java - 我正在尝试给我的扫描仪打电话，但它不起作用。我该怎么办？

import java.util.Scanner;

public class Words
{
    public static void main (String[] args)
{
    Scanner myScan = new Scanner(System.in);
    String s1;
    int myAge;
    int time = 6;

    System.out.print("What is your name? ");
    s1 = myScan.nextLine();

    System.out.print("How old are you? ");
    myAge = myScan.nextInt();

    System.out.println("Really? Cause I am " + (myAge+3) + ". " + "Lets's meet up! ");
    s1 = myScan.nextLine();

    }
}

//在执行完最后一条命令后，它不会让我在终端窗口中键入任何内容。请帮忙。

最佳答案

在之间添加nextLine()

System.out.print("How old are you? ");
myAge = myScan.nextInt();

myScan.nextLine(); // add this

System.out.println("Really? Cause I am " + (myAge+3) + ". " + "Lets's meet up! ");
s1 = myScan.nextLine();

这是必需的，因为nextInt()仅消耗读取的int值，而不消耗其后的任何行尾字符。

nextLine()将使用\r\n（或任何行尾/分隔符），而下一个标记将可供其他nextLine()使用。
