我必須編寫一個代碼，讓用戶猜測計算機選擇的數字。我還需要使用布爾值 true 或 false 來告訴用戶用戶是否正確。我嘗試使用 if else 語句，但我還沒有在 Java 中學習這一點。這是我到目前為止所擁有的：import java.util.*;public class RandomGuessMatch{ public static void main(String[] args) { boolean right = true; int MAX = 5; int MIN = 1; int guess; int random; Scanner ask = new Scanner(System.in); System.out.println("Input your guess between 1 through 5."); guess = ask.nextInt(); random = MIN + (int)(Math.random() * MAX); System.out.println("Your guess was " + guess); System.out.println("The random number was " + random); if (right = }}

你必須閱讀java中的if else。那就是條件語句。就像如果你想在某個條件為真時執行某件事，否則如果條件不滿足，它將執行其他部分。
if(condition) {
//Some task
} else {
// some task
}
就像您可以在代碼中添加 if else 一樣。
import java.util.*;
public class RandomGuessMatch
{
public static void main(String[] args) {
boolean right = true;
int MAX = 5;
int MIN = 1;
int guess;
int random;
Scanner ask = new Scanner(System.in);
System.out.println("Input your guess between 1 through 5.");
guess = ask.nextInt();
random = MIN + (int)(Math.random() * MAX);
System.out.println("Your guess was " + guess);
System.out.println("The random number was " + random);
if (guess == random) {
right = true;
} else {
right = false;
}
System.out.println(right);
}
}

對于這么簡單的問題，你應該多谷歌一下。
反正：
如果變量right是Boolean：
??if?(right)?{
???????//?do?something
??}添加回答
