import java.util.Scanner;

public class Teste2 {
	public static void main(String[] args) {
		Scanner sc =new Scanner(System.in);
		System.out.println("请输入用户名");
		String user,psw;
		user = sc.next();
		System.out.println("请输入密码");
		psw = sc.next();
		if(user.toLowerCase().equals("tom")&& psw.contentEquals("123456")){
			System.out.println("登陆成功");
		}else {
			System.out.println("用户名密码不符合，登陆失败，请重试！");
		}
		
		
	}

}
