Does installed java jre need to first be uninstalled before installing a java jdk, or can the presently installed jre be allowed to stay in place when installing jdk?

" Do you want to run Java programs, do you want to develop Java programs, or do you want a Java Runtime Environment (JRE) on a server? If you want to run Java programs, but not develop them, download the JRE. If you want to develop Java applications, download the Java Development Kit, or JDK. The JDK includes the JRE, so you do not have to download both separately. If you need the JRE on a server and do not want the ability to run RIAs, download the Java SE Server JRE. This version of the Java SE Server JRE does not include the Java plug-in or Java Web Start support, additional tools might be removed from future versions."

 

So....I would uninstall it, otherwise you will end up with two installations of the jre.

It doesn't hurt to have two JRE's on your system. Java developers often have even more in different versions for testing, because sometimes you want to have backward compatible programs that run on older versions, and sometimes you just want to use the newest features of the Java language and the code will only run on the newest runtime version. The version that is used as default if you run Java programs, is defined in the JAVA_HOME environment variable. See here how to set JAVA_HOME: http://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/index.html
