用java编写一个猜字游戏程序，答案不限

import java.util.Scanner

public class Test {

public static void main(String[] args) {

int guessTime = 8

boolean restart = true

while (restart) {

System.out.println("请选择下列选项！")

System.out.println("1 ----开始猜数")

System.out.println("2 ----游戏参数设置")

System.out.println("9 ----退出")

boolean flag = true

String choose = null

Scanner in = null

while (flag) {

in = new Scanner(System.in)

choose = in.next()

if (!choose.matches("[129]")) {

System.out.println("输入错误，请重新输入")

continue

} else {

break

}

}

if ("2".equals(choose)) {

boolean chooseLevel = false

System.out.println("请选择游戏难度！")

System.out.println("1 ----难(4次)")

System.out.println("2 ----一般(6次)")

System.out.println("3 ----容易(8次)")

while (!chooseLevel) {

String s = in.next()

if (s.matches("[123]")) {

switch (Integer.parseInt(s)) {

case 1:

guessTime = 4

chooseLevel = true

break

case 2:

guessTime = 6

chooseLevel = true

break

case 3:

guessTime = 8

chooseLevel = true

break

default:

System.out.println("你输入的选择不存在(请输入1、2、3)")

break

}

} else {

System.out.println("你输入的选择不存在(请输入1、2、3)")

}

}

continue

}

if ("9".equals(choose)) {

System.exit(0)

}

if ("1".equals(choose)) {

String number = String.valueOf(Math.round(Math.random() * 100) + 1)

System.out.println(number)

boolean getIt = false

int count = 0

while (!getIt &&++count <= guessTime) {

System.out.println("请输入你猜的值(1-100)")

String s = in.next()

if (s.matches("\\d+")) {

try {

if (Integer.parseInt(s) == Integer.parseInt(number)) {

getIt = true

break

} else if (Integer.parseInt(s) >Integer.parseInt(number)) {

System.out.println("你输入的数字大了！")

} else {

System.out.println("你输入的数字小了！")

}

} catch (NumberFormatException e) {

System.out.println("你输入的数据超过Integer的最大范围！")

continue

}

} else {

System.out.println("你输入的数据不合法！")

continue

}

}

if (getIt) {

System.out.println("恭喜你猜对了，你的战斗力是" + Math.round((1 - count * 1.0 / guessTime) * 100) + "%")

} else {

System.out.println("超过次数,尚需努力")

}

in.nextLine()

in.nextLine()

}

}

}

}

你好，看你的要求估计你们没有学集合，所以就给你写了个数组的：

public class Words {

static public int mostFrequent(int[] list) {

int max = 0

int index = 0

for(int i=0i<list.lengthi++){

if(max <list[i]){

max = list[i]

index = i

}

}

return index

}

static public int onList(String word, String[] list) {

for(int i=0i<list.lengthi++){

if(word.equals(list[i])){

return i

}

}

return -1

}

public static void main(String[] args) {

String str = "my sister ha ha,She me love to get set Me my girl tree me" //测试的，这个你可以随意

String[] words = str.toLowerCase().replace('.',' ').replace(',',' ').replace(" ", " ").split(" ")

int len = words.length

//考虑到二维数组不方便所以这里使用两个数组，二者之间是一一对应的

int[] count = new int[len]

String[] ss = new String[len]

for (int i=0i<words.lengthi++) {

String word = words[i].trim()

int f = onList(word,words)

if(f == -1){

ss[i] = word

count[i] = 1

}else{

ss[f] = word

count[f] += 1

}

}

int index = mostFrequent(count)

System.out.println("出现次数最多的单词是：" + ss[index] + "出现的次数为：" + count[index])

}

}
