 sciuriware,

from http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21121871.html#12015860

I am also in need of that code. I have tested ur code. But I do not understand how to include with in classes.

1. When I execute this I use Java.exe as Runtime JVM whereas ur application takes javaw as runtime JVM. May I know the reason for this
2. When I tested this I am not getting anythig printed on screen. Is my perception of understanding that code is wrong??
Please clarify me

Thanks
Sudhakar



             public static void main(String[] argv) throws Throwable
          {
             
                new NeedMemory().needMemory(400, argv); // 400Mb limit, 200Mb initial.
                    System.err.println("Hello There");
                    StringBuffer sb=new StringBuffer("Hello World ");
                    try
                 {
                    while(true)
                 {
                         sb.append(sb.toString());
                                          System.err.println(sb.length());
                 }
                 }
                 catch(Throwable e)
                 {
                      System.err.println(sb.length());
                 }
                 System.err.println(sb.length());
            }

I must admit that the javaw thing is a MSWindows java that avoids an MSDOS box.

Do you realise that the above code explodes like a bomb?

Feel free to change the code I posted.
It works for me and for the original questioner.
If you understand it, you can change it to your needs.


I'm going home now. See you.

;JOOP!

That is what I am facing. Some times it  takes entire RAM. Why So??

Because it never stops doubling a String; even some ExaBytes of memory (a lot) are not enough!
