—————————————- Concerns and Resources: 1) Polymorphism (overloading, overriding, societal, static) 2) Serialization (steps, coding) 3) Collection (Interfaces, Groups, duplications, null away from important factors, null from beliefs, buy, synchronized) 4) a) Synchronized. b) What’s the diff. anywhere between synchronized block, and you will snychronized strategy? c) What’s the different between techniques and you will threads? 5) Exception to this rule (are, catch, ultimately, throw, puts, user-defined as well as) Sort of exception? Diff. ranging from Error and you will Different? 6) ConnectionPooling seven) Sequence (Object, LiteralPool, Means, == ) 8) Screen nine) Abstract classification (Diff. ranging from abstract category, interface), what is the usage of conceptual class, when often you utilize it? 10) Bundles 11) coffee.lang.Target (cloneable)
