java定义Student类，让它表示学生类，该类的成员包括

a) 字段成员ID：表示学号；
b) 字段成员Name：表示姓名；
c) 无参构造函数；
d) 带参数的构造函数，其中参数用来初始化类实例中的ID和Name字段成员；
e) 输出自身字段成员信息的方法，方法名为Output；
在main方法中定义Student变量，并它引用该类的实例。通过该变量调用Output方法输出人员信息。

public class Student {
private int ID;
private String Name;


public Student() {
super();
}


public Student(int iD, String name) {
super();
ID = iD;
Name = name;
}


public void Output()
{
System.out.println("人员信息：姓名:"+this.Name+",ID"+this.ID);
}


public static void main(String[] args) {
// TODO Auto-generated method stub
Student stu=new Student(123,"张三");
stu.Output();
}

}
