I New Statements:

a) if () 
   else ();
b) import element.*;
   d.lineTo(x, y)  
   	/* draw a line from the current position to (x, y) */
   d.moveTo(x, y)
   	/* move to position (x, y) */
c) DrawingWindow d = new DrawingWindow(100,100);
	/*draw in a window 100x100   */
	
	/* 
	(0,0)-----------(10,0)
	  |		   |
	  |		   |
	  |		   |
	  |		   |
	  |		   |
	(0,5)-----------(10,5)

II Working on the programming problems:

1) Draw a five-line music manuscript paper:

--------------------------------------------

--------------------------------------------
--------------------------------------------

--------------------------------------------
--------------------------------------------
--------------------------------------------
--------------------------------------------

Steps:
	a) draw one line
	b) use while statements to repeat for 5 times
	
		i) try to use for statement
			for (int i=1; i<=5; i++) {
			  <one line here>
			}
		ii) try to use while statement:
		        define a counter
		        counter = 1
		        while (counter<=5) {
		            <one line here>
		            counter = counter+1;
		        }
		        // finish
		        
		iii) repeat 8 times, using while statement.
		
2) Draw a sequence of square boxes in a line:

Steps:

	a) draw one box
	b) draw n boxes in one horizontal line
	c) draw n boxes in one vertical line
	d) draw n boxes in a diagonal line
	All use while statements to repeat the box n times by changing coordinates
	
3) Draw a sequence of square boxes in a line and each time the boxes
turn a angle

	a) turn each time a fixed angle
	b) turn each time a variable amount of angle


III Problems:

Ida does not have the access to element.*, nor element.jar.
