Comment on Tutorial : Garbage collection and Finalize() method By aathishankaran
/** Example shows garbage collector in action
Note that the finalize() method of object GC1
runs without being specifically called and that
the id's of garbage collected objects are not
always sequential.
*/

class TestGC {

public static void main(String[] args) {

Runtime rt = Runtime.getRuntime();

System.out.println("Available Free Memory: " + rt.freeMemory());

for(int i=0; i<10000; i++ ) {
GC1 x = new GC1(i);
}

System.out.println("Free Memory before call to gc(): " +
rt.freeMemory());
System.runFinalization();
System.gc();
System.out.println(" Free Memory after call to gc(): " +
rt.freeMemory());

}
}

class GC1 {

String str;
int id;

GC1(int i) {
this.str = new String("abcdefghijklmnopqrstuvwxyz");
this.id = i;
}

protected void finalize() {
System.out.println("GC1 object " + id + " has been finalized.");
}

}
