循环语句嵌套判断

  import java.util.*;
  public class Demo10{
  public static void main(String[] args){
  Scanner input = new Scanner(System.in);
  System.out.println("请输入账号");
  int a = input.nextInt();
  System.out.println("请输入密码");
  int b = input.nextInt();
    if(a==1234){
        if(b==12345){
            System.out.println("登录成功");
        }else{
            System.out.println("密码不正确");
          }
        }else{
        System.out.println("账号不正确");
    }
 }
