Member Access in Java

I have code where a variable name is identical to the class name. I.e.:

class Foo {
  static public void main(String[] args) {
    Integer Foo;
    Foo.main(args);
  }
}

How can I call the main-method without renaming the variable or the class?

Why? The simple answer is "don't". The convention is that class names start with a capital and member variable names don't, which takes care of it completely.

use the full package name, it works.

package my.pck;
class Foo {
    static public void main(String[] args) {
        Integer Foo;
        my.pck.Foo.main(new String[] { "arg" });
    }
}

But why would you want to call main from main like that? its creating infinite loop.

If class Foo is in a package, you could use the fully qualified name:

my.package.Foo.main(args);

You could also rename variable Foo; it's bad Java style to capitalize variable names. Finally, why would you want to call main from main like that? It's going to overflow the stack very quickly.

Since Integer does not have a main(...) method, this is not a problem.
More generally speaking, if you need to disambiguate, use the full package name.

If it's not in the default package you could refer to it via the package name also, e.g.:

packagename.Foo.main(args);

or you can simply refer to main without the class name, e.g.:

main(args);
