Assignment GPS including jUnit Tests CSIS-1410 Learning Objectives: . Practice Composition Review declaring classes based on UML class diagrams Use jUnit tests to test and troubleshoot your code Description: Create a new Java project called "1410 Gps". It includes a package named gps Inside the package gps implement the classes Gps and GpsPosition as described below Include doc comments for each of the public methods, for the constructors, and for the classes themselves Use the provided jUnit tests to test and troubleshoot both classes Feel free to add a main method at the end of the classes Gps and GpsPosition to demonstrate the use of the class members. For grading purposes the main methods will be ignored Class GpsPosition: Class GpsPosition represents a position based on a given longitude, latitude, and elevation in meters) Declare class GpsPosition based on the UML class diagram below. Notice that there are no setters. The class is immutable. This means the state of a GpsPosition object can no longer be changed once it has been created Do not add or remove any public methods or constructors (except for main) There should also be NO print statements in class GpsPosition GpsPosition - latitude double longitude: double uble eva + GpsPosition ( latitude: double, longitude: double, elevation double) +getLatitudedouble +getLongitude : doubie + geevaton () : double +toString ): String The getters expose the field values as usual. Constructor: The constructor should implement input validation for If the constructor receives an invalid argument, an IllegalArgumentException should be thrown. Like this: throw new TllegalArgumentException("Invalid latitude and/or longitude" Method toString The method toString should return a String that includes the latitude followed by a comma, a space, the longitude, a space, and then the elevation in parenthesis-like this except with the numeric values Lotitude, Longitude (elevation) Both latitude and longitude should display 6 digits after the decimal point while the elevation should display only one digit after the decimal point. Example: 39.573645, -109.546389 1227.1) Use the jUnit tests to test and troubleshoot Gps Position before moving on to the next class
