I needed to recap my Java knowledge recently. Here are snippets of a very basic example I wrote re-familiarise myself with Java.
Inheritance: The extends keyword is used:class Car extends MotorVehicle { }Constructors: Which constructor is used depends on the argument to the constructor:
MotorVehicle (String mType){ this.mType=mType; } MotorVehicle (){ }Overriding: overriding a method:
@Override public String toString() { return mType + " " + maxSpeed;Collections: A basic example of using a vector to store objects and retrieve:
Vectormvs = new Vector (5); mvs.addElement(mv1); mvs.addElement(mv2); for (int i = 0;i < mvs.size();i++) { System.out.println(mvs.get(i)); }
