How do I keep track of a number in java?
It is in a loop that multiplies the number by 2. I need to know how to keep track of each result.
For example, if I enter 5, I want it to keep and display the number 10, 20, 40, 80.. etc. All in one line outside the loop.

public class TrackTwos {
public static void main( String[] args ) {
String accumulator = "";
int multiple = 5;
for( int i = 0; i < 40; i++ ) {
multiple *= 2;
accumulator += multiple + ",";
}
System.out.println( multiple );
}
}
