-----------------------用户登陆原----------------------------

public class Check {

    public static void main(String[] args) {

        //创建一个adm数组
        Admin[] adm = new Admin[3];

        //三个账号
        adm[0] = new Admin("admin", "pastNumber");
        adm[1] = new Admin("admin1", "pastNumber");
        adm[2] = new Admin("admin2", "pastNumber");

        //使用标准输入流函数，从键盘输入一些信息
        Scanner scan = new Scanner(System.in);
        System.out.println("请输入你的账号：");

        //将输入的账号放入putName
        String putName = scan.next();
        System.out.println("请输入你的账号密码：");

        //将输入的密码放入普通putPassNumber中
        String putPassNumber = scan.next();

        //新建一个布尔型和整型数据，布尔值用于判断，整型判断是那个账号登陆
        boolean past = false;
        int pastN = 0;

        //判断账号密码是否正确
        for(int i=0;i<adm.length;i++){
            if(adm[i].getName().equals(putName)&&adm[i].getPastNumber().equals(putPassNumber)){
                past = true;
                pastN = i;
                break;
            }
        }

        //输出账号密码是否正确
        if(past){
                System.out.println("欢迎" + adm[pastN].getName() + "登陆");
            }
        else{
                System.out.println("输入有误，请正确输入你的账号和密码！");
            }
    }

}
class Admin{
    private String name;
    private String pastNumber;

    Admin(String name, String pastNumber){
        this.name = name;
        this.pastNumber = pastNumber;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPastNumber() {
        return pastNumber;
    }

    public void setPastNumber(String pastNumber) {
        this.pastNumber = pastNumber;
    }

}

运行结果为：
