我的代碼有什麼問題？

Question

我似乎不能跳過while循環，因爲我的代碼不明白我輸入了正確的數字。

import java.util.Scanner; 
public class HelloWorld1{ 
    static Scanner userInput = new Scanner(System.in); 
     static int randomNumbe 

public static void main(String[] args){ 
    System.out.println(randomNum()); 
    int randomGuess = -1 ; 
    while(randomGuess != randomNum()){ 
     System.out.println("Guess a number between 0 to 100"); 
     randomGuess = userInput.nextInt(); 
    } 
    System.out.println("Yes the random number is:" + randomGuess); 
} 

public static int randomNum(){ 
    randomNumber = (int) (Math.random()*101); 
    return randomNumber; 
} 

}

Answer 1

當你調用randomNum（），你得到另一個隨機值回。嘗試：

int expected = randomNum(); 
System.out.println(expected); 
int guess = -1; 
while(guess != expected) { 
    ... 
} 

Answer 2

package randomguess; 

import java.util.Scanner; 

public class RandomGuess { 

/** 
* @param args the command line arguments 
*/ 

static int randomNumber = 0; 

public static int getRandomInt() { 
    randomNumber = (int) (Math.random()*101); 
    return randomNumber; 
} 

public static void main(String[] args) { 

    Scanner sc = new Scanner(System.in); 

    int guessInt = sc.nextInt(); 
    int randomInt = getRandomInt(); 

    while(guessInt != randomInt) { 
     System.out.println("Better luck nextTime :D Random number was "+randomInt); 
     guessInt = sc.nextInt(); 
     randomInt = getRandomInt(); 
    } 
    System.out.println("Yeah! You are oracle!"); 
    } 
} 

這可能是你想要的東西。讓我知道如果是。
