Hi Crispin, How you doing?
Your original question never did get a satisfactory answer.
However it's definitely not the same as Luigi's.
Perhaps you could try the code below; on Suns Windows JDK1.2
the total
stays constant at 1m, and the free highwater mark hovers
around 820k,
at least for the first 4 million iterations round the inner
loop.
My linux died, so I can't try it here (
Nick
public class SBTest2 {
public static void main( String[] args ) {
int i = 0;
while(true) {
long free = Runtime.getRuntime().freeMemory();
long total = Runtime.getRuntime().totalMemory();
for( int j = 0; j < 1000; j++ ) {
System.out.println(i + ", free = " + free + ",
total = " + total );
i++;
}
}
}
}
