Java Project (3)-discuss uidesign and javaui from the user's perspective Preface: The Hainan project was declared as completed. On the date of acceptance, the interface should be improved in addition to some code to be optimized. Teacher Mi said: even you can't help dragging down the scroll bar. Do you still expect users to use it comfortably? Epiphany: Business and functions may be the core of software, t

From the Java reflection mechanism analysis (I) API, we can see many interfaces and classes. What can we do through these interfaces? From the previous API, we can see that it can complete the following functions: 1) obtain the class A. Use getclass () (each class has this function) I. String STR = "ABC "; Ii. Class C1 = Str. getclass (); B. Use class. forname () (static method is most often used)

Don't want to be a lamb to be slaughtered!!!! To become strong ....The definition and use of functions in the front or for a reason, now the language tends to general, basic types are basically those, focus on the use of learning objects, and the most fundamental is the use of methods, so the first introduction, the purpose of the method is to reuse and encapsulationI. Definition of a methodThe definition of the method is defined using the keyword Def

Recently, an Internet project needs similar functions like other Internet projects. One of them is to display the current user's location through the IP address of the user accessing the website. Before reading the information, I first thought that there should be such a restful service, which may be free or charged. Later, I consulted the customer service staff and found a pretty good database: geoip. Chin

Recently doing something strange that requires the Java application to be able to accept user-submitted scripts and execute, the network part I chose NANOHTTPD to provide basic HTTP server support, and in Java can host many scripting languages for a long time, such as Rhino, Jython and JRuby, but they are too large, and it is difficult to implement a sandbox prot

Issue backgroundIn the previous article, the author uses the arithmetic of the super-long integers in C language, because the individual needs to use this feature in a Web project.The idea at this point is to rewrite the implementation process by using Java to rewrite the implementation of C again.Do not talk about the amount of work, just this rewriting process let me be daunting, the programmer's most headache is a bug can not find, and another is t

Anyone familiar with the Android operating system knows that the Java language is used to develop Android applications. To flexibly apply this system, you should be familiar with the various functions of the Android Java package.

Java EE -------- use filters to enable automatic user logon, secure logon, and disable automatic logon. In our life, automatic login to an account is very common, so this function is implemented using filters. This section describes how to automatically log on to and cancel Automatic Logon, and enable one-day Automatic Logon or n-day Automatic Logon. When the user's ip address is added to the blacklist, a w

: random r1 = new Random (); What needs to be explained is that when you create a random object you can give any number of valid seed numbers, the seed number is only the origin number of the random algorithm, and the interval of the generated random number has no relation. such as the following Java code: Random rand =new random (+), int i;i=rand.nextint (100); initialization 25 does not have a direct effect (note: It does not work), rand.nextint (10
