Garbage Collection facilitation by assigning variables to null

Question

Hello,
I understand Garbage Collection (GC) can be facilitated by assigning variables to null. Is this true for all variables?
I have a class and there are some member variables which are strings. Also i have some methods with some string variables declared and defined inside the method. I am assigning null to class member variables and also the string variables of the method.
is it correct to assign null and faciliate GC for the string variables declared and defined inside the method?
Class A {
String t1;
public void test() {
String t2 = "test";
// processing
t2 = null; // Will this facilitate GC?
public static void main (String[] args) {
test();
A obj = new A();
A.t1 = "testclass";
A.t1 = null; // Will this faciliate GC?
Thanks, Aravinth

In fact, the java heap is divided into a space for new allocations, and two survivor spaces. The algorithm for when collection occurs in each space is complex, and tuning GC is an interesting topic all its own. Follow the best advice you have been given ... chillax. The JVM has GC under control.
<think/> Of course, having said this, you can have memory leaks if you create references that never go out of scope, even if they are no longer used. Avoid this.
