Why getResourceAsStream method is in Class class?

Why public InputStream getResourceAsStream(String name) is in Class class? It just give inputstream of file which is in jar file and there is no relation with Class class. so it can be static method and it can be in any class.

Solution

  • There is a relationship to the class:

    • The package of the class is taken into account - if you give call getResourceAsStream("baz.txt") on the class for foo.bar.SomeClass it will look for /foo/bar/baz.txt
    • The classloader is taken into account to find the resources in the first place - if it were a static method, how would it know which jar files (etc) to look in? There's more to life than the system classloader
