For the instance field and the constructor in Table2dMxSumRowCol.java
============================================================================

(1) The instance field of a Table2dMxSumRowCol object: 

	private int[][] nums; //This instance field is a reference to refer to the 2D array 

	
(2) Create the 2D array in the constructor:

	nums = new int[10][10]; 


(3) Construct the scanner object for file reading
    The argument for Scanner constructor is a File object
    The argument for File constructor is input as the filepathname 

		inFile = new Scanner(_________); //replace the blank with: new File(filepathname)
		
		
(4) Read file until the end (as long as there is data remaining)
		while (___________) //replace the blank with: inFile.hasNext()
		{
			int row, col, value;
			row = inFile.nextInt();
			col = __________________
			value = __________________
			nums[____][____] = ____; //Note: should be [row][col], do not change the order
		}

		
==============================================
For print() in Table2dMxSumRowCol.java
==============================================
	public void print() {

		/* For each row, we print the columns in that row.

		   Note: row and column are easily mixed up.
			To avoid careless mistake, readability is important.
			Use meaningful variable names like row,col or r,c, or y,x etc. 
			Do not use i,j. 
		*/

		for (int row=0; row<10; row++) 
		{
			for (int col=0; col<10; col++)
			{
				System.out.print("\t"+nums[row][col]); //separated by tabs
			}
			System.out.println();
		}
	}	


==============================================
For getRowSumMax() in Table2dMxSumRowCol.java
==============================================
	//Return the maximum sum among the rows
	public int getRowSumMax(){
		//Your task: implement this method
		
		return 0; //This is temporary!!  You may finish this method in next step.
	}
