JAVA小练习61——接口的练习

interface A{
	
	public static final	int i =10;

	 public abstract void test();

}

//实现了A接口...
class Demo61  implements A{
	
	public static void main(String[] args) 
	{
		
		Demo61 d  = new Demo61();
		d.test();
	}

	public void test(){
		System.out.println("这个接口的test方法...");
	}
}
