Java：僅輸出字符串的第一個單詞？

Question

我用過Scanner var = input.nextLine（）; 它適用於我的名稱變量，但不適用於地址嗎？ 這是我的代碼：

Scanner input = new Scanner(System.in);

System.out.println("What is your name?");
String name = input.nextLine();

System.out.println("How old are you?");
int age = input.nextInt();

System.out.println("Where do you live?");
String address = input.nextLine();

System.out.println("Your name is " + name + ".\n You are " + age + " years old." + "\n You live at " + address + ".");

這是它的顯示內容：

What is your name?
Yassine assim
How old are you?
17
Where do you live?
Your name is Yassine assim.
 You are 17 years old.
 You live at .

Answer 1

int age = input.nextInt(); 消耗您鍵入的int ，僅此而已，如果沒有使用此char（返回行），則一定要返回行

所以input.nextLine(); 地址將直接執行

2種選擇：

1. int age = Integer.parseInt(input.nextLine()); 取所有行並轉換為int
2. int age = input.nextInt(); input.nextLine(); 接受int並使用，然后消耗諸如
