#

stark violet May 28, 2024, 7:42 PM

#

probably

stark violet May 28, 2024, 7:43 PM

#

coarse cobalt

Alternatively, you could also click the Search... button on the right here, select your program files directory and let Eclipse search through all subdirectories

coarse cobalt May 28, 2024, 7:44 PM

#

alright

#

#

stark violet May 28, 2024, 8:20 PM

In general, a JDK can do more than a JRE

In fact, every JDK contains a JRE
