java学习

刚入门的话就先熟悉 一下代码哦 比如说下面的例子：从网上copy过来就要注意一些细节啦
import java.util.Scanner;
public class lx001 {
  public static void main(String[] args){
      Scanner in=new Scanner(System.in);
      System.out.println("请输入帐号：");
      String a=in.next();
      System.out.println("请输入密码：");
      int password=in.nextInt();
      if(a.equals("yutao")&&password==123456){
          System.out.println("恭喜你，登录成功！");
      }else{
          System.out.println("Sorry.帐号和密码错误");
      }
  }
}
