如何用Java语言实现猜数字游戏

java实现的简单猜数字游戏代码,通过随机数与逻辑判断来实现游戏功能 代码如下： import java.util.InputMismatchException; import java.util.Scanner; public class Main { public static void main(String[] args) { // 产生一个随机数 int n

用JAVA编猜数字游戏

1)

程序随机分配给客户一个1—100之间的整数

Random

gen

=

new

Random();

int

a

=

gen.nextInt(100)+1;

//不加1是0到99

2)

用户在输入对话框中输入自己的猜测

Scanner

in

=

new

Scanner(System.in);

System.out.println("give

me

a

number")

int

b

=

in.nextInt();

3)

程序返回提示信息，提示信息分别是：“猜大了”、“猜小了”和“猜对了”。

if(ba)

System.out.println("big");

else

if(ba)

System.out.println("small");

else

System.out.println("right");

4)

用户可根据提示信息再次输入猜测，直到提示信息是“猜对了”。

while(b!=a){

if(ba)

System.out.println("big");

else

if(ba)

System.out.println("small");

System.out.println("give

me

a

new

number")

int

b

=

in.nextInt();

}

System.out.println("right");

3看懂以后,3,4可以合在一起,用4的回答.
