Java 9接口中的私有方法
以下是一个示例，展示了如何在Java 9接口中使用私有方法 −
示例
interface my_int{ public abstract void multiply_vals(int a, int b); public default void add_vals(int a, int b){ sub_vals(a, b); System.out.print("Default method result "); System.out.println(a + b); } private void sub_vals(int a, int b){ System.out.print("Private method result "); System.out.println(a - b); } private static void div(int a, int b){ System.out.print(" Private static method result "); System.out.println(a / b); } } public class my_new_int implements my_int{ @Override public void multiply_vals(int a, int b){ System.out.print("Abstract method result "); System.out.println(a * b); } public static void main(String[] args){ my_int in = new my_new_int(); in.multiply_vals(11, 34); in.add_vals(78, 0); } }登录后复制
