Oracle JDK 7 supports it it is likely that OpenJDK 7 will as well....

Difference between openjdk-6-jre, openjdk-6-jre-headless, openjdk-6-jre-lib
You are correct in that you will need a jre package to run any java application. Since you say you're running on an embedded platform I assume that the java app you want to run has no gui. In that case, you will be fine with openjdk-6-jre-headless. This is explained...
How to build the C code of OpenJDK 8 src.zip /launcher/
I am currently facing the same problem. Maybe it can be solved by providing jvm.h and jvm_md.h for your setup. Both contain-jvm-specific symbols and jvm_md.h contains additionally platform-dependent symbols. So you will need to choose jvm.h for your target jvm and jvm_md.h for your target platform. To get these headers...
Is `1/0` a constant expression in Java?
java,compiler-errors,java-8,openjdk,jls
The compiler is doing constant folding (precomputing trivial literal expressions). This is a case where the expression "completes abruptly", to use the JLS verbiage, disqualifying it from meeting the definition of "constant expression". So it's not a bug, it's consistent with the JLS. And yes, the expression doesn't evaluate to...
