Source code analysis of the collections list of Java Collection SeriesI. Introduction to tranquility list A sort list is an ordered sequence that allows efficient insert and remove operations at any location. It is implemented based on a two-way linked list. Ps: Here is a question about whether or not the data structure of the sorted list is a circular two-way li

Maybe we often pay attention to the characteristics of each Set in practical applications or interviews. For example, the Set cannot store duplicate elements, and cannot maintain the insertion and size order, map sets store key-value pairs and so on. However, if you want to learn Java well or have a higher goal and be proficient in Java, it is far from enough. In fact, we still need to know more about the c

According to the previous article's configuration, Servicetask has been able to invoke WebService with @webparam and @webresult releases, but how to invoke the webservice of these publications without these parameters, Because other languages do not @webparam these parameters, consider the following example:Counter.javaAfter publishing, the WSDL file is as follows (key content):We will find that the first parameter name of the Prettyprintcounttwo method defaults to arg0, and the second parameter

Java exception encapsulation (custom error codes and descriptions, with source code) Only when I really work can I find that exceptions in Java are still very common in real work. You must know when to throw an exception. Of course, all the exceptions actively thrown during the real work are sub-installed. You can defi

Java-source code analysis Today, when I checked the source code of the listing list, I encountered a pitfall. When I studied the source code, I found that the shortlist is a linear link

Premise:When using Scala's Sortwith, discover:def sortwith (LT: (A, a) ? Boolean): List[a] //A is a list element typeSort by the specified comparison function LT, and the ordering is stable,Ultimately, essentially, the call to Java.util.Arrays.sort is ordered.Eg: List(1,-3, 4, 2, 6) Sortwith (_ Therefore, to go to understand the method of Java.util.Arrays.sort, online cleaning, see the following write good, moved here for study.　Sorting for all types is available in

congruential (Congruential method) is a very common method of generating random numbers, which is used in many programming languages, the most obvious is Java, and Java.util.Random class is one of the congruence method--linear with congruential (Linear Congruential method), in addition to the multiply with congruential (multiplicative congruential method) and mixed with congruential (Mixed congruential method). OK, now let's open the
