Complete the following program to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported. Hint: The value of factor1 or factor2 should be the conversion factor from the selected unit to cm. Ex: If the selected unit is in, factor1 is 2.54 because 1 in = 2.54 cm. import java.util.Scanner; public class UnitConverter{ public static void main(String[] args) { Scanner in = new Scanner(System.in); boolean done = false; double factor1 = 0; double factor2 = 0; String unit1 = ""; String unit2 = ""; while (!done) { boolean getSecond = true; String command = in.next(); System.out.println("From unit (in, cm, m, again, quit): " + command); if (command.equals("in")) { factor1 = 2.54; // Convert to cm unit1 = command; } else if (command.equals("cm")) { /* Your code goes here */ } else if (command.equals("m")) { /* Your code goes here */ } else if (command.equals("again")) { getSecond = false; } else if (command.equals("quit")) { done = true; getSecond = false; } else { System.out.println("Sorry, unknown unit.\n"); getSecond = false; } if (getSecond) // If 'from' unit is valid, get 'to' unit { unit2 = in.next(); System.out.println("To unit: " + unit2); if (unit2.equals("in")) { factor2 = 2.54; // Convert from cm } else if /* Your code goes here */ else if /* Your code goes here */ else /* Your code goes here */ } if (/* Your code goes here */) { double value = in.nextDouble(); double result = value * factor1 / factor2; System.out.println(value + " " + unit1 + " = " + result + " " + unit2 + "\n"); } } }}
