Hello

This is to announce the second shadow class for this year, hosted by SESA. Based on feedback from our various spies in your classes , we will be running through a brief overview of the basic concepts people still seem to struggle with, followed by the topics of constructors, inheritance etc.

What: 2nd Shadow Class on JAVA
When: Tuesday, 18th of March, 1pm to 2pm
Where: Engineering Lab 1.312, Level 3 - where the engineering cafe is.
Cost: FREE (members allowed only!)

Don't worry if you haven't signed up already! Come along to the class and sign up there and collect your membership card. Its $5 to sign up for the whole year.

Cheers,
SESA Exec Team

==Code from the Vehicle project==

'''Main.java'''

package vehicles;

public class Main { // This class does not need to be called "Main", it is just convenient.

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Vehicle glensBike = new Vehicle(2, "Glen");
System.out.println("Glen's bike has a " + glensBike.engineBrand +
" engine!");
glensBike.go(200);
System.out.println("Glen's bike has a mileage of " + glensBike.getMileage());
System.out.println("Glen's bike has a mileage of "
+ glensBike.getMileage());
//Add Glen as a passenger
glensBike.passengers.add("Glen");

}

}

'''Vehicle.java'''
package vehicles;

import java.util.Vector; //Required to use the Vector class

/**
* This class represents a vehicle.
* It is sweet.
* @author grob083
*
*/
public class Vehicle {

int noOfWheels; //Represents number of wheels.
String engineBrand;
private int mileage;
Vector<String> passengers; //Set to null by default.

/**
* Constructor for a Vehicle. =O
*/
public Vehicle(int wheels, String engineBrand) {
this.noOfWheels = wheels;
this.engineBrand = engineBrand;
this.mileage = 0;
this.passengers = new Vector<String>(); //Not null anymore, we can
//use it safely now.
}

public void go(int distance) {
// We use this to make our vehicle go!
//Commenting ftw!
this.mileage += Math.abs(distance);
//Math.abs() is built into Java and available automatically
}

public int getMileage() {
//returns our mileage.
return this.mileage;
}

}

'''TestVehicle.java'''
//Junit Test Class
//Conventionally named TestXXX where XXX is the class it tests.

//To get this working you will need to click on the lightbulb beside
//the error message and click "Add Junit to the build path" and
// import "TestCase".
package vehicles;

public class TestVehicle extends TestCase {
Vehicle gBike = null; //This is the bike we will be testing.

public void setUp() {
gBike = new Vehicle(2, "Glen");
}

public void tearDown() {}

public void testGlen() {
assertEquals(gBike.noOfWheels, 2);
assertTrue(true);
assertFalse(false);
}

public void testAnotherTest(){
assertEquals(gBike.engineBrand, "Yamaha"); //expect to fail

}

}

==Also Note==
We will provide time for you to ask about any problems you have been having so be sure to think of some specific questions you want to ask us.
