POWhat's happening with the Java GC when I move out of scope but still hold a reference?

copied!<p>Basically i'm fairly new to Java and i'm trying to get my head round the following.</p> <pre><code>public class Test { TestObject objectA; public static void main(String args[]) { Test t = new Test(); t.test(); while (true){ try { Thread.sleep(1000); } catch (InterruptedException e) {} System.out.println("Obj A: " + t.objectA.toString()); } } void test(){ Object objectB = new TestObject(1, 1); objectA = (TestObject)objectB; System.out.println("Obj B: " + objectB); objectB = null; System.out.println("Obj B: " + objectB); } </code></pre> <p>}</p> <p>Output: </p> <pre><code>Obj B: TestObject@525483cd Obj B: null Obj A: TestObject@525483cd Obj A: TestObject@525483cd </code></pre> <p>Basically, i'm creating a local object objectB in the Method test() and assigning it's reference to the variable objectA inside the Test object.</p> <p>I then set the local variable to null and verify the reference has been nulled.</p> <p>Now from my understanding here i've just effectively nulled a pointer to the object. The object still exists with objectA holding the only reference. Does this mean that the garbage Collector will not collect the object that was created in a method with narrow scope?</p> <p>If i nulled the pointer to objectA will my object be collected?</p> <p>Sorry if this seems like an obvious question with an answer I just need to be sure I'm understanding what i've already read.</p>
