Great team!... Some of them were in your place just 2 years ago

Stanford? Language Call me Tyler I grew up in Arizona. Played a lot of soccer growing up. Really liked math/science.

Stanford I’m a graduate student in Electrical Engineering at Stanford How much experience did I have when I first did this material? It was difficult for me too. Started teaching in section leading program. Now I coordinate that program. We want all of you to be successful That’s why we have such a large course staff But over years and years and years we have been working on our material so that everyone gets through… Not competing against anyone but yourself. Everyone can win!

Logistics Schedule is fluid Explain purpose of lab/section. Learn by doing!!

Prerequisites Just need to know how to turn on a computer and ask for help. We love questions!!!

Very High Level We will teach some specific things (Java syntax, Karel commands) but more importantly… We teach software engineering principles. Much larger than just programming. Mechanics of the language are nothing compared to the principles. You are going to learn the principles by programming in Java

Breakout demo!

What if I fall behind? First, it is okay! Everyone learns at a different pace. Ask for help.

Anatomy of a Program import stanford.karel.*; public class OurKarelProgram extends Karel { public void run() { move(); pickBeeper(); turnLeft(); turnRight(); putBeeper(); } private void turnRight() {

This is the program's source code Anatomy of a Program import stanford.karel.*; public class OurKarelProgram extends Karel { public void run() { move(); pickBeeper(); turnLeft(); turnRight(); putBeeper(); } private void turnRight() { This is the program's source code

This piece of the program's source code is called a method.

This line of code gives the name of the method Anatomy of a Program import stanford.karel.*; public class OurKarelProgram extends Karel { public void run() { move(); pickBeeper(); turnLeft(); turnRight(); putBeeper(); } private void turnRight() { This line of code gives the name of the method (here, run)

This is called an import statement. It tells Java what Karel is.

For Loop for(int i = 0; i < N; i++) { // to repeat N times }

Review for(int i = 0; i < N; i++) { // to repeat N times }
