我自己编写的一个小程序,没有用到什么高深的技术,都是些基础的,希望对你有帮助public class GuessNum {
public static void main(String[] args) {
GuessNum.play()
}
static Scanner sc = new Scanner(System.in)
static int guessCount = 0
// 生成不重复的随机数
public static String[] generationNum(int count){
String [] sNum = new String[count]
int n = 10
Random ran = new Random()
boolean[] bool = new boolean[n]
int num = 0
for(int i=0i<counti++){
do{
num = ran.nextInt(n)
}while(bool[num])
bool[num] = true
sNum[i] = String.valueOf(num)
}
return sNum
}
// 获取猜测结果
public static String getResult(String[] num, String inputNum){
String resultMessage = ""
int rightInAll = 0
int rightInNum = 0
int numLength = inputNum.length()
// 根据输入的数与生成的数作比较(这里判断输入数有生成的数,且位置相同)
for(int i=0i<num.lengthi++){
// 判断输入数与生成数各位数是否相同
if(num[(num.length-1) - i].equals(inputNum.substring(numLength - 1, numLength))){
rightInAll++
}
numLength--
}
// 这里判断输入数有生成的数,但位置不同
for(int j=0j<num.lengthj++){
if(inputNum.indexOf(num[j]) >-1){
rightInNum++
}
}
resultMessage = rightInAll + "A" + (rightInNum - rightInAll) + "B"
return resultMessage
}
public static void startGame(int count){
boolean continueOrNot = false
String resultNum = ""
String [] num = GuessNum.generationNum(count)
for(int i=0i<num.lengthi++){
resultNum += num[i]

do{
System.out.print("input:")

if(inputNum.length() >count){
System.out.println("The max length is " + count)

}
public static void play(){
boolean again = false
int count = 4
do{

按这这个步骤走,里面自动生成的代码我有改过,这样自己比较好去认识.
