Learning

	Learning is a pull not a push.
	Learning takes effort
	Learning complex subjects requires dedicated brainpower

Strategies for learning

	Learn from an expert.
	- take a class
	- read the book they wrote.

Books are your friend.

	Typical website on HTML – 10 pages.
	Typical book on HTML – 200 pages.
		Indexed
		Ordered from basics to more complex stuff.

Reading for learning

	Read a section to start setting up a mental  framework.
	Try to use what you read.
	Read it again!
	Read a different book

Programming is a skill

	Learn by watching others
		Read the code they wrote
	Start with the basics
		- don’t jump in the deep end.
	Practice makes perfect

More on if.

	if (x > 3) ;
	g.drawString("x is too big", 50, 50);

; is empty statement.

	// if (x>3) don’t do anything
	if (x > 3) ;   // we don’t want this semicolon!
	// always write "x is too big"
	g.drawString("x is too big", 50, 50);

; = end

	// this is correct
	if (x > 3)
	g.drawString("x is too big", 50, 50);
	// using curly braces is safer
	if (x > 3) {
	g.drawString("x is too big", 50, 50);
	}

infinite loop

	// Loop forever because we never get
	// to the statement that changes x.
	while (x < 3) ;
	x = x +1;

Reformat code to see problems

	Remember the compiler ignores all white space, so indentation is a convenience for us.
	while (x < 3) ;
	x = x +1;
	if (x > 3) ;
	g.drawString("x is too big", 100, 100);

While loop

	int counter = 0, x = 10;
	while ( counter < 8 ) {
	g.drawString("*", x, 20);
	x = x + 10;
	counter++;    // counter = counter + 1
	}

While loop

	int counter = 0, x = 10;
	while ( counter < 8 ) {
	g.drawString("*", x, 20);
	x = x + 10;
	counter++;    // counter = counter + 1
	}
