Using bitwise OR 0 to floor a number

Why is Git better than Subversion?

svn checkout svn://foo.com/bar bar
cd bar
# edit
svn commit -m "foo"
and
git clone git@github.com:foo/bar.git
cd bar
# edit
git commit -a -m "foo"
git push
Where Git really shines is branching and working with other people.

Create list of single item repeated N times
... change one of them, they all change because they're all the same object:
foo = [[]] * 4
foo[0].append('x')
foo now returns:
[['x'], ['x'], ['x'], ['x']]
But with immutable objects, you can make it work because you change the reference, not the object:
>>> l = [0] * 4
>>> l[...

Does a method's signature in Java include its return type?
....
Since the question was edited to include this example:
public class Foo {
public int myMethod(int param) {}
public char myMethod(int param) {}
}
No, the compiler won't know the difference, as their signature: myMethod(int param) is the same. The second line:
public char myMeth...
