,(Facts stolen from) MC and open questions
Primitive vs reference
Primitive Reference

Can not be null Can be null

Store the actual values Store the addresses

int/double/boolean/char/short/float/long/byte object/String/array


Compilation vs runtime errors
Compilation error Runtime error

Will prevent the program from running Will prevent the program from executing

Syntax/semantics Exceptions noticed while running program

Like too many/missing { } + forgetting ; + Like division by 0 (ArithmeticException) +
using a value without declaration NullPointerException


Inheritance
- In Java all classes inherit from the Object class directly or
indirectly. The Object class is root of all classes.
- Multiple inheritance is not allowed in Java.
- A non-abstract child class must override an abstract
method inherited from its parent by defining a method with
the same signature.
- Child classes can override and overload methods defined
in their superclass(es).
- A non-abstract class can not contain abstract methods.

Arrays
- An array is an arrangement of consecutive memory
locations.
- Using an array can lead to an
ArrayIndexOutOfBoundsException.
- An array does not grow automatically when you add elements to it.
- If you pass an array as a parameter, the memory address of that array is copied
rather than the values that are stored in the array.

, Array copies




What will happen if we run the main method?
The program will print true

Class design
1
- There is a non-abstract class Vehicle.
- BMW is a carmaker brand.
- There is more than 1 carmaker brand.
- Every BMW is a Vehicle.
Which of the following design choices is most appropriate?

x You should create a class BMW that inherits from Vehicle.
✓ The Vehicle class should have an attribute indicating the brand.
x There should be a “1 to 1” relationship between Vehicle and BMW.
x There should be a “1 to n” relationship between Vehicle and BMW.
