The CMD uses the PATH environment variable to search for executables (java.exe). The executable is searched in the directories listed in that variable, in the given order. The first one found, is the one that is executed.

Eclipse uses its own settings:

  1. the JRE used to start Eclipse can be specified in the eclipse.ini file; if not specified there, the OS default will be used (usually the same as the CMD, see above);

  2. the JRE used to execute an application inside Eclipse, is specified by the Run/Debug configurations (Run-Run Configurations.../Run-Debug Configurations...), the respective project properties (Project-Properties) and Eclipse preferences (Window-Preferences-Java-Installed JREs).
