猜数小游戏

#include<iostream>
#include<stdlib.h>
using namespace std;
int count = 0;
bool judge (int num,int ynum){
    if(num == ynum){
        cout<<"You got it right in "<<count<<" guesses"<<endl;
        return true;
    }

    else if (num>ynum){
        cout<<"It`s higher."<<endl;
        return false;    
    }
    else{
        cout<<"It`s lower."<<endl;
        return false;    
    }
}
int main(){
    int num = rand()%100+1;
    int ynum;
    cout<<"I`m thinking of a number between 1 and 100..."<<endl;
    bool nether= false; 
    while(!nether){
        count++;
        cout<<"Your guess? ";
        cin>>ynum;
//        cout<<endl;
        nether = judge(num,ynum);
        
    }
}

 上面的是用C++写的简单的一个回合的游戏，现在用Java写一个完整的游戏过程，并在最后有游戏总结。

package LAB1;
import java.util.*;

public class Guess {
	public static final int range=100;
	static int best=100000,total_num=1,guess_times_sum=0;

	public static void main(String[] args){
		Scanner console=new Scanner(System.in);
		Random rand=new Random();	
		System.out.println("Welcome to the Guessing Game program
");
		best=Game(console,rand);
		Again(console,rand);
		System.out.println("  best game   = "+best);
	}
	
	public static int Game(Scanner console,Random rand){
		System.out.println("I'm thinking of a number between 1 and "+range+"...");
		int guesstimes=0;
		int guessnum;
		int randnum=rand.nextInt(range);
		do {
			System.out.print("Your guess? ");
			guessnum=console.nextInt();
			if(guessnum>randnum){
				System.out.println("It's lower.");
			}
			else if(guessnum<randnum){
				System.out.println("It's higher.");
			}
			guesstimes++;
		}while(guessnum!=randnum);
		System.out.println("You got it right in "+guesstimes+" guesses");
		guess_times_sum+=guesstimes;
		if(best>guesstimes){
			best=guesstimes;
		}
		return best;
	}
	

	public static void Again(Scanner console,Random rand){
		System.out.print("Do you want to play again? ");
		String YorN=console.next();
		if(YorN.startsWith("y")||YorN.startsWith("Y")){
			System.out.println();
			Game(console,rand);
			total_num++;
			Again(console,rand);

		}
		else if(YorN.startsWith("n")||YorN.startsWith("N")){
			end(console,rand,total_num,guess_times_sum);
		}
		else{
			Again(console,rand);
		}
	}
	
	public static void end(Scanner console,Random rand,int m,int n){
		System.out.println();
		System.out.println("Overall results:");
		System.out.println("  total games   = "+m);
		System.out.println("  total guesses = "+n);
		System.out.println("  guesses/game  = "+(double)n/m);

	}
