使用Scanner获取键盘输入

import java.util.Scanner;
public class TestScanner {
  public static void main (String[] args) {
    Scanner s = new Scanner(System.in);
    System.out.println("请输入用户名：");
    String uname = s.nextLine();
    System.out.println("请输入你的月薪");
    double monthSalary = s.nextDouble();

    System.out.println("用户名" + uname);
    System.out.println("月薪" + monthSalary);
  }
}
