java - Matrix Multiplication MPI not compiling -

-

im trying compile below code in jdk doesnt seem compile, getting error not statement on line 41 though is.

the line causing error is:

long endtime = system.currenttimemillis();

here code:

import mpi.*;  public class multidimmatrix {  public static final int n = 10;  public static void main (string args[]){  mpi.init(args);  long starttime = system.currenttimemillis();  int rank = mpi.comm_world.rank(); int size = mpi.comm_world.size(); int tag = 10, peer = (rank==0) ? 1:0;  if(rank == 0) { double [][] = new double [n][n];  for(int = 0; < n; i++)     for(int j = 0; j < n; j++)      a[i][j] = 10.0;  object[] sendobjectarray = new object[1]; sendobjectarray[0] = (object) a; mpi.comm_world.send(sendobjectarray, 0, 1, mpi.object, peer, tag); } else if(rank == 1){ double [][] b = new double [n][n];  for(int = 0; < n; i++) for(int j = 0; j < n; i++) b[i][j] = 0;  object[] recvobjectarray = new object[1]; mpi.comm_world.recv(recvobjectarray, 0, 1, mpi.object, peer, tag); b = (double[][]) recvobjectarray[0];  for(int = 0; < 4; i++){ for(int j = 0; j < n; i++)  long endtime = system.currenttimemillis(); system.out.print(b[i][j]+"\t"); system.out.println("\n"); system.out.println("calculated in " +                            (endtime - starttime) + " milliseconds");     }     }           mpi.finalize() ;         }       }

any appreciated!

you have

for(int j = 0; j < n; i++)

should 

for(int j = 0; j < n; i++) {

you should keep source formatted - ide's can automatically (on save or keyboard command). problem obvious after formatting.
