Show how to a class IntListArray that extends this base class and accepts only economics objects. - You may use this reference for the question ---- It is depending on the shape and structure of A: tall, square, symmetric. For each technique, give the relevant matrix equations to obtain the solution x, and point out the properties of the matrices involved. You can allude to tuple numbers in your clarification. The use demand paged virtual memory for efficiency. What problems could arise here, and how could they be overcome? [6 marks] Goat name, a string, randomly chosen from the name vector Goat color, a string, randomly chosen from the color vector Goat age, a random int between 0-7 Goat gender, a random choice between 'f' or 'm' One solution is to use ArrayList, since all Java objects extend Object. Explain why this is bad practice. [2 marks] (b) Seeking to provide a solution that allows an arbitrary set of constrained types, a programmer writes an abstract ConstrainedArray base class. To use it, the class is extended and a specialised void add(...) method should be provided for each acceptable type. public abstract class ConstrainedArray { protected ArrayList mArray = new ArrayList(); public Object get(int idx) {return mArray.get(idx);} public int size() { return mArray.size(); } } (i) Show how to a class IntListArray that extends this base class and accepts only Integer or LinkedList objects. Would it have been beneficial to use notify() instead of notifyAll() in your implementation? Justify your answer. Where appropriate, objects should be copied on insertion. [4 marks] (ii) Describe a sequence of events that would allow external modification of an object stored within an IntListArray, despite correct copying on insertion. How could this be addressed in IntListArray? [3 marks] (iii) By adding protected void add(Object o) {mArray.add(o);} to the ConstrainedArray class, the mArray field can be made private. Show how this would affect your IntListArray class and discuss the advantages of the change from protected to private. [5 marks] Assign the First host IP address from Network P subnet to Sl. c. Assign the Second host IP address from Network P subnet to PCI. d. Assign the Last host IP address from Network Q subnet to GO/1 interface of R2. e. Assign the First host IP address from Network Q subnet to S2. f. Assign the Second host IP address from Network Q subnet to PC2. g. Assign the Last host IP address from Network R subnet to G0/1 interface of R3. h. Assign the First host IP address from Network R subnet to S3. i. 17 major activities of the software design process include Software Architecture and Detailed Design. Demonstrate on how these two activities being executed? (1) Do you design software when you "write" a program? What makes software design different from coding? (2) What is the goal of software design? What would be different if developers went straight to coding without adhering to software design principles? (i3 What scheduling problem could arise here? [2 marks] (ii) How could this problem be overcome? [2 marks] (d) The designer also wishes the real-time system to that.
