聊一聊JavaScript和Java、C#的“箭头函数”（二）

let func = (s)=> { 
    console.log(s); 
};
var showLog = function(str,action){
    action(str);
}
showLog("hello world",func);

public static void main(String[] args) {
    Consumer<String> func = (String s)->{
        System.out.println(s);
    };
    showLog("hello world",func);
}
public static void showLog(String str, Consumer<String> action){
    action.accept(str);
}

public static void Main(string[] args)
{
    var func = (string s) => { Console.WriteLine(s); };
    showLog("hello world", func);
}
public static void showLog(string str ,Action<string> action) 
{ 
    action(str);
}
