Java中二维数组矩阵运算如何实现，求解答。

Answer 1

package answear;

public class Inter {
 
 public static void main(String[] args) {
  int[][] a = {{2,3,4},{4,6,8}};
  int[][] b = {{1,5,2,8},{5,9,10,-3},{2,7,-5,-18}};
  int[][] c = new int[2][4];

 System.out.println("生成的新数组c是：");
  for(int i=0; i<2; i++){
   for(int j=0; j<4; j++){
    int temp = 0;
    for(int k=0; k<3; k++){
     temp += a[i][k]*b[k][j];
    }
    c[i][j] = temp;
    System.out.print(c[i][j]+" ");
   }
   System.out.println();
  }
 }
}
