基本上，我试图让它让你选择输入石头、布或剪刀，但为了得到纸，例如，我需要先输入石头，然后它会读取代码行让我得到纸如果这是有道理的，

    public static String decideString() {
    Scanner userInput = new Scanner(System.in);
    if (userInput.nextLine().contentEquals("Rock")) {
        System.out.println("You have chosen rock");
    } else if (userInput.nextLine().contentEquals("Paper")) {
        System.out.println("You have chosen paper");
    } else if (userInput.nextLine().contentEquals("Scissors")) {
        System.out.println("You have chosen scissors");
    }

Answer 1

尝试下面的代码。

public static String decideString() {
    Scanner userInput = new Scanner(System.in);
    String in = userInput.nextLine();
    if (in.contentEquals("Rock")) {
        System.out.println("You have chosen rock");
    } else if (in.contentEquals("Paper")) {
        System.out.println("You have chosen paper");
    } else if (in.contentEquals("Scissors")) {
        System.out.println("You have chosen scissors");
    }
