How can i tell if my Java is 32bit or 64bit?

[JEDI]

control panel -> java -> about -> version 8 update 60

doesn't tell me if it's 32 or 64bit.
or does it not matter?

(I have win 7 pro, 64bit.)

In Programs and Features it says Java 8 Update 60 (64-bit); this on Windows 8.1.

open a command prompt and type "java -version"

 

[JEDI]

open a command prompt and type "java -version"

C:\Users\UserName1>java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

so 64bit?

Keep in mind that 64-Bit Java only works for a 64-Bit Browser and 32-Bit Java only works on a 32-Bit Browser - So it you running both 32-Bit and 64-Bit Browsers you have to install both 32-Bit and 64-Bit Java.

Note: Always uninstall your old Java before installing an updated version.

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)

short answer is "MIXED MODE" means remove that outdated and very insecure version of Java and install the latest supported by your OS
