package com.reflect;

public class TestClass
{
	public static void main(String[] args)
	{
		try
		{
			Class c=Class.forName("com.entity.Student");
			Object obj=c.newInstance();
		} catch (ClassNotFoundException e)
		{
			e.printStackTrace();
		} catch (InstantiationException e)
		{
			e.printStackTrace();
		} catch (IllegalAccessException e)
		{
			e.printStackTrace();
		}
	}
}





package com.entity;

public class Student
{
	private String name;
	private int age;
	private int money;
	private String address;
	private Course course;
	
	public Student()
	{
		super();
		System.out.println("student");
	}
	public Student(String name, int age)
	{
		super();
		this.name = name;
		this.age = age;
		System.out.println(this.name+","+this.age);
	}
	public String getName()
	{
		return name;
	}
	public void setName(String name)
	{
		this.name = name;
	}
	public int getAge()
	{
		return age;
	}
	public void setAge(int age)
	{
		this.age = age;
	}
	
	private String getHello()
	{
		return "hello";
	}
