Question

以下是Java程序的预期输出。

Hello. What is your name? 
 Hi John! How old are you? 
 So you're 22 eh? That's not old at all! 
 How much do you make John?


 500.0! I hope that's per hour and not per year! LOL!

预期投入： John 22 500（我需要水平输入，而不是垂直输入。）

那么我需要做出哪些改变？像任何函数scanner.next()而不是nextLine()一样，或者如何使用？

你能说出我的节目中有什么问题吗？

public class Test2 {
   public static void main(String args[]) {

       Scanner scanner = new Scanner(System.in);
       Scanner in = new Scanner(System.in);
       Scanner inc = new Scanner(System.in);

       String xyz = scanner.nextLine();
       int age = in.nextInt();
       double cme = inc.nextInt();
       System.out.println("Hello.What is your name?");
       System.out.println("So you're "+age+"eh?That's not old at all!" );
       System.out.println("hi"+xyz+"!How old are you?");
       System.out.println("How much do you make"+xyz+"?");
       System.out.println(+cme+"!I hope that's per hour and not per year!LOL!");
   }
}

Answer 1

使用分割功能。

 String s = scanner.nextLine();
 String[] inputs = s.split(" ");

如果输入是John 22 500输入将等于[“John”，“22”，“500”]

您可以通过执行

将第1项和第2项转换为整数

int age=Integer.valueOf(inputs[1])

和

int pay = Integer.valueOf(inputs[2])

水平获取键盘输入？
