1. Declare 2-D array, aArray, and write statements 
	to store the following data -

	1 	2
	11	22
	

A.	int[][] aArray = new int[2][2];

	aArray[0][0] = 1;
	aArray[0][1] = 2;
	aArray[1][0] = 11;
	aArray[1][1] = 22;

2. Out the elements of 2-D array to the monitor, in the format
	of above table.
	
	for(int row=0; row<2; row++)
	{
		for(int col=0; col<2; col++)
			System.out.print(aArray[row][col] + " ");
		System.out.println();
	}
	
	

3. Selection sort to ascending by hand for the following list. 
	How many passes needed? _5_
	

	[12]	7	16	11	(6)	9
	
	6	([7])	16	11	12	9
	
	6	7	[16]	11	12	(9)
	
	6	7	9	([11])	12	16

	6	7	9	11	([12])	16
	
	6	7	9	11	12	16


4. 1-D array. Declare an array, oneArray, with 20 floating numbers.

	double[] oneArray = new double[20];

5. Write statements to store the first element with 3.14, and the last
	one with 9.65.
	
	oneArray[0] = 3.14;
	oneArray[19] = 9.65;

6. Out all the elements of the array to the monitor in a row.

	for(int i=0; i<20; i++)
		System.out.print(oneArray[i] + " ");
	System.out.println();
	

7. Assuming a file has more than 50 real numbers, store its first 20
	to the above array?

	Scanner kb = new Scanner(System.in);
	
	for(int i=0; i<20; i++)
		oneArray[i] = kb.nextDouble();


// P.494
