you can use the JVM variable "javaw -ms 64m -mx 512m yourApplicationName"
the "-ms 64m " is the small JVM size,
"-mx 512m "is the large size of JVM size.

you can write a loop, in the loop you can invoke the
for(int i = 0 ; i < 600; i++){
Toolkit.getDefaultToolkit().beep();
try{
Thread.sleep(100);
}catch(Exception e){
}
}
