为什么这个矩阵乘法不能运行?
源代码如下   :
improt   java.io.*;
public   class   MultiMatrix   {
  int[][]   multiplyMatrix;
  public   static   void   main(String   args[]){
  int[][]   a={{1,0,3,-1},{2,1,0,2}};
  int[][]   b={{4,1,0},{-1,1,3},{2,0,1},{1,3,4}};
  MultiMatrix   mm=new   MultiMatrix();
        mm.mMatrix(a,b);
  mm.display();
  
  }
  public   void   mMatrix(int[][]   a,int[][]   b){
  multiplyMatrix=new   int[a.length][b[0].length];
  for   (int   i   =   0;   i <a.length;   i++)   {//rows   of   a
  for   (int   j   =   0;   j <b[0].length;   j++)   {//columns   of   b
  for   (int   k   =   0;   k <a[0].length;   k++)   {//columns   of   a   =   rows   of   b
  multiplyMatrix[i][j]=multiplyMatrix[i][j]+a[i][k]*b[k][j];
  }
  }
  }
  }
  public   void   display(){
  for   (int   i   =   0;   i <multiplyMatrix.length;   i++)   {
  for   (int   j   =   0;   j <multiplyMatrix[0].length;   j++)   {
  System.out.print   (multiplyMatrix[i][j]+ "   ");
  
  }
  System.out.println   ( " ");
  }
  }
  }    
 

出错信息是Exception   in   thread   "main() "   java.lang.NoClassDefFoundEerror:MultiMatrix.java
请教高手帮我解决下,急用?

------解决方案--------------------
Are you trying to execute your program like this?
java MultiMatrix.java

This is wrong. Use the main class name as the argument of java command.
java MultiMatrix

------解决方案--------------------
同 z_lping(Schemer) 能编译,能运行
你用什么环境的?

把类名MultiMatrix改成MultiMatrixy就可以了,试试看
