The problem of coexistence between charge-density-waves (CDWs) and superconductivity is revisited. Recent
 evidence was analyzed for different classes of materials with the emphasis on high-Tc oxides. For the latter,
 the model of the d-wave or extended s-wave Cooper pairing competing with checkerboard or unidirectional
 CDWs is suggested. The corresponding phase diagrams were plotted and used as a guide to predict new features
 in the tunnel or photoemission spectra. In the framework of the model concerned, dc Josephson tunneling
 through junctions involving CDW superconductors is examined. It is shown that CDWs distort current dependences
 on the angle between crystal axes and the junction plane inherent to d-wave superconductors leading to
 an extra periodicity.
