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

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

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

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

Anatomy of a Program import stanford.karel.*; public class OurKarelProgram extends Karel { public void run() { move(); pickBeeper(); move(); turnLeft(); move(); This is called an import statement . It turnRight(); move(); tells Java what Karel is. putBeeper(); move(); } private void turnRight() { turnLeft(); turnLeft(); turnLeft(); } }

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