Question

In the below example program how many object will be garbage collected before executing line Thread.sleep(1000)?

public class GCExample {

public static void main(String[] args) throws InterruptedException {
    GCExample gc = new GCExample();
    gc.doSomeThing();
    Thread.sleep(1000);
}
public void doSomeThing(){
    Object[] obj = new Object[2];
    for(int i=0;i<obj.length;i++){
        obj[i] = new Object();
    }
}

}

Answer 1

Given the non-deterministic nature of GC, I’d say about the same number as fit the length of a piece of string.
