Posted by: ginger547 Posted on: 2005-04-08 15:06 这东西说起来可就难了 建议你去查一下资料 简单一句话 interface是建立东西不实现 等你用的时候 具体实现它 明白了吗 就是放个空架子在那 等你往里塞东西 不知道这样说明白不明白 //MyInterface.java interface MyInterface{ int add(int i); int sub(int j); } //TestInterface.java public TestInterface{ int k=0; int add(int i){ k+=i; return k; } int sub(int j){ k-=j; return k; } public static void main(String[] args){ TestInterface ti = new TestInterface(); ti.add(); ti.sub(); } } |
