一段关于gc(), runFinalization(), finalize()的代码

暂时没有弄得这段代码，mark一下。

class Chair{
    static boolean gcrun = false;
    static boolean f = false;
    static int created = 0;
    static int finalized = 0;
    int i;
    Chair(){
        i = ++created;
        if(created == 47){
            System.out.println("Created 47");
        }
    }
    public void finalize(){
        if(!gcrun){
            gcrun = true;
            System.out.println("Beginning to finalize after" +
                created + "Chairs have been created");
        }
        if(i == 47){
            System.out.println("Finalizing Chair #47, " +
                "Setting flag to stop Chair creation");
            f = true;
        }
        finalized++;
        if( finalized > created){
            System.out.println("All " + finalized + "finalized");
        }
    }
}
public class Garbage{
    public static void main(String[] args){
        while(!Chair.f) {
            new Chair();
            new String("To take up space");
        }
        System.out.println(
            "After all Chairs have been created:\n" +
            "total created = " + Chair.created +
            ", total finalized = " + Chair.finalized);
        if(args.length > 0){
            if(args[0].equals("gc") || args[0].equals("all")){
                System.out.println("gc():");
                System.gc();
            }
            if(args[0].equals("finalize") || args[0].equals("all")){
                System.out.println("runFinalization():");
                System.runFinalization();
            }
        }    
        System.out.println("bye!");  
    }
}
