Need Explaination of simple matrix code?!?!?! Thx

Question

Can someone plz explain this simple code to me!?!? im a noob.
I know that this code cycles through all the rows & columns of the given
matrix, but i get completely lost at this part:
s[row][col] = m[row + theRow][col + theCol] ;
Regards,

this code takes a matrix of integers M, and a
row and column index, and returns a new matrix that is the lower
right sub-matrix of M formed from that position. The header
of the method is as follows:
public static int[][] submatrix( int[][] m, int theRow, int theCol )
int[][] s; // RESULT: the submatrix of matrix m
int sRows; // INTERMEDIATE : number of rows in s
int sCols; // INTERMEDIATE : number of columns in s
int row; // INTERMEDIATE: index for row position in s
int col; // INTERMEDIATE: index for column position in s
sRows = m.length - theRow;
sCols = m[0].length - theCol;
s = new int[sRows][sCols];
for ( row = 0; row < sRows; row = row + 1 )
for ( col = 0; col < sCols; col = col + 1 )
s[row][col] = m[row + theRow][col + theCol] ;
return s;
}

Answer 1

It copies all the values as if [theRow, theCol] were one corner of the origin of matrix.
I suggest you try running this in a debugger and then you can see what it does line by line.
