classloader - Uniquely identify a Java class implementation -

-

i have been dealing poorly branched projects left me dependiencies include several classes exact same qualified name. consequently, have been getting abstractmethoderror calling methods on wrong implementations. solution rename class packages worked fine.

however, wonder whether there better way - can uniquely identify java class implementation?

you can check if 2 classes (or classes of 2 objects) identical:

o1.getclass() == o2.getclass()

this expression true when classes identical (i.e. loaded same class loader).

afaik there no way determine if class @ runtime got created specific file.

-
in vs 2015, when create new mvc 6.0 application using approach: file-->new-->project-->asp.net web application-->asp.net 5 preview templates you end have following file structure on disk: artifacts src myproject.sln global.json instead if decide create blank solution first so: file-->new-->project-->other project types-->visual studio solutions-->blank solution and start adding new asp.net web application project solution; end having file structure doesn’t have global.json file , no src folder. according documentation , the global.json file used configure solution whole. includes 2 sections, projects , sdk default. the projects property designates folders contain source code solution. default project structure places source files in src folder, allowing build artifacts placed in sibling folder, making easier exclude such things source control. the sdk property specifies version of dnx (.net execution environment) visual studio...
