How to check Installed Java is a 32 bit or 64 bit version ?


If you have installed JDK, Java would have registered in the system environment variables.

Go to command prompt and type “java –version”

C:\Users\kh1205>java -version
 java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)

If it’s a 64 bit Java, you will be finding “64-Bit Server VM” in the above line.

If it’s a 32 bit java, you will be finding “Client VM” in the above line.

I have another JDK configured in my system, for which I wanted to check java version.
For example, other version of java is available in the location “C:\Program Files (x86)\Java\jdk1.6.0_31

C:\Program Files (x86)\Java\jdk1.6.0_31\bin>java -version
 java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
Java HotSpot(TM) Client VM (build 20.6-b01, mixed mode, sharing)


“Client VM” in the last line tell you that,  JDK is a 32 bit version.
