我最近开始使用 java 编程并需要帮助。
使用 Programming Java for Dummies，我正在尝试制作一个用户必须猜数字的游戏。一旦用户最终得到正确答案，就会记录并显示尝试次数。
星号线给我带来了麻烦，有什么帮助吗？
import static java.lang.System.out;
import java.util.Scanner;
import java.util.Random;
import javax.swing.JOptionPane;
public class HelloWorld
{
public static void main(String args[])
{
Scanner keyboard = new Scanner (System.in);
out.println("Hello, welcome to the Guessing Game.");
out.println("To begin, pick a random number from 1 - 10: ");
int inputNumber = keyboard.nextInt();
int randomNumber = new Random(1).nextInt(10);
int numGuesses = 0;
while (inputNumber != randomNumber){
out.println();
out.println("You're guess was wrong, try again.");
out.println("Pick an integer from 1-10.");
**int inputNumber = keyboard.nextInt();**
numGuesses++;
}
{
out.println("You won in " + numGuesses + " guesses.");
out.println("Thanks for playing!");
}
}
}
