I would like help making UML diagrams for the following code :

import java.util.*;

abstract class SpaceShip{

int numEngines; String name; abstract void ShowSpeed(); }

class ScoutShip extends SpaceShip{ ScoutShip(){

this.numEngines = 1; this.name = "Scout"; } ScoutShip(int numEngines){ this.numEngines = numEngines; this.name = "Scout"; } public void ShowSpeed(){ int speed = numEngines*2; System.out.printf("%s ship can fly at speed %d warp factor ",this.name,speed); } } class ExplorerShip extends SpaceShip{

ExplorerShip(){ this.numEngines = 2; this.name = "Explorer"; } ExplorerShip(int numEngines){ this.numEngines = numEngines; this.name = "Explorer"; } public void ShowSpeed(){ int speed = numEngines*2; System.out.printf("%s ship can fly at speed %d warp factor ",this.name,speed); } } class TestShip { public static void main(String[] args) {

ScoutShip scoutship = new ScoutShip(); ExplorerShip explorership = new ExplorerShip(3); scoutship.ShowSpeed(); explorership.ShowSpeed(); } }
