Here, we experimentally verified that a quantized current-biased Josephson junction (CBJJ), as an artificial macroscopic \"particle\", can be served as either boson or fermion, depending on its biased dc-current. By using the high vacuum two-angle electron beam evaporations, we fabricated the CBJJ devices and calibrated their physical parameters by applying low-frequency signal drivings.
