I have seen this list several times. Who has written it orginally, and more important, when? Some of the tips are be useful only for old phones.

At least one tip is technically wrong:

In java, you can not set an object to null.

You can only set a variable to null. But this does not affect the object that assigned to the variable. Setting a variable to null creates an extra instruction. So only do it when you know it helps. It can be helpful when

1) the variable does not go out of scope anyway, (e.g. at end of function)

2) the object is bigger, e.g. an image. Then it might help, that the garbage collector gets it.

3) you will not need this image again soon.

otherwise, setting a variable to null is wasting time and space.
