晚上改了一個實例但覺得還是覺得代碼偏多了，希望各位高手改進一下，我是個初學者！ 代碼如下： import java.util.Scanner; class MyPetl {public static void speak(String name) {System.out.println(name + "其實我是豬~o~");} public static void show(String name, int age, String color, double weight) {System.out.println(name + ",今年" + age + "歲，是" + color + "顏色的，體重是："+ weight + "公斤。");} public static void eat(String name, String food) {System.out.println(name + "喜歡吃" + food + "哈哈！");} public static void play(String playname, String name) {System.out.println(playname + "和他的寵物" + name + "玩得好開心??！");} public static void jump(double height, String name, double weight) {if (height > 10.0) {System.out.println(name + "真厲害，跳得好高??！它的體重只有" + weight + "公斤。");} elseSystem.out.println(name + "太胖了，跳不動喲！它的體重竟然有" + weight + "公斤！");}} public class Cong {public static void main(String[] args) { Scanner in = new Scanner(System.in);System.out.println("請輸入你的名字：");String playname = in.next();System.out.println("請輸入寵物的名字：");String name = in.next();System.out.println("請輸入寵物的年齡：");int age = in.nextInt();System.out.println("請輸入寵物的顏色：");String color = in.next();System.out.println("請輸入寵物的體重（公斤）：");double weight = in.nextDouble();System.out.println("請輸入寵物最喜歡的食物：");String food = in.next();System.out.println("寵物能跳多遠（米）：");double height = in.nextDouble();MyPetl mypetl = new MyPetl();MyPetl.show(name, age, color, weight);MyPetl.speak(name);MyPetl.eat(name, food);MyPetl.jump(height, name, weight);MyPetl.play(playname, name);}}
