Hi, Can anyone go through my code to brush it up?I got the correct output,printed below, but i need some polishing of the below loop assignment.
1.Should i be using 2 while loops?
2.Regarding the output-How can i align the verticle columns and the output neatly.

public class MK{
	public static void main(String[] args){
		double ks;
		double ml;
		
		System.out.printf("\n%s%20s%20s%20s\n","Miles(ms)","Kilometers(ks)","Kilometers(km)","Miles(ml)");
		
		double km = 20,ms = 1;
		while( ms <= 10 ) {
		while( km <= 65 ) {
			ks =( 1.609*ms );
			ml =( km/1.609 );
			System.out.printf( "%1.0f%19.3f%15.0f%30.3f\n",ms,ks,km,ml );
			ms +=1;
			km +=5;
		}
		}
			
			
		
	}
}

OUTPUT

Miles(ms) Kilometers(ks) Kilometers(km)      Miles(ml)

1. If there are two loops just because there are two termination conditions then no, one is enough if you AND the two conditions together:
while (condition1 && condition2) { ...
2. printf formats have an optional width spec that sets the column width (by left-adding with blanks). Documentation is in the usual places.

i dont understand ur answer 2.

Check out the format specs for printf. You can format the Miles column so its always the same width, so all the subsequent columns line up properly.
