Generally speaking feel can accept, the teacher said the book content can understand understand, class homework These can also be completed independently, although do when still a little rusty but fortunately can find a way to solve in time. In the future study must keep in mind the teacher's teaching more thinking more practice, independent completion of homew

The book is generally finished, but the seventh chapter is not in a hurry to end.But fortunately it is finished, barely count it.Recall this year, quite feeling, the heart has been seeking progress, but it is very difficult to act up.Think about it indeed ah, want to always progress must sacrifice their spare time, although not to exclude learning, but you have to admit that the feeling of paralysis is very good.Man, there's really nothing to stop, an

still need to read first, in reverse summarize the following, the effect will be very good, the first chapter has a lot of not written up, such as Java object Heap mechanism, look at Java before the best C, C + + Some understanding, Java did optimize a lot of features, but I am not a particular language of the death of loyalty, arguing this also meaningless , bu

Learning programming language at school is just plain understanding, there are a lot of things that do not understand, want to pass this book to the Java language has a deeper understanding, for future study and work will have great benefits. Rather than a cursory look at some of your books, know it but do not know why, this is not what I want to learn.The readin

The 2nd Chapter: everything is the object If a member of a class is a basic data type, Java ensures that it obtains a default value even if it is not initialized. For a "local" variable (that is, a field that is not a category), a value must be given before use, and if you forget to do so, Java will return an error at compile time to tell you that the variable is not initialized. A is an object, and

SetSelected (false);} else if (c instanceof jcombo

During the Spring Festival read the next "java:the complete Reference" found this writing in simple, I think a question, the book a lot of content we also know, but why we can not write such a book, so comprehensive, so systematic, so simple and easy to understand. Have to admire Herbert Schildt programming skills, need to mention is Herbert Schildt wrote a lot o

Java 8 brings a lot of features that can make coding more concise. For example, like the following code: Collections.sort (Transactions, new comparator Can be replaced with the following more compact code, the same functionality, but read up with the problem statement itself closer: Transactions.sort (Comparing (Transaction::getvalue)); The main features introduced in

generics, also known as parameterized types, are used when defining classes, interfaces, and methods by indicating the type of object to be processed by the type parameter, which can be reused by many different types of objectsgeneric programming is implemented using inheritance before adding generic classes in Java. For type parameters, this code might be useful for all of the built-in classes, and the typ

With the help of bestselling author Herbert Schildt (Schmidt), you can start learning the basics of Java programming immediate

provide a static or dynamic local package, and the directory where the local library resides is available through the JRE attribute "Java.library.path", which generally contains all the directories in the PATH environment variable but is not required.Java does not introduce a local library at compile time, but if it is not set correctly, it will error "Java.lang.UnsatisfiedLinkError:no xxx in Java.library.path" at run time. You can include a local library like this: Copy the local li

tool programming languages, tools, and methodologies. That's why we want to accumulate as much experience as possible and use as many languages and frameworks. Focus on the basics of programming, because the basics never change: Focus more on architecture than programming. If you think there is only one right way to do things, then it may be time to test the act

methods.　　② down transformation and runtime type recognitionAs the upward transformation loses the specific type information, we think that by going down the transformation should be able to get type information, in the Java language, all transformations will be checked. If the type does not match, a classcastexceptionis returned. This behavior of checking the type during run is called Runtime type recognition (RTTI).5. Summary Polymorphism means "di

the classes and methods that are loaded is in the method Area. The constant pool is filled with objects of the basic type wrapper class such as Integer.Byte.Short. and the string that Appears.Each time the new object is allocated to the object, it is assigned to a header address in the heap memory. Each time you use the method, the memory is opened in the stack memory to use. the pointer and use of the variable in the Method. when the method ends, the stack memory is closed at any Time.The JVM
