the parent class to the type of the child class. In the parent class, if the abstract method is defined, the parent class must also be decorated with an abstract, and if the child class defines all the abstract methods in the parent class, the subclass may not be an abstract class. Conversely, subclasses are abstract classes. An abstract class can contain specific data and methods, or it can contain no abstract methods. By using a method name in a super.+ parent class in a subclass, you can cal

This week the teacher according to the traditional teaching method: the classroom teaching method to the fifth chapter succession carries on the key explanation, through the teacher's explanation, I learned a lot of knowledge, especially some details, this is oneself in the self-study process not to notice. This week, the teacher slowed down the progress, I feel that the effect of learning is much better than the previous weeks, may also be many years of teacher classroom teaching method down th

: The difficulty they encountered was that they would encounter code that they did not understand and were worried that they could not catch up with the development process.The remaining two groups I get the same information as the above two groups, for the problems encountered are some development of the above problems. Interactive reflection: I feel that this time and the previous interaction is too hasty and too careless, many groups of my (Mo Lizhong) came to express do

this week learned about exceptions and assertions. Exceptions are divided into internal (set) exceptions and create class exceptions (custom exceptions), while run-time exceptions (such as stack null) are unchecked exceptions, that is, non-checked exceptions, non-runtime exceptions are check exceptions, which are checked for exceptions.All exceptions are inherited by Throwable and are broken down into error and exception.When an exception is thrown, a method may throw multiple checked exception

This week we learned about generic programming, which allows us to write code that is reused by many different types of objects. A generic class is a class that has one or more type variables. We can define generic classes, or we can define generic methods, which can be defined in ordinary classes and generic methods. The invocation of a generic method is to put a specific type in the angle brackets before the method name.Type variables are qualified, Wildcard characters are not type variables,

This week we have analyzed the previous procedures and learned the contents of the Nineth chapter of the collection.The next step is to strengthen the review of the knowledge we have learned, and it is also an adjustment to deepenThe process.We mainly master vector, Stack, Hashtable three classes, in the learning process moreIn-depth mastery of the ArrayList class. ArrayList implements an array that is variable in size andCan be accessed like a linked list. It provides functionality similar to t

In this week's study, lambda expressions, anonymous inner classes, and local inner classes have their own understanding. They are used in callback techniques to reduce the amount of code compared to previous callbacks. This programming task has played a role in reviewing the previous knowledge. Discover the knowledge that you have not mastered before. In a program that sorts names in an identity card, the result is wrong if only arrays.sort () is used to sort the array of strings that consist of

What is the price of Java training in Chengdu in 2017? How much will it cost to enroll? This is based on the class decision, that is, Java short class, short-term classes are generally about 4-6 months, so the cost will be a little different, half the cost of 10,008 up and down.Now Java training belongs to high-end pro
