There is no Java equivalent.
Here is a bit of a contrived example:

def mygen(n):
x = 0
while x < n:
x = x + 1
if x % 3 == 0:
yield x
for a in mygen(100):

Make this an alias
Since it's a bit long, you might want to add an alias to your .zshrc or .bashrc. Mine is called gbpurge (for git branches purge):
alias gbpurge='git branch --merged | grep -Ev "(\*|master|develop|staging)" | xargs -n 1 git branch -d'

Anonymous recursive PHP functions
... f x = f (Y f) x.

{
return function() use ( $func )
{
$args = func_get_args();
array_unshift( $args, fix($func) );
return call...

How to convert a std::string to const char* or char*?
...ACK WHERE MAXIMUM SIZE OF x IS KNOWN TO BE COMPILE-TIME CONSTANT "N"

Spring RestTemplate - how to enable full debugging/logging of requests/responses?
..., but conveniently avoids the issue of logging the response, which takes a bit more work. Paul Sabou provides a solution that seems realistic, but doesn't provide enough details to actually implement (and it didn't work at all for me). Sofiene got the logging but with a critical problem: the respons...
