Question

    for (int i = 1; i <= value; i++) {
        System.out.print("Player " + i + ", Please Enter your name : ");
        String PlayerName = input.nextLine();
        System.out.print("Please enter a number between 0 and 9 : ");
        int PlayerNumber = input.nextInt();
        System.out.println(PlayerName + " : " + PlayerNumber);
    }

输出：Player 1, Please Enter your name : Please enter a number between 0 and 9 :

如果我将input.nextLine更改为input.next，则会等待用户首次输入，但他/她将无法写出其全名。

我的问题：我可以更改什么，以便用户可以先输入他的全名，然后输入他的号码？

Answer 1

在input.nextInt()

之后使用 newLine

for (int i = 1; i <= value; i++) {
    input.nextLine(); //add this to top
    System.out.print("Player " + i + ", Please Enter your name : ");
    String PlayerName = input.nextLine();
    System.out.print("Please enter a number between 0 and 9 : ");
    int PlayerNumber = input.nextInt();

    System.out.println(PlayerName + " : " + PlayerNumber);
}

如何使我的nextLine（）等待用户的输入？
