晚上改了一个实例但觉得还是觉得代码偏多了，希望各位高手改进一下，我是个初学者！
代码如下：
import java.util.Scanner;
class MyPetl {public static void speak(String name) {System.out.println(name + "其实我是猪~o~");}
public static void show(String name, int age, String color, double weight) {System.out.println(name + ",今年" + age + "岁，是" + color + "颜色的，体重是："+ weight + "公斤。");}
public static void eat(String name, String food) {System.out.println(name + "喜欢吃" + food + "哈哈！");}
public static void play(String playname, String name) {System.out.println(playname + "和他的宠物" + name + "玩得好开心啊！");}
public static void jump(double height, String name, double weight) {if (height > 10.0) {System.out.println(name + "真厉害，跳得好高啊！它的体重只有" + weight + "公斤。");} elseSystem.out.println(name + "太胖了，跳不动哟！它的体重竟然有" + weight + "公斤！");}}
public class Cong {public static void main(String[] args) {
Scanner in = new Scanner(System.in);System.out.println("请输入你的名字：");String playname = in.next();System.out.println("请输入宠物的名字：");String name = in.next();System.out.println("请输入宠物的年龄：");int age = in.nextInt();System.out.println("请输入宠物的颜色：");String color = in.next();System.out.println("请输入宠物的体重（公斤）：");double weight = in.nextDouble();System.out.println("请输入宠物最喜欢的食物：");String food = in.next();System.out.println("宠物能跳多远（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);}}
