内部类如何实例化

内部类不能通过直接new的方式生成实例，而是要通过其外部类的实例来生成实例

public class Student {
	private String name;

	public Student(){}
	
	public Student(String name){
		this.name = name;
	}

	public class Home {
		private String address;
		
		public Home(){}

		public Home(String address){
			this.address = address;
		}
	}

	public static void main(String[] args) throws IOException {
		Student student = new Student("张三");
		Home home = student.new Home("南京路100号");
	}
}

关键点：Home home = student.new Home("南京路100号");
