I'm having trouble with my code. I want to add a 2d array, but I get the error: ']' expected. 
  int Coor[][] = new int[10][2];
    Coor[0][0] = 1;
    Coor[0][1] = 1;
    Coor[1][0] = 2;
    Coor[1][1] = 3;
    Coor[2][0] = 4;
    Coor[2][1] = 5;
    Coor[3][0] = 6;
    Coor[3][1] = 7;
    Coor[4][0] = 8;
    Coor[4][1] = 9;
    Coor[5][0] = 10;
    Coor[5][1] = 2;
    Coor[6][0] = 3;
    Coor[6][1] = 4;
    Coor[7][0] = 5;
    Coor[7][1] = 6;
    Coor[8][0] = 7;
    Coor[8][1] = 8;
    Coor[9][0] = 9;
    Coor[9][1] = 10;
I have no idea what's wrong. If anyone knows what's wrong please help. Thanks.

There's nothing wrong with the code you posted. Where exactly do you get the error?

The error is between the 
Coor[
and 
0][0] = 1;

This should not make a difference, but maybe through greenfoot it might. Try this for the first line: 
int[][] Coor = new int[10][2];

No, still the same error.

Maybe show the entire method this code is in. If it is not in a method, then that is why you are getting the error. To define the values outside a method you should use this: 
int Coor[][] = { { 1, 1 }, { 2, 3 }, { 4, 5 }, {6, 7 }, { 8, 9 }, { 10, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 }, { 9, 10 } };

It was indeed not in a method, this fixed it, thank you!
