8.1 Java 泛型实现

pln函数 用 类似C++的 teplate形式 接受任意类型参数

class Euphonium{
	String nameString;
	public Euphonium() {}
	public Euphonium(String nameString) {
		this.nameString = nameString;
	}
	@Override
	public String toString() {
		return "This is Kitauji [Euphonium] ~~~ :"+nameString;
	}
}
class Kumiko extends Euphonium{
	public String nameString; 
	public Kumiko(String nameString) {
		super(nameString);
		this.nameString = "Kousaka Reina";
	}
}
public class Mine{
	static <T> void pln(T nameString) {
		System.out.println(nameString);
	}
	public static void main(String[] args) {
		Kumiko Address = new Kumiko("Oumae");
//		System.out.println(Address);
//		System.out.println(Address.nameString);
		pln(Address);
		pln(Address.nameString);
	}
}
