The IDE I'm using is idea, and the places where eclipse may be set up are different1. Encoding of source filesWhen writing. java files in various Ides, there is an encoding that the IDE stores files on the machine in this encoding format, such as my settings, to set the S.java file to GBK format2. At compile time, Javac will read the file in the specified encoding format and then compile it into Unicode format.For example, I joined encoding GBK this s

3 Kinds of sortingTreeSet java.lang.Comparable interface in the class List Collections.sort (list): You need to implement the comparable interface and override the Tocompare () method. Collections.sort (list,new Comparator () {@Override public int compare (object o01, Object o02) ...}); Object classes do not implement interfaces. 2 Methods of reverse outputCollections Tool Reverse Output element: Collections.sort (list, Collections.reverseorder ()); Descending arrange

No master list or error:invalid or corrupt jarfile Xx.jar in Xx.jar 　　This problem is encountered because your jar package does not have a portal set for the main class. 　　That is, Main-class:packagename.classname is not defined in the MANIFEST.MF file of the Meta-inf folder(here Main-class: with Packagename.classname A space and a newline character at the end of the line) 　　We can open your export jar with WinRAR (do not unzip), find the Manifest.mf file in the Meta-inf folder,
