java - Can't find or load main class -

-

for reason getting error saying can not find or load main class, can give me reason this?

package findfile;  import java.io.file;  /**  *  * @author kevin  */ public class findfile {     public void listfilesandfolders(string directoryname)     {         file directory = new file(directoryname);                file[] flist = directory.listfiles();          (file file : flist)         {             system.out.println(file.getname());         }     }      public void listfiles(string directoryname)     {         file directory = new file(directoryname);         file[] flist = directory.listfiles();          (file file : flist)         {             if (file.isfile())             {                 system.out.println(file.getname());             }         }     }      public void listfolders(string directoryname)     {         file directory = new file(directoryname);         file[] flist = directory.listfiles();          for(file file : flist)         {             if (file.isdirectory())             {                 system.out.println(file.getname());             }         }     }      public void listfilesandfilessubdirectories(string directoryname)     {         file directory = new file(directoryname);         file[] flist = directory.listfiles();          (file file : flist)         {             if (file.isfile())             {                 system.out.println(file.getabsolutepath());             } else if (file.isdirectory())             {                 listfilesandfilessubdirectories(file.getabsolutepath());             }         }     }      public static void main(string[] args)     {         findfile findfile = new findfile();         final string directorywindows = "c:\\test";          findfile.listfiles(directorywindows);      } }

your class fine, think "ide" (textpad ?) not seem manage compilation , running of java programs.

just @ location compiler writes class file, should like:

findfile/findfile.class

just go directory directory findfile is, open command line window , run class this:

java findfile.findfile

i suggest use real ide, eclipse instance 1 java developing.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
