Chemical compositions of variety types of stars contain useful information to constrain the nucleosynthesis in the universe and chemical evolution of galaxies. The products of nuclear reactions inside stars sometimes appear at the surface of red giants in the very late stage of stellar evolution. On the other hand, most of stars before that, including the Sun as a main-sequence star, preserve compositions provided by the previous generations of stars and supernova explosions. I will present methods to determine chemical compositions of stars and some examples of studies for understanding of nucleosynthesis in stars and supernovae and chemical evolution of the Milky Way and surrounding dwarf galaxies.
