How to check which version of JRE
the eclipse is using ?
This section :
Window--->Preferences--->Java
shows by the name of JDK :
<Please see the following figure.
To see which Java Eclipse itself is using go to Help > About Eclipse
click Installation Details
and look at the Configuration
tab.
When you run Java programs from Eclipse you can select which Java is used. Preferences > Installed JREs
lists the JREs (and JDKs) that Eclipse knows about. The Run Configuration
for the program shows which Java is used to run the program.
Open the About Eclipse dialog (Help -> About Eclipse on Windows, Eclipse -> About Eclipse on OS X)
Click "Installation Details", choose the Configuration tab, and scroll down to the "java.home" entry. The value is the path name to the JVM used.
Goto Window->Preference->Installed JRES
or Goto Project , right click Preference -> Jva Build Path -> libraries
