Android平台对应的高欢堂所编写的书籍的对应源代码 可以不用敲键盘了

class Pair<T1, T2> {
	T1 key;
	T2 val;
	Pair(T1 a, T2 b){
		key = a;
		val = b;
	}
    public T1 get_key()
    {
    	return key;
    }
	public T2 get_val()
	{
		return val;
	}
	
}


public class bbb {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		Pair<String, Object> pair = 
			new Pair<String, Object>("dog", new String("DOG"));
		System.out.println(pair.get_key());
		System.out.println(pair.get_val());
		

	}
