Scanner scn = new Scanner(System.in);
double time = scn.nextDouble();

if(time < 12.00 && time > -1 ){System.out.println(time + " A.M");}

else if(time < 24.00 && time > 11.59){System.out.println(time + " PM");}

else{System.out.println("Time Unknown");}

Answer 1

use decimal formatter.

Answer 2

Yes you can. Instead of using println, you have to use printf, where the f means format. For 2 decimal places, printf("%f.2",time). So if you want three decimal places, make it .3,etc.
