Ch3 – Putting It All Together

  1. Create a new class named Convert and save it as Convert.java.
  2. Enter the following code and compile.
import java.util.Scanner;

public class Convert {
  public static void main(String[] args){
    double cm;
    int feet, inches, remainder;
    final double CM_PER_INCH = 2.54;
    final int IN_PER_FOOT = 12;
    Scanner in = new Scanner(System.in);
    System.out.println("Exactly how many cm? ");
    cm = in.nextDouble();
    inches = (int)(cm/CM_PER_INCH);
    feet = inches/IN_PER_FOOT;
    remainder = inches % IN_PER_FOOT;
    System.out.printf("%.2f cm = %d ft, %d in\n", cm, feet, remainder);
  }
}
  1. Run the program an enter a number to convert.
