Simply write a method to test the Java garbage collection mechanism

System.GC () can alert the JVM virtual machine to garbage collection, but it is not necessarily successful.

/** * Overwrite the Finalize () method in Object */public class LJ {    @Override    protected void Finalize () throws Throwable {        Syste M.out.println ("Garbage is being recycled .....");}    public class Gcdemo {    /**     * @param garbage collection mechanism test     */public    static void Main (string[] args) {            new LJ (); 
  new LJ ();            New LJ ();            New LJ ();            New LJ ();            System.GC ();}
