求一個(gè)JAVA猜單詞游戲的代碼，要求如下

import?java.util.Random;

import?java.util.Scanner;

public?class?GuessString?{

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

String[]?strings={"apple","orange","tom","kitty","hello","world","have","fun","hehe","ok"};

String?choosed=strings[rand.nextInt()%10];

StringBuilder?guessString=new?StringBuilder(choosed);

StringBuilder?sb=new?StringBuilder();

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

sb.append("_?");

System.out.println(sb);

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

int?numberGuessed=0;

while(numberGuessedguessString.length()){

char?c=scanner.next().charAt(0);

int?index=guessString.indexOf(c+"");

簡(jiǎn)易電子詞典 無(wú)需數(shù)據(jù)庫(kù) 用map添加單詞及含義的 java源代碼

public class Test4 {

static MapString, String map = new TreeMapString, String();

static {

map.put("watermelon", "西瓜");

map.put("banana", "香蕉");

map.put("strawberry", "草莓");

map.put("apple", "蘋果");

}

public static void main(String[] args) {

System.out.println("請(qǐng)輸入單詞");

Scanner sc = new Scanner(System.in);

while (sc.hasNext()) {

String str1 = sc.nextLine();

if(str1.equals("退出")){

return;

}

else if (map.containsKey(str1)) {

System.out.println(map.get(str1));

} else{

System.out.println("次單詞為新詞,添加意思");

Scanner sc1 = new Scanner(System.in);

String str2=sc1.nextLine();

map.put(str1, str2);

System.out.println("添加成功。");

}

}
