The D$$0\atop{J}$$ is a family of four orbitally excited mesons: D$$*\atop{2}$$(2460)⁰, D₁(2420)⁰, D₁(j = 1/2)^-, and D$$*\atop{0}$$(j = 1/2)⁰. This dissertation presents the measurements of the inclusive branching fractions, β(B^- → D^*+π^-π^-) and β(B^- → D⁺π^-π^-). The D$$0\atop{J}$$ provides an intermediate resonance for those two modes. The data used for this analysis consists of Runs 1-5 with total integrated luminosity of 343.38 fb^-1, which is corresponding to 383.92 million B$$\bar{B}$$ pairs, provided by the BABAR detector at the PEP-II asymmetric B Factory. The values presented are: β(B^- → D⁺π^-π^-) = (1.12 ± 0.02 ± 0.08) x 10^-3; β(B^- → D^*+π^-π^-) = (1.67 ± 0.03 ± 0.13) x 10^-3.
