检查solaris Sparc上JRE的安装版本是否为64位

Question

Is there a clear or easy way to check over the command line if the installed JRE is 64 bit on a Sparc machine?

I am used to seeing this in:

java -version 

however it appears that Solaris only says what version and build of java is installed.

Answer 1

Run java -d64 -version . It will complain if a 64 bit JVM isn't installed.

Answer 2

如果d （小写）不起作用，则将D置于大写。
