java - What does each element do ("(.)\\1{1,}", "$1") in this code? -

- 

  आयात करें java.util.Scanner; पब्लिक क्लास रेडिएजेज {सार्वजनिक स्टेटिक व्हाइड मेन (स्ट्रिंग एजीआर []) {स्कैनर स्कैन = न्यू स्कैनर (सिस्टम।); System.out.println ("इनपुट पाठ!"); स्ट्रिंग teksts = scan.nextLine (); System.out.println ("परिवर्तन के बाद पाठ!"); System.out.println (teksts.replaceAll ("(।) \\ 1 {1,}", "$ 1")); }}

यह समान अक्षर के अनुक्रमों से मेल खाता है और उन्हें केवल एक ही घटना में गिर जाता है। / P>

उदाहरण: "aaaaabcccdd" -> "abcd"

c++ - Cmake produces file extensions in static library archives -

-
I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

c# - XML - Serialize class - Some questions -

-
I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content. Then this kind of structure: file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file. Now the content may look something like this: Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this: And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it. I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now,...
