实现了排列组合算法的类（JAVA）,实现了排列组合算法的类（JAVA）-Permutation and combination to achieve the type of algorithm (JAVA), the realization of the permutation and combination of types of algorithm (JAVA)

一些很经典的算法！！！包括八皇后问题和背包问题，排列组合问题和数字拆分问题等.-Algorithm for some very classic! ! ! Including the eight queens problem and the knapsack problem, permutation and combination problems and digital split issues.
