java输出端口问题

定义交通工具类 Vehicle ，具有重量 weight 、类型 category 属性，具有输出车辆信息 printInfo 方法；定义 Contest 接口，具有参加竞赛 join 方法；
定义汽车类 Car ，维承 Vehicle 类，并增加成员变量 String speed [：存储汽车三次测试的速度值；增加构造方法
Car ( int weight , String category , intLspeed )；重写 printInfo 方法。
实现 Contest 接口，实现其抽象方法 join ，如果最大速度值超过130则输出“可以参加竞赛”，否则输出“功率不够不适合参赛”。然后在 main 方法中测试。
样例 l :
输入：2跑车105150128
们出：
重量：2吨
类型：跑车
速度：105150128可以参加竞赛
样例2:
输入；3 suv 90125110
输出：
重量：3吨
类型： sUV
速度：90125110
功率不够不适合参赛

速度之间没空格的？构造方法的速度类型也不对啊。题目截图看下。

import java.util.Scanner;
public class Car extends Vehicle implements Contest{
    String speed;
    Car ( int weight , String category , String speed){
        this.weight=weight;
        this.category=category;
        this.speed=speed;
    }

    @Override
    public void printInfo() {
        System.out.println("重量："+weight+"吨");
        System.out.println("类型："+category);
        System.out.println("速度："+speed);
    }

    @Override
    public void join() {
        boolean flag=false;
        String[] s = speed.split(" ");
        for(int i=0;i<s.length;i++){
            if (Integer.valueOf(s[i])>130){
                flag=true;
                break;
            }
        }
        if (flag){
            System.out.println("可以参加竞赛");
        }else{
            System.out.println("功率不够不适合参赛");
        }
    }

    public static void main(String[] args) {
        Scanner in=new Scanner(System.in);
        Car car=new Car(in.nextInt(),in.next(),in.nextInt()+" "+in.nextInt()+" "+in.nextInt());
        car.printInfo();
        car.join();
    }
}


class Vehicle {
     int weight;
     String category ;
    public void printInfo(){
    }
}

public interface Contest {
    public void join();
}

成员变量 String speed根据输入的int来生成，join函数中分解出最低速度、最高速度和一般速度，并根据最高速度输出结果。
运行结果：

Vehicle 类：


public class Vehicle {
    protected int weight;
    protected String category;
    public int getWeight() {
        return weight;
    }
    public void setWeight(int weight) {
        this.weight = weight;
    }
    public String getCategory() {
        return category;
    }
    public void setCategory(String category) {
        this.category = category;
    }
    public void printInfo(){
        System.out.println("重量："+weight+"吨");
        System.out.println("类型："+category);
    }

}

Contest接口：

public interface Contest {
    public abstract void join();

}

Car类：


public class Car extends Vehicle implements Contest{
    private String speed;
    public Car(int weight , String category , int speed){
        setWeight(weight);
        setCategory(category);
        this.speed = Integer.toString(speed);
    }

    public String getSpeed() {
        return speed;
    }

    public void setSpeed(String speed) {
        this.speed = speed;
    }

    @Override
    public void join() {
        // TODO Auto-generated method stub
        /*
        最大速度值超过130则输出“可以参加竞赛”，
        否则输出“功率不够不适合参赛”*/
        int maxspeed;
        if(speed.length() == 9){
            maxspeed = Integer.parseInt(speed.substring(3,6));
        }else if(speed.length() == 8 || speed.length() == 7)
            maxspeed = Integer.parseInt(speed.substring(2,5));
        else
            maxspeed = Integer.parseInt(speed.substring(2,4));
        //System.out.println("maxspeed="+maxspeed);
        
        if(maxspeed > 130)
            System.out.println("可以参加竞赛");
        else
            System.out.println("功率不够不适合参赛");
    }
    @Override
    public void printInfo(){
        System.out.println("重量："+weight+"吨");
        System.out.println("类型："+category);
        System.out.print("速度："+speed+" ");
        join();
    }

}

测试类：


import java.util.Scanner;

public class Test {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sc = new Scanner(System.in);
        
        int w = sc.nextInt();
        String cat = sc.next();
        int sp = sc.nextInt();
        Car c = new Car(w,cat,sp);
        c.printInfo();

    }

}

翻译题
把汉语描述翻译成java即可
答题不易 有用请采纳

    public String printInfo() {

        return "重量：" + weight + "吨\n类型：" + category;
