                  问题描述

                  我想要一个 2d 矩阵向右旋转,它编译得很好,但是当我尝试运行时,它说 数组索引超出范围异常.例如,我希望 {{10,20,30},{40,50,60}} 旋转成 {{40,10},{50,20},{60,30}}:

                  I want a 2d matrix to rotate to the right, it compiles fine but when I try to the run it says that the array index is out of bounds exception. For example, I want {{10,20,30},{40,50,60}} to rotate into {{40,10},{50,20},{60,30}}:

                  public static int[][] rotate(int[][] m) {
                      int[][] rotateM = new int[m[0].length][m.length];
                      for (int i = 0; i < m.length; i++) {
                          for (int j = 0; j < m[0].length; j++) {
                              rotateM[i][j] = m[j][m.length - i - 1];
                          }
                      }
                      return rotateM;
                  }
                  

                  public static void main(String[] args) {
                      int[][] m = {
                              {10, 20, 30},
                              {40, 50, 60}};
                      System.out.println(Arrays.toString(rotate(m)));
                  }
                  

                  推荐答案

                  这是一个工作示例:

                  private int[][] rotateMatrix(int[][] matrix) {
                      int backupH = h;
                      int backupW = w;
                      w = backupH;
                      h = backupW;
                      int[][] ret = new int[h][w];
                      for (int i = 0; i < h; ++i) {
                          for (int j = 0; j < w; ++j) {
                              ret[i][j] = matrix[w - j - 1][i];
                          }
                      }
                      return ret;
                  }
                  

                  我使用此代码在俄罗斯方块中旋转我的积木.此代码顺时针旋转矩阵.

                  I used this code to rotate my bricks in Tetris. This code rotates the matrix clockwise.
