类与对象实例，用户登录与注册java_用类和对象编写登录系统

用户信息（用户名，密码，手机号，地址）

   package work;
    
    import java.security.PublicKey;
    import java.util.Scanner;
    
    public class DengLu {//用户类 我这里名字本来应该是User，我这个是个错误；
    
    	private String name;
    	private String mima;
    	private String phone;
    	private String adress;
    	
    	public String getName() {
    		return name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getMima() {
    		return mima;
    	}
    
    	public void setMima(String mima) {
    		this.mima = mima;
    	}
    
    	public String getPhone() {
    		return phone;
    	}
    
    	public void setPhone(String phone) {
    		this.phone = phone;
    	}
    
    	public String getAdress() {
    		return adress;
    	}
    
    	public void setAdress(String adress) {
    		this.adress = adress;
    	}
    	public void register() {
    		System.out.println("输入用户名");
    		Scanner scanner=new Scanner(System.in);
    		String na=scanner.next();
    		System.out.println("输入密码");
    		String mi=scanner.next();	
    		if(this.name.equals(na)&&this.mima.equals(mi))
    		{
    			System.out.println("登录成功");
    		}
    		else {
    			System.out.println("登录失败");
    		}
    	}
    	public void login() {
    		System.out.println("输入用户名");
    		Scanner scanner=new Scanner(System.in);
    		String na=scanner.next();
    		this.name=na;
    		System.out.println("输入密码");
    		String mi=scanner.next();
    		this.mima=mi;
    		System.out.println("输入手机号");
    		String ph=scanner.next();
    		this.phone=ph;
    		System.out.println("输入地址");
    		String addr=scanner.next();
    		this.adress=addr;
    		System.out.println("注册成功");
    		
    	}
    }
	
	测试类：
    package work;
    
    public class Test {
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		DengLu userDengLu=new DengLu();
    		userDengLu.login();
    		System.out.println(userDengLu.getAdress());
    		userDengLu.register();
    	}
    
    }
