Question

Complete the following program in java to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported.

[画像:This is a Java program designed to convert units of measurement. Below is the detailed transcription of the code and an explanation of its functionality. ### UnitConverter.java ```java import java.util.Scanner; public class UnitConverter { public static void main(String[] args) { Scanner in = new Scanner(System.in); boolean done = false; double factor1 = 1; double factor2 = 1; String unit1 = ""; String unit2 = ""; while (!done) { boolean getSecond = true; System.out.print("From unit (in, cm, m, again, quit): "); String command = in.next(); if (command.equals("in")) { factor1 = 2.54; // Convert to cm unit1 = command; } else if (command.equals("cm")) { // Add conversion logic here for cm } else if (command.equals("m")) { // Add conversion logic here for m } else if (command.equals("again")) { getSecond = false; } else if (command.equals("quit")) { done = true; getSecond = false; } else { System.out.println("Sorry, unknown unit."); getSecond = false; } if (getSecond) { System.out.print("To unit: "); unit2 = in.next(); if (unit2.equals("in")) { factor2 = 2.54; // Convert from cm } else { // Add conversion logic here for other units } if (/* condition to check valid conversion */) { // Replace with actual condition double value = in.nextDouble(); double result = value * factor1 / factor2; System.out.println(value + " " + unit1 + " = " + result + " " + unit2); } } } } } ``` ### Explanation: 1. **Imports and Class Declaration** ```java import java.util.Scanner; public class UnitConverter { ``` - The program begins by importing the `Scanner` class for reading user inputs. - The `UnitConverter` class is declared as public. 2. **Main Method** ```java public static void main(String[] args) { ``` - The `main` method is the entry point of the program. 3]
