Good day,

Is it a good practice to reinitialize an object with null if it is no longer be used or an expected new initialization comes in?

for example

Objective obj = new Objective();
while( something_will_false_later ){
       //operations that uses Objectives
}
obj=null;

Later, that snippet will be utilized again...

Any advise?

If obj is inside a method, won't it be set to null at the method's conclusion anyways? Then the garbage collector will get it.
