Maximum value of column in matrix?

How can i find the maximum value of a column in a matrix using only 2 for's in Java?

for(int i = 1; i< N; i++)
    for(int j = 1; j < M; j++)
         i want to find the maxim for each column

public int findMaxInCol(int colIndex){
  int max = Integer.Min;
  for(int row=0;row<Matrix.Rows;row++){

    if(matrix[row][colIndex] > max){
       max = matrix[row]colIndex];
   }

}
   return max;
}



void int findMaxOfMaxes() {
   int maxOfMaxs = Integer.min;
   for(int col=0;col<j;col++){
      int maxInCol = findMaxInCol(col);
      if( maxInCol > maxOfMaxs)
          maxOfMaxs = maxInCol;
    }
    return maxOfMaxs 

}

//pseudocode

//editing after finding that you wanted max in a matrix. You are right, you need 2 for loops.
