java如何實現(xiàn)的簡單猜數(shù)字游戲代碼

主要通過隨機數(shù)與邏輯判斷來實現(xiàn)游戲功能

實現(xiàn)代碼如下：

import java.util.InputMismatchException;

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

// 產(chǎn)生一個隨機數(shù)

int number = (int) (Math.random() * 100) + 1;

// 加入count

int count = 0;

// 在這里加入最大值，和最小值

int max = 100;

int min = 1;

while (true) {

// 鍵盤錄入數(shù)據(jù)

Scanner sc = new Scanner(System.in);

System.out.println("請輸入你要猜的數(shù)據(jù)：(" + min + "~" + max + ")");

try {

count++;

int guessNumber = sc.nextInt();

// 判斷

if (guessNumber number) {

max = guessNumber;

System.out.println("你猜大了");

} else if (guessNumber number) {

min = guessNumber;

System.out.println("你猜小了");

} else {

System.out.println("恭喜你,花了" + count + "次就猜中了");

// 問是否繼續(xù)

System.out.println("請問還要繼續(xù)嗎？(yes)");

sc = new Scanner(System.in);

String str = sc.nextLine();

if ("yes".equals(str)) {

// 重寫賦值隨機數(shù)

number = (int) (Math.random() * 100) + 1;

count = 0;

max = 100;

min = 1;

} else {

break;

}

}

} catch (InputMismatchException e) {

System.out.println("你輸入的數(shù)據(jù)有誤");

}

}

}

如何用Java語言實現(xiàn)猜數(shù)字游戲

java實現(xiàn)的簡單猜數(shù)字游戲代碼,通過隨機數(shù)與邏輯判斷來實現(xiàn)游戲功能 代碼如下： import java.util.InputMismatchException; import java.util.Scanner; public class Main { public static void main(String[] args) { // 產(chǎn)生一個隨機數(shù) int n

用java編寫一個猜數(shù)字游戲，

package?day06;

import?java.util.Scanner;

//猜字符游戲

public?class?GuessingGame?{

//主方法

public?static?void?main(String[]?args)?{

Scanner?scan?=?new?Scanner(System.in);

int?count?=?0;?//猜錯的次數(shù)

char[]?chs?=?generate();?//隨機生成的字符數(shù)組

System.out.println(chs);?//作弊

while(true){?//自造死循環(huán)

System.out.println("猜吧!");

String?str?=?scan.next().toUpperCase();?//獲取用戶輸入的字符串

if(str.equals("EXIT")){?//判斷str是否是EXIT

System.out.println("下次再來吧!");

break;

}

char[]?input?=?str.toCharArray();?//將字符串轉(zhuǎn)換為字符數(shù)組

int[]?result?=?check(chs,input);??//對比

if(result[0]==chs.length){?//位置對為5

int?score?=?chs.length*100?-?count*10;?//一個字符100分，錯一次減10分

System.out.println("恭喜你猜對了，得分:"?+?score);

break;?//猜對時跳出循環(huán)

}else{?//沒猜對

count++;?//猜錯次數(shù)增1

System.out.println("字符對:"+result[1]+"個，位置對:"+result[0]+"個");

}

}

}

//隨機生成5個字符數(shù)組

public?static?char[]?generate(){

char[]?chs?=?new?char[5];

char[]?letters?=?{?'A',?'B',?'C',?'D',?'E',?'F',?'G',?'H',?'I',?'J',

'K',?'L',?'M',?'N',?'O',?'P',?'Q',?'R',?'S',?'T',?'U',?'V',

'W',?'X',?'Y',?'Z'};

boolean[]?flags?=?new?boolean[letters.length];?//1.

for(int?i=0;ichs.length;i++){

int?index;

do{

index?=?(int)(Math.random()*letters.length);?//0到25

}while(flags[index]==true);?//2.

chs[i]?=?letters[index];

flags[index]?=?true;?//3.

}

return?chs;

}

//對比隨機數(shù)組與用戶輸入的數(shù)組

public?static?int[]?check(char[]?chs,char[]?input){

int[]?result?=?new?int[2];

for(int?i=0;ichs.length;i++){

for(int?j=0;jinput.length;j++){

if(chs[i]==input[j]){?//字符對

result[1]++;?//字符對個數(shù)增1

if(i==j){?//位置對

result[0]++;?//位置對個數(shù)增1

}

break;

}

}

}

return?result;

}

}

java猜數(shù)字小游戲代碼怎么寫？

import?java.util.Scanner;

public?class?Guess?{

private?static?final?int?F?=?1;

private?static?final?int?T?=?100;

public?static?void?main(String[]?args)?{

int?num?=?(int)(Math.random()?*?T)?+?F;

Scanner?s?=?new?Scanner(System.?in?);

//?初始化

int?guest?=?-1;

while?(true)?{

System.out.print("請輸入你猜測的數(shù)字("?+?F?+?"-"?+?T?+?")：");

//?每次輸入的值，采納即可

guest?=?s.nextInt();

if?(guest??num)?{

System.out.println(F?+?"--"?+?guest);

}?else?if?(guest??num)?{

System.out.println(guest?+?"--"?+?T);

}?else?{

System.out.println("中獎了");

break;

}

}

s.close();

}

}

簡單的java猜數(shù)字代碼

public static void main(String [] args){

int[] num_list={1,3,5,7,9};

java.util.Scanner str=new java.util.Scanner(System.in);

int num = str.nextInt();

for(int i=0;inum_list.length;i++){

if(num!=nullnum.equals("")){

if(num_list[i]==num){

System.out.println("恭喜你，猜對了!");

}else{

System.out.println("抱歉，你猜錯了!");

}

}

}

}
