get a runtime error called an EX Ception.Downcasting and the runtime checks require extra time for the running program and extra effort from the programmer.The solution is called a parameterized type mechanism. (Java se5,called generics)A parameterized type (compiler-level technology) is a class, the compiler can automatically customize to work with particular Types.Object Creation LifetimeWhen to destroy object?C + + takes the approach that control

(This also applies to private methods, which is automatically final.)Convariant return typesJava SE5 adds convariant return types, which means, a overridden method in a derived class can return a type derived From the type returned by the Base-class methodDesigning with InheritanceIf you choose inheritance First when you ' re using a existing class to make a new class, things can become needlessly comp Licated.A better appro

, they all provide the same interface to the compiler. The Java compiler generates platform-independent bytecode that cannot be run directly on different platforms and must be run through an intermediary converter (JVM).First the Java compiler generates the code that the virtual machine understands (platform-independent bytecode files), and then the VM interprets the code to execute.The JVM is a key part of

way to impose constraints on multiple parameters is to check all the parameters that a constraint must hold with multiple setter methods. Once an invalid argument is passed, the constraint fails immediately, rather than waiting for the build method to be called. The slight advantage of builder compared to constructors is that builder can have multiple mutable parameters. Constructors, like methods, can have only one mutable parameter.The traditional abstract factory implementation in

circumstances to 8 screen around to display. This makes it difficult to read a program or modify a program. It is therefore advisable to extract the block that completes the comparison of independent functions as a single function. A block that accomplishes the same or similar function is extracted independently of a sub-function. It can be found that the simpler the upper-level function is, the more specific work is done by invoking a few sub-functions, the more the underlying function complet

Never start learning from IDE tools (JBuilder, Eclipse, and NetBeans), the

example:What exactly is boxing and unpacking, boxing is that the compiler performs a boxing operation after the underlying type is changed to the corresponding object type, and the reverse is the case.
