Extract methods across classes? [message #335673]

If I have something like this:

public void myMethod() {

System.out.println("Hello);
int y = 1;

for (int i = 0; i <= 99; i++) {
System.out.println("i = " + i);
}

y++;

for (int i = 0; i <= 99; i++) {
System.out.println("i = " + i);
}

}

and I highlight the first for loop and command it to extract into a
method, it will recognize that the 2nd for loop is the same and replace it
with a call to the new method, in addition of a call at the place of the
first for loop.

My question is, can it do this across methods? across classes?

It works but only inside one compilation unit.

Thanks for your reply.
IntelliJ can do this across classes.
Something for the Eclipse team to consider, if they are not already doing
so.
