technologies, there is no need to download plugins or small programs.Ajax has a lot of merit, and it is these strengths that reflect its shortcomings (of course, the shortcomings can be overcome).Disadvantages:1. Security issues2. Support for search engines is relatively weak.3. The exception handling mechanism of the program is broken.4. The original intention of URL and resource location is violated.Actual combata simple, but useful example: TheJava version asynchronously verifies that userna

is better to reuse objects instead of creating new objects of the same functionality every time you need them.In addition to reusing immutable objects, you can reuse mutable objects that are known not to be modified.To use the basic data type, try not to use the corresponding encapsulation class.6th: Elimination of expired object referencesYou can't think of a garbage collection mechanism, so you don't have to think about memory management.For exampl

10 Big building tools common to Java programmers Recently, I did a programmer-developed survey of 20 big data tools used by Java programmers. Recently I did a Java survey and asked a lot of developers about what tools/frameworks they used over the last 12 months. Respondents

15, because of 1+2+3+4+5=4+5+6=7+8=15, so the result prints out 3 sequential sequence 1--5,4--6,7--8.With previous experience, we also consider using two tree small and big to represent the minimum and maximum values of the sequence respectively. First initialize the small to 1,big to 2. If the sequence from small to big and greater than s, we can remove the sma

allows you to modify instead of creating a new object for each different string. Also, the conversion of these two kinds of objects is very easy.At the same time, we can also know that if you want to use the same content string, you do not have to new a string each time. For example, we want to initialize a string reference variable named S in the constructor, set it to the initial value, and should do this:public class Demo {Private String S;...Public Demo {s = "Initial Value";}...}Rather than

the topic is to ask for the smallest number of k numbers from a large amount of data, because the size of the memory is limited, it may not be able to load these massive data into memory all at once. At this time, we can assist storage space (such as disk) to read a number each time, according to Getleastnumbers way to determine whether it is necessary to put the container leastnumbers. This approach only requires memory to accommodate leastnumbers. So it fits the case that n is
