java - run multiple JDK's simultaneously -

i want know if can run multiple jdk's on pc , use them all

if can, value of path on system variable

thanks help

yes, can install many jdks like. put them in different folders.

the 1 refer on path choice - presumably you'd choose 1 want use whenever type "java ...." commands @ command line. in absence of other factors should set recent jdk version.

note ide may support multiple jdks, example eclipse has "preferences / java / installed jres" can set multiple jdks/jres use eclipse.
