Question

在我的下面一段代码中，我希望比较一段文本文件。但是，出于某种原因，无论用户输入的值是什么类型正确的。

我试图比较价值而不用担心它的情况或任何问题领先或尾随的白色空间。

// Display the question to the user
System.out.println("Question: " + myList.get(random1));

// Accept user input
System.out.print("Please type your answer: ");

// Store the user answer in a variable but lowercase
answer = scanner.nextLine().toLowerCase();
System.out.println();

// Display the officially correct answer from the arraylist
System.out.println("Answer: " + myList.get(random1 +1));

// if the user answer matches the official answer, tell them they're
// correct and award points
// else tell them they suck LOL
if(myList.get(random1 + 1).contains(answer) == false) {
    System.out.println("Correct!");
    totalScore = totalScore + awardedPoints;
    System.out.println("You won " + awardedPoints);
}
else {
    System.out.println("You suckkkkkkk");
}

// Display total accumulated points
System.out.println("Your total points are: " + totalScore);

// Wait for user to hit any key before displaying the next question
System.out.print("Hit Enter");
scanner.nextLine();

Answer 1

试试这个。

// Display the officially correct answer from the arraylist
String correctAnswer =  myList.get(random1 +1); 
System.out.println("Answer: " + correctAnswer); // Instead use a variable

// if the user answer matches the official answer, tell them they're
// correct and award points
// else tell them they suck LOL
if(correctAnswer.equalIgnoreCase(answer)) { // efficient than contains() method
    System.out.println("Correct!");
    totalScore = totalScore + awardedPoints;
    System.out.println("You won " + awardedPoints);
}
else {
    System.out.println("You suckkkkkkk");
}

我的布尔总是正确的
