  Static spherically symmetric black holes and particle like solutions with
self interacting minimally coupled scalar field {\phi} are analyzed. They are
asymptotically flat or anti-de Sitter (AdS). We express them in terms of a
single function {\rho} which undergoes simple conditions. If {\phi} is
nontrivial the ADM mass M has to be positive. No-hair theorems are generalized
to the AdS asymptotic. For both asymptotics the Killing horizon is
nondegenerate and its radius cannot be bigger than 2M. Derivatives of {\rho} at
singularity determine properties of admissible potentials V({\phi}) as
regularity, boundedness and behaviour for maximal values of {\phi}. Several
classes of solutions with singular or nonsingular potentials are obtained.
Their examples are presented in a form of plots.
