定义和使用含有泛型的接口

/*

public interface GenericInterface<I> {
    public abstract void method(I i);
}

package demo02;

public class GenericInterfaceImpl implements  GenericInterface<String> {

    @Override
    public void method(String s) {
        System.out.println(s);

    }
}

测试含有泛型的接口

package demo02;
/*
  测试含有泛型的接口
*/
public class Demo01GenericInterface {
    public static void main(String[] args) {
        //创建GenericInterfaceImpl对象
        GenericInterfaceImpl g1=new GenericInterfaceImpl();
        g1.method("哒哒哒");
        System.out.println("--------------");
        //创建GenericInterfaceImpl对象
        GenericInterfaceImpl2<Integer> g2=new GenericInterfaceImpl2<>();
        g2.method(100);
    }
}
