G6021: Comparative Programming Exercise Sheet 9 A: Logic Programming We will implement a small fragment of a logic programming language. First we explain the language. Programs are collections of: • facts: things that are known to be true, • and rules: ways to generate new facts. In addition, we have a query which is a

Comparative Programming: 2020 Paper 1. (a) Define multiple inheritance and state any problems associated with this concept. Briefly show how these problems can be circumvented, using examples to support your argu- ment. [10 marks] (b) • Solution notes: The example should exhibit name clashes (a simple example will suffice). Possible solutions: • Implicit resolution, defined
SOFT2201/COMP9201 Week 2 Tutorial OO Theory in Java Inheritance Classes Classes are a fundamental construct within java, they allow the programmer to aggregate data and functionality under a defined type. This feature isn’t just for reusability and simplicity, we are able to safely read and write to memory by ensuring we adhere to the type

Defined by the mathematician Alonzo Church in the 1930’s, as a precise notation for anonymous functions. He noticed that an expression x +
SOFT2201/COMP9201 Tutorial 6 Behavioural Design Patterns 1 Behavioural Design Patterns 1 Behavioural patterns allows you to encode behaviour within objects to be executed at run time. Be- havioural patterns like State and Strategy patterns allow the programmer to utilise input at runtime to change the object’s behaviours. Strategy Pattern One thing to note is that
