teststudentclass.java

一个很简单的student类

class Student
{
	private long studentId;
	private int classId;
	private String studentName;
	private String studentSex;
	private int studentAge;
	private long BankNum;
	private int Money;
	public Student(String s,String sex,int age,long studentid,int classid,long banknum,int money)
	{	
		studentName = s;
		studentSex = sex;
		studentAge = age;
		studentId = studentid;
		classId = classid;
		BankNum = banknum;
		Money = money;
	}
	public void Deposit(int num){System.out.println("你存了" + num + "元钱");Money += num;}//鉴于存款比较敏感，用private合适
	public void Withdrawl(int num) { System.out.println("你取了" + num + "元钱"); Money -= num; }
	public void OutputMoney() { System.out.println("你现在有" + Money + "元钱"); }
	public long getStudentId()
	{
		return studentId;
	}
	public int getClassId()
	{
		return classId;
	}
	public String getStudentName()
	{
		return studentName;
	}
	public String getStudentSex()
	{
		return studentSex;
	}
	public int getStudentAge()
	{
		return studentAge;
	}
	public void setStudentAge(int age)
	{
		studentAge = age;
	}
	void OutputStudentInfo()//设置输出函数，输出所有信息
	{
		System.out.println("--------------------------------------");
		System.out.println("姓名："+ getStudentName());
		System.out.println("性别:" + getStudentSex());	
		System.out.println("年龄为:"+ getStudentAge());
		System.out.println("Id为:"+ getStudentId());

		System.out.println("---------------------------------------");
	}
}
