use the keyword extends2, can use the symbol to give a number of limits3, if there is a limit to the existing interface and class, then the class must be only one, and placed in the first placeAfter practicing the annotation of the sample program, I helped me understand the knowledge of the generic class better, but the knowledge of the inheritance rules of the generic type is a little vague, it will seek help in the book and blog Park, and other tools can help us to solve the problem of learn

). Flexibility. The basic data type data can be encapsulated into a wrapper object of that data type. 2 (1). The collection class holds objects that are instances of the object class, and once an object is placed in the collection class, its class information is lost, which is intended to be universal (2) of the collection class. The Objectl class is a superclass of all collection classes and can be generic, but re-sculpt. This is a common interface in the collection framework:Where collection i

: C language input with scanf, output with printf. Java input with scanner, output System.out.Chapter Fourth Class and ObjectThe class body contains the instance domain and the method two parts, this method is the same nature as the function in C language. The In-class methods have access to the instance domain, so that secure access to the data is achieved through encapsulation. An object contains three parts: The behavior of an object, the state of

The inner class is used only by his outer-nested class, and other classes cannot declare an object with the inner class of a class. Inner classes can be decorated as static inner classes. The static inner class

20172333 2017-2018-2 "Java Programming" 10th Week study SummaryTextbook Learning Content13th Chapter A collection is an object, a database that holds other objects. Collections can hold different kinds of objects and can hold objects of the same type, which are divided into heterogeneous and isomorphic. Generics are a feature of programming languages. Allows programmers to define variable p

Java Nineth Week learning experienceThrough this week's study, learned the exception assertion and the log, has learnt to enable the assertion in the Eclipse compiler, but, regarding the exception, in the shorter teacher teaches the instance the procedure to be able to catch the exception, but in the Long program task Seven task Eight does not know is what kind of exception, No exception catch exception should be added, task nine does not define the L

non-static fields of the current object to the new object, whether the field is a value type or a reference type. These two copies are called Light and deep copies, respectively. in my opinion, the dead point of a shallow copy is that the original object and its copy refer to the same object, while a deep copy keeps them from pointing to the same object. Overall, this week's study is very rewarding, but in the experiment still encountered a lot of difficulties, interface settings, sub-class fun

Java Learning Week 13ththis week, the first six chapters of the knowledge point of the small test, in the test I also found a lot of their own learning on the hidden dangers, some knowledge points to understand too rough, not very good to remember those important small details, the attention to the program run, the algorithm design, but ignored the very important basic knowledge of memory , it is very dangerous, only a good understanding, master the b
