The average bottom-hadron and individual B+, B-0, and B-s(0) meson lifetimes have been determined using decays with a J/psi --> u(+)u(-) the final state. The data sample consists of 110 pb(-1) of pp collisions at root s = 1.8 TeV collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995. For the average lifetime of B hadrons decaying into J/(psi + X, we obtain [tau(b)] = 1.533 +/- 0.015(stat)(-0.031)(+0.035) (syst) ps. For the B+ and B-0 meson lifetimes, we determine tau(B+) = 1.68 +/- 0.07(stat) +/- 0.02(syst) ps, tau(B-0) = 1.58 +/- 0.09(stat) +/- 0.02(syst) ps, and tau(B+)/tau(B-0) = 1.06 +/- 0.07(stat) +/- 0.02(syst). For the B-s(0) meson lifetime, we find tau(B-s(0)) = 1.34(-0.19)(+0.23)(stat) +/- 0.05(syst) ps.
