🌟代码演示

import java.util.*;

public class Main{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        int x=sc.nextInt();
        String[] arr={"Mon","Tues","Wednes","Thurs","Fri","Satur","Sun"};
        System.out.printf("%sday",arr[x-1]);
    }
}

🌟代码演示

import java.util.*;

public class Main{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        Map<Integer,String> type=new HashMap<>();
        type.put(200,"OK");
        type.put(202,"Accepted");
        type.put(400,"Bad Request");
        type.put(403,"Forbidden");
        type.put(404,"Not Found");
        type.put(500,"Internal Server Error");
        type.put(502,"Bad Gateway");
        while(sc.hasNextInt())
            System.out.println(type.get(sc.nextInt()));
    }
}

                if (a == b && b == c) {
                    System.out.println("Equilateral triangle!");
                } else if (a == b || a == c || b == c) {
                    System.out.println("Isosceles triangle!");
                } else {
                    System.out.println("Ordinary triangle!");
                }
            } else {

🌟代码演示

import java.util.*;
public class Main {
    public static void main(String[] args)
    {
        int y=0,m=0,d=0;
        int y1=0,m1=0,d1=0;
        Scanner in=new Scanner(System.in);

        y=in.nextInt();m=in.nextInt();d=in.nextInt();
        y1=in.nextInt();m1=in.nextInt();d1=in.nextInt();
        String result;
        //一共3种情况：年月相同时比较天，年相同时比较月，或者直接比较年
        if((y1==y&&m==m1&&d1>=d)||(y1==y&&m1>=m)||(y1>=y))
        {
            result="yes";
        }
        else{
            result="no";
