How do I do this?|

Hi dudes, I'm wondering about how I can do something like this in java

func(){print "hi"}
func2(){print " there"}

tab[] funcs = {"func", "func2"}
for(int i = 0; i < 2; i++){
funcs[i]()}

resulting in "hi there"

I think this is called anonymous functions in some other codans.

>>1-2
How are they functions if they have side effects?
