用java寫猜字母的小游戲；隨機生成幾個字母，玩家輸入幾個數(shù)與隨機生成的數(shù)進行比較。
這個行不 ？？？？

/**
* 1.難度選項選擇；
* 2.隨機生成相應數(shù)量的字符，并裝入數(shù)組；

* 轉(zhuǎn)換為大寫字母 轉(zhuǎn)換為小寫。

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.; 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??{
//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().();?//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.();?//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;i<chs.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;i<chs.length;i++){
for(int?j=0;j<input.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;
}
}
用Java編程實現(xiàn)一個猜數(shù)字的游戲：系統(tǒng)隨機產(chǎn)生一個1~100的數(shù)字，然后讓玩家猜測這個數(shù)字，如果玩家猜錯，
1.int num = (int)(Math.random()*100+1);//隨機得出一個1~100的數(shù)
2.用一個變量去接收玩家輸入的數(shù),例如int i;
3.用if語句,當玩家輸入的數(shù)與隨機數(shù)相等時(i==num),則輸出語句(恭喜你猜對了).
4.用else寫出猜錯是的語句.
大致思路就是這樣.建議你自己去寫,只有自己寫過才會懂.如有不懂的M我,本人也在學習中,大家可以相互討論討論.另外你可以把數(shù)字設置成1~10;這樣的話比較容易出現(xiàn)猜對的情況,方便你驗證程序是否正確,然后再改成1~100;
*在說下Math.random(),這個方法得到是一個0~1之間的隨機小數(shù)(不包括1但包括0),所以(0~1)*100=0~100(但是不包括100),然后+1就得出1~100了;因為Math.random()是個小數(shù)所以用int強轉(zhuǎn).
JAVAWEB猜數(shù)字游戲1到100（這是老師給的思路*按照老師給的思路來）
public class Test {
public static void main(String[] args) {
int b = (int) (Math.random()*100 + 1);
while (true) {
try {
Scanner in=new Scanner(System.in);
int a=in.nextInt();
if(a < 1 || a > 100) {
System.out.println("范圍不合法");
} else if(a > b) {
System.out.println(a + "太大");
} else if (a < b) {
System.out.println(a + "太小");
} else {
System.out.println("你終于猜對了");
break;
}
} catch(Exception e) {
System.out.println("數(shù)字格式不合法");
continue;
}
}
}
