Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J4 is significantly lighter (428g ) than the Pentax K100D which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Pentax K100D has an APS-C sized sensor and Nikon 1 J4 has a smaller 1" sensor, Nikon 1 J4's lenses for a similar focal length and aperture will generally be lighter and smaller than the Pentax K100D lenses.

LCD Screen Size and Features
Nikon 1 J4's 3" LCD screen is slightly larger than Pentax K100D's 2.5 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Nikon 1 J4 has a 18.0MP 1" (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Pentax K100D has a 6.0MP APS-C (23.5 x 15.7 mm ) sized CCD sensor .
Nikon 1 J4's sensor provides 12MP more than Pentax K100D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 1 J4 and K100D sensor size comparison.

Sensor Size and Resolution Comparison image of Nikon 1 J4 and Pentax K100D Cameras
As seen above, Pentax K100D has a 3.2x Larger sensor area than Nikon 1 J4. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Pentax K100D has an advantage over Nikon 1 J4 There are 151 lenses for Pentax K100D's Pentax KAF mount, on the other hand there are only 13 lenses for Nikon 1 J4's Nikon 1 lens mount.
Another important factor is the availability of image stabilization. Pentax K100D has a big advantage in this regard because it has a sensor based image stabilization which means that all the lenses mounted to this body will be stabilized. On the other hand, Nikon 1 J4 doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 7 lenses for Nikon 1 mount with Optical Image Stabilization features.
