The research question\nfor this study is whether an abstract class offers better reusability than interface.\nThe EBSE method was followed in this thesis. Expenses of software development\ncan be reduced by reusing software code. Thesis results were that factors that promote reusability are encapsulation, loose coupling, high cohesion and inheritance.\nPoor undestandability weakens the possibility for reuse. Inheritance and composition are ways of reusing software code. Observation made in the thesis is that the\nmost significant difference between abstract class and interface is that abstract class\ncan also define implementation. Therefore if the context of use is not know very\nwell and is likely to change then interface is more safer alternative than abstract\nclass, because it does not delimit reusability in the same way as abstract class does.\nAbstract class is good when there is a need to define attributes or functionality that\nhas implementation.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Rauno R\u00e4ih\u00e4 (rahemira) on 2013-10-24 14:50:55.278937.
