package com.fanjia.day20200826;

/**

public class Demo06 {
    
    
    public static void main(String[] args) {
    
    
      /*  Inter in3 = new Inter() {
    
    
            @Override
            public int insert(int id, String name) {
    
    
                return 1;
            }
        };
        in3.insert(1,"lisi");
        */

       /* Inter in2 = (int id) -> {
    
    
            System.out.println("Lambda表达式");
            System.out.println(id);
        };
        in2.add(1);*/
        //in2.save();
        Inter in3 = (int id,String name) ->{
    
    
            System.out.println(id+":"+name);
            return 1;
        };
        in3.insert(3,"zhangsan");

    }
}
interface Inter{
    
    
    //void save();
    //void add(int id);
    int insert(int id,String name);
