java - 如何在收到用户输入后执行打印语句

Question

我的代码是:

import java.util.Scanner;
class shoham
{
    public static void main (String args[])
    {
        System.out.println("Enter your name: ");
        Scanner name = new Scanner(System.in);
        System.out.println("Your name is: ");
        System.out.print(name.nextLine());
    }
}

当我执行此命令时，我得到如下输出:

Enter your name:
Your name is: 
*****                               (user input)
*****                                (output)

任何人都可以提供一个可以提供如下输出的代码:

Enter your name: **** - (user input)
Your name is: **** - (output from user input)`

好吧，您正在打印语句之后读取输入。您可能想要:

Scanner in = new Scanner(System.in);  // do this first, and give it a 
                                      // better name

System.out.print("Enter your name: ");  // use print to keep it on one line
String name = in.nextLine();  // read input, store it
System.out.print("Your name is: ");
System.out.println(name);  // print name

Enter your name: JoeYour name is: Joe
